147 mHz, then the input frequency (listening) is 600 kilohertz above. Quad: A quad is a specific style of directional antenna that is employed via square element arraignments that are a quarter wavelength apart. Before it opens up, the receiver must receive a signal on its input or receive frequency. How to find ham radio call signs available to you. The input, or the frequency the repeater receiver transmits on 443.700, but receives on 448.700 (+5 MHz offset). Spurious Emissions: These are signals from a radio transmitter that are undesired and outside of the tuned frequency range. The mostcommon frequencies for local communication in these bands are: 1. The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your … This is used for computer keyboard to computer keyboard communication. Positive Offset: This is a radio repeater input frequency that is higher input than the repeaters output frequency. In this first post, we’ll walk through setting up a BaoFeng UV-5R to use a repeater with a PL or CTCSS tones. Ham radio has evolved, albeit slowly compared to other technology sectors. OSCAR: Orbiting Satellite Carrying Amateur Radio. VEC: Stands for Volunteer Examiner Coordinator. We shouldn’t fight it. USB is used in Single Sideband radio operations. Mixer: An RF radio receiver component that is capable of combining two radio signals and output signals that are the sum and difference of the frequency of the two radio input frequencies. Each signal can be a question or an answer, as shown in the Meaning column. It is an award from the IARU and administered by ARRL. I understand the offsets. The good news is, that most of the HAM radios sold today, will set the offset automatically, once you have chosen your desired operating frequency. There are hundreds of thousands of amateur radio operators in the U.S. and millions around the world. Usually measures ½ wavelength long, each of the two segments is at ¼ wavelength. The signal must also have a tone to determine that the station being received at the repeater wants its transmission to be re-radiated. XIT: Stands for Transmitter Incremental Tuning. Suppose a food delivery service and a laundromat share a two-way radio frequency. Basically, it handles the repeater station ID using either voice or CW and activates the transmitter at the appropriate times. MARS: Military Affiliate Radio System – military affiliated amateur ham operators and radio stations that provide free of charge communications for deployed military personnel and others in official federal service. An antenna is used to transmit and receive signals that go in and out of a repeater. EMF: Electromotive Force (E) – voltage; unit of measure in volts. SSTV: Stands for Slow Scan TV.

Ground Plane: Is a horizontal conducting surface, or it is a radials extending from the base of the antenna (which is usually a quarterwave vertical antenna) that also produces a virtual image ground element for the antenna, which enhances performance. During the daylight it is two layers, F1 and F2 present. Odd splits are frequently used with satellite radio operations and with cross band radio repeater functions on some amateur radio transceivers. Let’s not fight it. As mentioned earlier, CTCSS uses a tone carried through the signal of the transmitter to access the repeater. NVIS: Near Vertical Incidence Skywave – radio propagation in which signals are then reflected from the earth’s ionosphere from a very steep vertical send off angle, which is resulting in a relatively short skywave skip distance. How do I know which Frequency is the receive frequency I transmit to on a Duplex repeater? For example, use as an oscillating radio wave’s electric and magnetic fields in use. Dual Band: An antenna that is designed for usage on two different radio broadcast bands; so a transceiver that operates on two different radio bands. Based in Geneva, Switzerland, the ITU is a subsidiary agencyof the United Nations. If the output frequency (transmit) of the repeater > 447 MHz, then the input frequency (listening) is 5 megahertz above. The 2-meter band’s offsets are set 600 kHz apart (As a rule of thumb), The 70 cm band offsets are 5MHz apart (again, rule of thumb). JOTA: Jamboree On The Air – is an annual Boy Scout radio event in which scouts and hams team up to make contacts with other scouting groups all around the world with amateur ham radio. VHF: Very High Frequency – 30 – 300 MHz frequency. This is called a “negative offset”. Thank you. In turn these are represented on the radio signal by a shift between two frequencies, one frequency signifying a mark or high voltage and another frequency representing a space of a low voltage. Depending on your license class, you can select any available call sign in the groups listed below. Europe, for example, used 1750 Hz as their standard frequency. If your HAM radio, (base, mobile or handheld) does not transmit the correct tone, the repeater’s receiver will not hear you (or pretends to not hear you) and won’t allow your station to transmit to it, until you set the proper tone to activate, when you broadcast or transmit. The code representing the letters consists of a series of bits represented by high and low voltages. Not as common today. The origins of amateur radio can be traced to the late 19th century, but amateur radio as practiced today began in the early 20th century. can you email me i need help using the local repeater to extend my reach to my wifes radio. Amazon Affiliate program disclosure:       As an Amazon Associate I earn from qualifying purchases made when certain links are clicked on at no extra cost to you. Next article BSI – National Standards Body of the UK If the output frequency (transmit) of the repeater < 447 MHz, then the input frequency (listening) is 5 megahertz lower. Ohm: Is the unit of electrical measurements for electrical resistance and electrical impedance. Alternatives for satellite radio operations, the radio frequency ranges used for uplink and downlink for satellite radio communications. We can’t fight it. Thanks to technology and ham radio ingenuity, there are ways to coexist with Big Brother and still enjoy the hobby. As soon as I release the transmit button so I can listen, the radio switches back to 443.700. I noticed my BaoFeng had an rToneFrequency that did not transfer over to the new radio. This is a phase shift that utilizes a digital mode in order to encode characters at 31.25 baud rate. Repeaters are not necessarily “high powered”, but always take advantage of elevation and better antennas and feedlines (as stated above). Repeaters are designed to not transmit noise and spurious signals. PTT: Stands for push to talk. Usually, only the first transmission requires a tone burst. You have entered an incorrect email address! As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Portable: This refers to a ham radio base station that is capable of being easily moved from one location to another for operation on the go. DCS: Digital Coded Squelch – is a method of breaking down the squelch of a receiver (especially a repeater station) using a digital code at the start of the transmission. Layer: A layer of the ionosphere that is approximately 55 to 90 miles high and that typically fades away after sunset ocurrs. This is a method to allow a non licensed person to communicate over ham radio with the help of a licensed radio operator. Traditionally, the beginning of every transmission used a simple tone burst to access the repeater. Used in superheterodyne receivers used to produce the intermediate radio frequency. The ionosphere is able to bend radio frequencies back toward the surface of the earth, providing the long distance, signal “skip.”. The food delivery service crew have to listen to the laundromat crew and vice versa. Ham radio can be useful in spreading information during emergencies when other services such as telephones, television or the Internet fail. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Your handheld transceiver or mobile ham radio has a very limited range. That is usually not any more than a few hundred miles in total. Continuous Tone Coded Squelch System, or CTCSS is a communications industry, Motorola decided that they needed their own proprietary name for CTCSS and called their version of it PL (. TNC: Stands for Terminal Node Controller. World's Largest Supplier of Amateur Radio, Ham Radio, and Communication Equipment. RACES: Stand for Radio Amateur Civil Emergency Service. Although this amateur radio abbreviation was reputed to have started when Morse telegraph operators sued to send two dashed, six dots and two dashes as a greeting, it has been widely adopted by radio amateurs using both Morse and also within 'fone' transmissions. It is an ARRL award to confirm contact in all 50 US states. AOS: Acquisition of Signal – Is a Satellite signal reception that only occurs when the satellite comes up over the top of the horizon. QRP: This is a Q signal (see Q signal) that stands for reduced power and also a low power radio station operating at five watts or fewer. A ham radio call sign is a designation given to an amateur radio operator by a licensing board. Quarter-wavelength vertical antenna-- An antenna constructed of a quarter-wavelength long radiating element placed perpendicular to the earth. Fred is the Ready Zeal owner and editor. As the number of repeaters continued to rise, channels had to be reused frequently. NiCad: Nickel Cadmium, a common type of rechargeable battery. (Note: No new Novice and Advanced licenses are being issued.) In our next post, we’ll show you how to configure your Budget Ham Radios for repeaters and tones. PL and CTCSS are used to prevent a repeater from responding to unwanted signals or interference. They are not for use in casual amateur conversation. Downlink: When referencing satellite communication operations it is a frequency used for the satellite-to-earth channel. This signal should be strong enough for re-transmission. LSB: Lower Side Band – the single sideband used tradition for bands below 30-meters. This call sign identifies the operator to anyone who might hear his or her transmission.The ham radio call sign must announced at the and end of each transmission, and at least once every ten minutes during a transmission. The good news is, that most of the modern ham radios take the offsets into account and will compensate automatically. The unit of frequency is measured is hertz. 6.) RTTY: Radio Teletype which is a digital mode of communication. If both groups use radios without CTCSS, they can hear all transmissions. In radio operations, impedance is desired to be matched and equal to transceiver to feedline to antenna for the best ham radio system performance. Double: On a repeater is 2 radio stations transmitting simultaneously. Do NOT follow this link or you will be banned from the site. Green Stamp: A US dollar mailed with a QSL card to pay for postage of a return QSL card. This was done to prevent one group from overhearing another group’s conversations even if they share the same frequency. The exciter modulates the audio from the receiver while the power amplifier boosts the audio level so the signal can travel further. Sporadic E: Sporadic E is when irregular patches of the E layer of the ionosphere activation are randomly refracted at higher frequency signals than are usually skipped. HAM RADIO TERMS. Despite these differences, the overall concept of how a repeater works and how it must be operated is generally the same. This often is on an HF SSB and used to minimize congestion on the transmitting frequency. Split Operating: Split operating is when transmission from one frequency while listening on a different radio frequency. It is done through its varying wavephase characteristics. I’m Tobias, The Geek Prepper. Shack: A slang term for the location of a ham radio operators rig. Phase: A phase is referring to RF waveforms and their position relative to the oscillation of electric and also magnetic fields of the compared waveforms. Tone: (See CTCSS) Tone refers to transmitted subaudible tones from the opening of the squelch. CW: Continuous Wave – a transmission mode employing an unmodulated transmission (continuous wave) and also Morse Code patterns of transmission or interruption to send a signal. Get your license — please. ham definition: 1. pig's meat from the leg or shoulder, preserved with salt or smoke 2. an actor whose style of…. International Q Code is an abbreviated way to exchange a great deal of information with a simple code. I will look into that for a new article. This is a group of volunteer radio operators who assist civil authorities during an emergency situation. Selectivity: This refers to a radio receivers effectiveness at rejecting radio signals on adjacent frequencies. Whoever wrote this page did a great job. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Product Detector: The product detector is a radio receiver circuit that is consisting of a mixer and also a oscillator. This extends the radios range. Sporadic E is generally used on the 6 meter band for skip propagation. Most repeaters are “PL’ed”, due to the sheer number of radios and repeaters in their area. This radio callbook lists wireless telegraphstations in Canada and the United States, including 89 amateur radio stations. SSTV is a amateur ham radio television transmission that utilizes 3 kHz of bandwidth that is transmitting only single frame images. Common in ham radio operation equipment. A ham radio antenna is sometimes referred to as a load on the transmitter circuit as well. SWR: Stands for Standing Wave Ratio. Squelch: The squelch on a radio is the control for muting the audio of the transceiver when there are no signals being received. It is utilized to send activation codes. If there’s enough interest, we can discuss setting up the Yaesu FT-2900 and the FT-7800 for repeaters and tones too. Rubber Duck: A short rubberized radio antenna used on a handheld radio transceiver. 1.) Negative Offset: Radio repeater input frequency (transmits to) is lower than the repeater output (listen to) ham radio frequency. A typical tone burst can last for less than half a second and had to follow a specific frequency. Hamfest: A ham festival or gathering that at which ham operators and commercial businesses meet, trade, and display their equipment or techniques. To become a radio ham, you must pass an examination. These signals are derived from Morse Code. Open Repeater: A ham radio repeater that can be used by any amateur radio operator. As a radio operators we call ourselves “HAM” or “HAMS”. Ground Wave Propagation: Radio frequency propagation along the surface of the earth that can extend far beyond the visual horizon. Ground: The zero voltage reference point of a circuit. FSTV: Fast Scan Television: Used on the 70 cm and higher frequency bands with NTSC (standard broadcast) signal in order to transmit television imagery on the amateur ham bands. For example, television squelch settings are usually preset. It also removes the tone to ensure that only the required audio is transmitted to the receiver. E–Skip: Also “Sporadic E” (see sporadic E) signal propagation using reflection by the E-Layer of the ionosphere in an e skip. Discussion of “channels” is misleading since amateur radio focuses on frequency, not an organizational scheme of specific frequencies labelled as “channels”. Third Party Communications: This refers to communication sent by one ham radio operator on behalf of an operator unable to send the communication themselves. It is also commonly known as Coordinated Universal Time. Output Frequency: Used for a ham radio repeater, it is the frequency of re-transmission, aka the “listen to” frequency. This scenario is obviously undesirable. If there are several groups of users on one radio frequency, CTCSS mutes users who are using a different CTCSS tone or no CTCSS at all. Geekprepper.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. F-Layer: The highest possible layers of the ionosphere, from approximately 90 to 250 miles high in total, that provide the longest propagation skips available with HF frequencies of 30 MHz or lower. A transmitter has two main components: an exciter and a power amplifier. This is generally performed by repeater stations in order to communicate between phones and two way radios. Magnetic Mount (mag-mount): Is a ham radio antenna that easily installs to a car or metal surface using a magnet. Repeater Directory: This is public listing of all repeaters. Uplink: Uplink is the frequency used for earth-to-satellite radio transmissions. XIT provides slight changes in the radio transmit frequency without effecting the radio’s receive frequency.

Packet Radio: Radio utilizing digital radio bursts for transmissions of communications. Pile–up: A pile up is when multiple ham radios attempt to make calls to the same station at the same time. I’ll keep watching this website. Repeater: A repeater is a radio station that receives a radio transmission and then re transmits the original frequency as a different frequency at higher power, or from a higher position. QSL: This is a Q signal (see Q signal) that stands for acknowledged receipt of message. We’ll follow up with a 2nd post showing you how to configure a TYT TH-UVF1 to do the same. the sideband is made of frequencies that are higher than the carrier frequency the transceiver is tuned to. Plain vs Serrated Edge Knife: What’s the Best for Survival? Hams and HAM Radio. It is a CQ magazine award for confirmed contact with each of the 40 world zones. Your email address will not be published. Then I can hear transmissions on the repeater’s output frequency. I’m not sure if this has anything to do with my issues, or how to add a column in the RT System to add rToneFrequencies. It's fun, social, educational, and can be a … Ionosphere: Is the layers of the atmosphere of the earth that is charged with particles that are induced by the rays of the sun. Field Day: An annual amateur radio event to practice emergency communications with other ham operators. Example: If the repeater output is 443.700 Mhz (70cm band). Picket Fencing: Picket fencing is when there is a rapid fluctuation in sound or a signal that is caused by a radio station that is moving during a transmission. Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. You can have the old reliable HAM devices, however, there are so many unanswered questions for the new HAM licensee. But we still don’t know how to use a radio (Baofeng). Half-Wave Dipole: Is a simple antenna that is fed at the center point of the antenna with two one-quarter wave elements that are extending in opposite directions (one attached to the feedline conductor, and another one to the feedline ground or shield). This radio information may be Morse Code, or it can be voice, digital, or other communication forms. 807: A deceptive ham term for ale and also a popular transmitting tube of the early 20th century. Antenna Gain: An increase in the antenna transmission and the reception performance in a particular direction with the expense of performance in other directions, performance will increase as compared to an isotropic antenna and a dipole antenna. Responsible for “Sporadic E” (see sporadic E) communications with frequencies above 30 MHz (which is especially for the 6 meter band). Q-signals or codes are a set of abbreviations for common radio information that can help save time and allow communication between operators who don’t speak a common language. Gray Line: The transition area line on the earth separating daylight and darkness. The First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. -- Ham radio Q signal meaning "Is this frequency in use?" For more ham radio guides and tips read the articles below: AGC: Automatic Gain Control – another radio circuit that will automatically adjust receiver gain. Negative: On-the-air slang term meaning “No” or “Incorrect”. HAM RADIO TERMS GLOSSARY This is glossary contains general definitions of typical amateur radio terms. I’ve not been able to find out how to set the rToneFrequency. Zepp Antenna: An end-fed wire radio antenna that is reeled down and up from Zeppelin aircraft. Full Quieting: Most commonly used to describe the repeater audio to having no noise component, while referring to a received signal strength by the repeater so that there is sufficient to engage the receiver limiters. ADIF: Amateur Data Interchange Format, a standard specification for the format of exported logbook files. 73 - Best regards, a greeting sent by radio amateurs over the air. Ham radio, also known as amateur radio is a popular hobby among most people in America. Traffic: Traffic refers to a radio message that has been distributed over a net. A repeater is just another two-way radio. Eleven Meter Band: The specific radio band in which citizens radio (CB radio) channels are found. NVIS is typical on low HF radio bands which are (40m, 60m, 80m) where horizontally polarized ham radio antennas are then raised to much less than a half-wavelength above the ground. 2 meters (~144-148MHz)* 2. If you can’t reach anyone, then you may have to take things to the next level and use a repeater. USB: Stands for Upper Sideband. Glen Zook, K9STH, posted this to the Heathkit mailing list: Many amateurs already know that "73" is from what is known as the "Phillips Code", a series of numeric messages conceived for the purpose of cutting down transmission time on the old land telegraph systems when sending text that is basically the same. 3.)

Quad: A quad is a specific style of directional antenna that is employed via square element arraignments that are a quarter wavelength apart. Before it opens up, the receiver must receive a signal on its input or receive frequency. How to find ham radio call signs available to you. The input, or the frequency the repeater receiver transmits on 443.700, but receives on 448.700 (+5 MHz offset). Spurious Emissions: These are signals from a radio transmitter that are undesired and outside of the tuned frequency range. The mostcommon frequencies for local communication in these bands are: 1. The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your … This is used for computer keyboard to computer keyboard communication. Positive Offset: This is a radio repeater input frequency that is higher input than the repeaters output frequency. In this first post, we’ll walk through setting up a BaoFeng UV-5R to use a repeater with a PL or CTCSS tones. Ham radio has evolved, albeit slowly compared to other technology sectors. OSCAR: Orbiting Satellite Carrying Amateur Radio. VEC: Stands for Volunteer Examiner Coordinator. We shouldn’t fight it. USB is used in Single Sideband radio operations. Mixer: An RF radio receiver component that is capable of combining two radio signals and output signals that are the sum and difference of the frequency of the two radio input frequencies. Each signal can be a question or an answer, as shown in the Meaning column. It is an award from the IARU and administered by ARRL. I understand the offsets. The good news is, that most of the HAM radios sold today, will set the offset automatically, once you have chosen your desired operating frequency. There are hundreds of thousands of amateur radio operators in the U.S. and millions around the world. Usually measures ½ wavelength long, each of the two segments is at ¼ wavelength. The signal must also have a tone to determine that the station being received at the repeater wants its transmission to be re-radiated. XIT: Stands for Transmitter Incremental Tuning. Suppose a food delivery service and a laundromat share a two-way radio frequency. Basically, it handles the repeater station ID using either voice or CW and activates the transmitter at the appropriate times. MARS: Military Affiliate Radio System – military affiliated amateur ham operators and radio stations that provide free of charge communications for deployed military personnel and others in official federal service. An antenna is used to transmit and receive signals that go in and out of a repeater. EMF: Electromotive Force (E) – voltage; unit of measure in volts. SSTV: Stands for Slow Scan TV. Impedance: The opposition to the flow of the alternating current AC, measured in the unit ohms. DXCC: is an ARRL award for confirmation of contacts made in a minimum of 100 different countries. Ground Plane: Is a horizontal conducting surface, or it is a radials extending from the base of the antenna (which is usually a quarterwave vertical antenna) that also produces a virtual image ground element for the antenna, which enhances performance. During the daylight it is two layers, F1 and F2 present. Odd splits are frequently used with satellite radio operations and with cross band radio repeater functions on some amateur radio transceivers. Let’s not fight it. As mentioned earlier, CTCSS uses a tone carried through the signal of the transmitter to access the repeater. NVIS: Near Vertical Incidence Skywave – radio propagation in which signals are then reflected from the earth’s ionosphere from a very steep vertical send off angle, which is resulting in a relatively short skywave skip distance. How do I know which Frequency is the receive frequency I transmit to on a Duplex repeater? For example, use as an oscillating radio wave’s electric and magnetic fields in use. Dual Band: An antenna that is designed for usage on two different radio broadcast bands; so a transceiver that operates on two different radio bands. Based in Geneva, Switzerland, the ITU is a subsidiary agencyof the United Nations. If the output frequency (transmit) of the repeater > 447 MHz, then the input frequency (listening) is 5 megahertz above. The 2-meter band’s offsets are set 600 kHz apart (As a rule of thumb), The 70 cm band offsets are 5MHz apart (again, rule of thumb). JOTA: Jamboree On The Air – is an annual Boy Scout radio event in which scouts and hams team up to make contacts with other scouting groups all around the world with amateur ham radio. VHF: Very High Frequency – 30 – 300 MHz frequency. This is called a “negative offset”. Thank you. In turn these are represented on the radio signal by a shift between two frequencies, one frequency signifying a mark or high voltage and another frequency representing a space of a low voltage. Depending on your license class, you can select any available call sign in the groups listed below. Europe, for example, used 1750 Hz as their standard frequency. If your HAM radio, (base, mobile or handheld) does not transmit the correct tone, the repeater’s receiver will not hear you (or pretends to not hear you) and won’t allow your station to transmit to it, until you set the proper tone to activate, when you broadcast or transmit. The code representing the letters consists of a series of bits represented by high and low voltages. Not as common today. The origins of amateur radio can be traced to the late 19th century, but amateur radio as practiced today began in the early 20th century. can you email me i need help using the local repeater to extend my reach to my wifes radio. Amazon Affiliate program disclosure:       As an Amazon Associate I earn from qualifying purchases made when certain links are clicked on at no extra cost to you. Next article BSI – National Standards Body of the UK If the output frequency (transmit) of the repeater < 447 MHz, then the input frequency (listening) is 5 megahertz lower. Ohm: Is the unit of electrical measurements for electrical resistance and electrical impedance. Alternatives for satellite radio operations, the radio frequency ranges used for uplink and downlink for satellite radio communications. We can’t fight it. Thanks to technology and ham radio ingenuity, there are ways to coexist with Big Brother and still enjoy the hobby. As soon as I release the transmit button so I can listen, the radio switches back to 443.700. I noticed my BaoFeng had an rToneFrequency that did not transfer over to the new radio. This is a phase shift that utilizes a digital mode in order to encode characters at 31.25 baud rate. Repeaters are not necessarily “high powered”, but always take advantage of elevation and better antennas and feedlines (as stated above). Repeaters are designed to not transmit noise and spurious signals. PTT: Stands for push to talk. Usually, only the first transmission requires a tone burst. You have entered an incorrect email address! As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Portable: This refers to a ham radio base station that is capable of being easily moved from one location to another for operation on the go. DCS: Digital Coded Squelch – is a method of breaking down the squelch of a receiver (especially a repeater station) using a digital code at the start of the transmission. Layer: A layer of the ionosphere that is approximately 55 to 90 miles high and that typically fades away after sunset ocurrs. This is a method to allow a non licensed person to communicate over ham radio with the help of a licensed radio operator. Traditionally, the beginning of every transmission used a simple tone burst to access the repeater. Used in superheterodyne receivers used to produce the intermediate radio frequency. The ionosphere is able to bend radio frequencies back toward the surface of the earth, providing the long distance, signal “skip.”. The food delivery service crew have to listen to the laundromat crew and vice versa. Ham radio can be useful in spreading information during emergencies when other services such as telephones, television or the Internet fail. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Your handheld transceiver or mobile ham radio has a very limited range. That is usually not any more than a few hundred miles in total. Continuous Tone Coded Squelch System, or CTCSS is a communications industry, Motorola decided that they needed their own proprietary name for CTCSS and called their version of it PL (. TNC: Stands for Terminal Node Controller. World's Largest Supplier of Amateur Radio, Ham Radio, and Communication Equipment. RACES: Stand for Radio Amateur Civil Emergency Service. Although this amateur radio abbreviation was reputed to have started when Morse telegraph operators sued to send two dashed, six dots and two dashes as a greeting, it has been widely adopted by radio amateurs using both Morse and also within 'fone' transmissions. It is an ARRL award to confirm contact in all 50 US states. AOS: Acquisition of Signal – Is a Satellite signal reception that only occurs when the satellite comes up over the top of the horizon. QRP: This is a Q signal (see Q signal) that stands for reduced power and also a low power radio station operating at five watts or fewer. A ham radio call sign is a designation given to an amateur radio operator by a licensing board. Quarter-wavelength vertical antenna-- An antenna constructed of a quarter-wavelength long radiating element placed perpendicular to the earth. Fred is the Ready Zeal owner and editor. As the number of repeaters continued to rise, channels had to be reused frequently. NiCad: Nickel Cadmium, a common type of rechargeable battery. (Note: No new Novice and Advanced licenses are being issued.) In our next post, we’ll show you how to configure your Budget Ham Radios for repeaters and tones. PL and CTCSS are used to prevent a repeater from responding to unwanted signals or interference. They are not for use in casual amateur conversation. Downlink: When referencing satellite communication operations it is a frequency used for the satellite-to-earth channel. This signal should be strong enough for re-transmission. LSB: Lower Side Band – the single sideband used tradition for bands below 30-meters. This call sign identifies the operator to anyone who might hear his or her transmission.The ham radio call sign must announced at the and end of each transmission, and at least once every ten minutes during a transmission. The good news is, that most of the modern ham radios take the offsets into account and will compensate automatically. The unit of frequency is measured is hertz. 6.) RTTY: Radio Teletype which is a digital mode of communication. If both groups use radios without CTCSS, they can hear all transmissions. In radio operations, impedance is desired to be matched and equal to transceiver to feedline to antenna for the best ham radio system performance. Double: On a repeater is 2 radio stations transmitting simultaneously. Do NOT follow this link or you will be banned from the site. Green Stamp: A US dollar mailed with a QSL card to pay for postage of a return QSL card. This was done to prevent one group from overhearing another group’s conversations even if they share the same frequency. The exciter modulates the audio from the receiver while the power amplifier boosts the audio level so the signal can travel further. Sporadic E: Sporadic E is when irregular patches of the E layer of the ionosphere activation are randomly refracted at higher frequency signals than are usually skipped. HAM RADIO TERMS. Despite these differences, the overall concept of how a repeater works and how it must be operated is generally the same. This often is on an HF SSB and used to minimize congestion on the transmitting frequency. Split Operating: Split operating is when transmission from one frequency while listening on a different radio frequency. It is done through its varying wavephase characteristics. I’m Tobias, The Geek Prepper. Shack: A slang term for the location of a ham radio operators rig.

Tone: (See CTCSS) Tone refers to transmitted subaudible tones from the opening of the squelch. CW: Continuous Wave – a transmission mode employing an unmodulated transmission (continuous wave) and also Morse Code patterns of transmission or interruption to send a signal. Get your license — please. ham definition: 1. pig's meat from the leg or shoulder, preserved with salt or smoke 2. an actor whose style of…. International Q Code is an abbreviated way to exchange a great deal of information with a simple code. I will look into that for a new article. This is a group of volunteer radio operators who assist civil authorities during an emergency situation. Selectivity: This refers to a radio receivers effectiveness at rejecting radio signals on adjacent frequencies. Whoever wrote this page did a great job. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Product Detector: The product detector is a radio receiver circuit that is consisting of a mixer and also a oscillator. This extends the radios range. Sporadic E is generally used on the 6 meter band for skip propagation. Most repeaters are “PL’ed”, due to the sheer number of radios and repeaters in their area. This radio callbook lists wireless telegraphstations in Canada and the United States, including 89 amateur radio stations. SSTV is a amateur ham radio television transmission that utilizes 3 kHz of bandwidth that is transmitting only single frame images. Common in ham radio operation equipment. A ham radio antenna is sometimes referred to as a load on the transmitter circuit as well. SWR: Stands for Standing Wave Ratio. Squelch: The squelch on a radio is the control for muting the audio of the transceiver when there are no signals being received. It is utilized to send activation codes. If there’s enough interest, we can discuss setting up the Yaesu FT-2900 and the FT-7800 for repeaters and tones too. Rubber Duck: A short rubberized radio antenna used on a handheld radio transceiver. 1.) Negative Offset: Radio repeater input frequency (transmits to) is lower than the repeater output (listen to) ham radio frequency. A typical tone burst can last for less than half a second and had to follow a specific frequency. Hamfest: A ham festival or gathering that at which ham operators and commercial businesses meet, trade, and display their equipment or techniques. To become a radio ham, you must pass an examination. These signals are derived from Morse Code. Open Repeater: A ham radio repeater that can be used by any amateur radio operator. As a radio operators we call ourselves “HAM” or “HAMS”. Ground Wave Propagation: Radio frequency propagation along the surface of the earth that can extend far beyond the visual horizon. Ground: The zero voltage reference point of a circuit. FSTV: Fast Scan Television: Used on the 70 cm and higher frequency bands with NTSC (standard broadcast) signal in order to transmit television imagery on the amateur ham bands. For example, television squelch settings are usually preset. It also removes the tone to ensure that only the required audio is transmitted to the receiver. E–Skip: Also “Sporadic E” (see sporadic E) signal propagation using reflection by the E-Layer of the ionosphere in an e skip. Discussion of “channels” is misleading since amateur radio focuses on frequency, not an organizational scheme of specific frequencies labelled as “channels”. Third Party Communications: This refers to communication sent by one ham radio operator on behalf of an operator unable to send the communication themselves. It is also commonly known as Coordinated Universal Time. Output Frequency: Used for a ham radio repeater, it is the frequency of re-transmission, aka the “listen to” frequency. This scenario is obviously undesirable. If there are several groups of users on one radio frequency, CTCSS mutes users who are using a different CTCSS tone or no CTCSS at all. Geekprepper.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. F-Layer: The highest possible layers of the ionosphere, from approximately 90 to 250 miles high in total, that provide the longest propagation skips available with HF frequencies of 30 MHz or lower. A transmitter has two main components: an exciter and a power amplifier. This is generally performed by repeater stations in order to communicate between phones and two way radios. Magnetic Mount (mag-mount): Is a ham radio antenna that easily installs to a car or metal surface using a magnet. Repeater Directory: This is public listing of all repeaters. Uplink: Uplink is the frequency used for earth-to-satellite radio transmissions. XIT provides slight changes in the radio transmit frequency without effecting the radio’s receive frequency.

Packet Radio: Radio utilizing digital radio bursts for transmissions of communications. Pile–up: A pile up is when multiple ham radios attempt to make calls to the same station at the same time. I’ll keep watching this website. Repeater: A repeater is a radio station that receives a radio transmission and then re transmits the original frequency as a different frequency at higher power, or from a higher position. QSL: This is a Q signal (see Q signal) that stands for acknowledged receipt of message. We’ll follow up with a 2nd post showing you how to configure a TYT TH-UVF1 to do the same. the sideband is made of frequencies that are higher than the carrier frequency the transceiver is tuned to. Plain vs Serrated Edge Knife: What’s the Best for Survival? Hams and HAM Radio. It is a CQ magazine award for confirmed contact with each of the 40 world zones. Your email address will not be published. Then I can hear transmissions on the repeater’s output frequency. I’m not sure if this has anything to do with my issues, or how to add a column in the RT System to add rToneFrequencies. It's fun, social, educational, and can be a … Ionosphere: Is the layers of the atmosphere of the earth that is charged with particles that are induced by the rays of the sun. Field Day: An annual amateur radio event to practice emergency communications with other ham operators. Example: If the repeater output is 443.700 Mhz (70cm band). Picket Fencing: Picket fencing is when there is a rapid fluctuation in sound or a signal that is caused by a radio station that is moving during a transmission. Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. You can have the old reliable HAM devices, however, there are so many unanswered questions for the new HAM licensee. But we still don’t know how to use a radio (Baofeng). Half-Wave Dipole: Is a simple antenna that is fed at the center point of the antenna with two one-quarter wave elements that are extending in opposite directions (one attached to the feedline conductor, and another one to the feedline ground or shield). This radio information may be Morse Code, or it can be voice, digital, or other communication forms. 807: A deceptive ham term for ale and also a popular transmitting tube of the early 20th century. Antenna Gain: An increase in the antenna transmission and the reception performance in a particular direction with the expense of performance in other directions, performance will increase as compared to an isotropic antenna and a dipole antenna. Responsible for “Sporadic E” (see sporadic E) communications with frequencies above 30 MHz (which is especially for the 6 meter band). Q-signals or codes are a set of abbreviations for common radio information that can help save time and allow communication between operators who don’t speak a common language. Gray Line: The transition area line on the earth separating daylight and darkness. The First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. -- Ham radio Q signal meaning "Is this frequency in use?" For more ham radio guides and tips read the articles below: AGC: Automatic Gain Control – another radio circuit that will automatically adjust receiver gain. Negative: On-the-air slang term meaning “No” or “Incorrect”. HAM RADIO TERMS GLOSSARY This is glossary contains general definitions of typical amateur radio terms. I’ve not been able to find out how to set the rToneFrequency. Zepp Antenna: An end-fed wire radio antenna that is reeled down and up from Zeppelin aircraft. Full Quieting: Most commonly used to describe the repeater audio to having no noise component, while referring to a received signal strength by the repeater so that there is sufficient to engage the receiver limiters. ADIF: Amateur Data Interchange Format, a standard specification for the format of exported logbook files. 73 - Best regards, a greeting sent by radio amateurs over the air. Ham radio, also known as amateur radio is a popular hobby among most people in America. Traffic: Traffic refers to a radio message that has been distributed over a net. A repeater is just another two-way radio. Eleven Meter Band: The specific radio band in which citizens radio (CB radio) channels are found. NVIS is typical on low HF radio bands which are (40m, 60m, 80m) where horizontally polarized ham radio antennas are then raised to much less than a half-wavelength above the ground. 2 meters (~144-148MHz)* 2. If you can’t reach anyone, then you may have to take things to the next level and use a repeater. USB: Stands for Upper Sideband. Glen Zook, K9STH, posted this to the Heathkit mailing list: Many amateurs already know that "73" is from what is known as the "Phillips Code", a series of numeric messages conceived for the purpose of cutting down transmission time on the old land telegraph systems when sending text that is basically the same. 3.)

ham radio meaning

Milli: Prefix meaning 1/1000 (one one-thousandth). Learn more. FCC: Federal Communications Commission – is the US federal government agency that regulates all the radio spectrum and that also sanctions the amateur ham radio service. How the software settings differ from the BaoFeng settings using the RT Software. Load: Is a radio device in an electric circuit capable of consuming, converting, and radiating energy. Is this series available in pdf fomat for us older slower page turners? Amateur radio operators call themselves "radio hams" or simply "hams." Handheld: (Handheld Transceiver / HT) – a small transceiver that can be carried in the hand. Q–Signal: A Q signal are common used questions and statements abbreviated to three letters. A net is usually headed by a net control radio station that managed all the radio message traffic and radio transmissions in an proper order. Duplex: A radio communication mode that allows simultaneous transmitting and receiving (on two different frequencies). ‘A radio ham from way back, Addis says that he simply progressed from making little transmitters to building bigger and more sophisticated receivers and antennae.’ ‘But not by Grote Reber, a radio ham from Illinois who later moved to Tasmania.’ ‘So if I become a radio ham, then I can talk to the people from various parts of the world.’ In real life, many users can co-exist in a single radio channel. If the output frequency (transmit) of the repeater > 147 mHz, then the input frequency (listening) is 600 kilohertz above. Quad: A quad is a specific style of directional antenna that is employed via square element arraignments that are a quarter wavelength apart. Before it opens up, the receiver must receive a signal on its input or receive frequency. How to find ham radio call signs available to you. The input, or the frequency the repeater receiver transmits on 443.700, but receives on 448.700 (+5 MHz offset). Spurious Emissions: These are signals from a radio transmitter that are undesired and outside of the tuned frequency range. The mostcommon frequencies for local communication in these bands are: 1. The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your … This is used for computer keyboard to computer keyboard communication. Positive Offset: This is a radio repeater input frequency that is higher input than the repeaters output frequency. In this first post, we’ll walk through setting up a BaoFeng UV-5R to use a repeater with a PL or CTCSS tones. Ham radio has evolved, albeit slowly compared to other technology sectors. OSCAR: Orbiting Satellite Carrying Amateur Radio. VEC: Stands for Volunteer Examiner Coordinator. We shouldn’t fight it. USB is used in Single Sideband radio operations. Mixer: An RF radio receiver component that is capable of combining two radio signals and output signals that are the sum and difference of the frequency of the two radio input frequencies. Each signal can be a question or an answer, as shown in the Meaning column. It is an award from the IARU and administered by ARRL. I understand the offsets. The good news is, that most of the HAM radios sold today, will set the offset automatically, once you have chosen your desired operating frequency. There are hundreds of thousands of amateur radio operators in the U.S. and millions around the world. Usually measures ½ wavelength long, each of the two segments is at ¼ wavelength. The signal must also have a tone to determine that the station being received at the repeater wants its transmission to be re-radiated. XIT: Stands for Transmitter Incremental Tuning. Suppose a food delivery service and a laundromat share a two-way radio frequency. Basically, it handles the repeater station ID using either voice or CW and activates the transmitter at the appropriate times. MARS: Military Affiliate Radio System – military affiliated amateur ham operators and radio stations that provide free of charge communications for deployed military personnel and others in official federal service. An antenna is used to transmit and receive signals that go in and out of a repeater. EMF: Electromotive Force (E) – voltage; unit of measure in volts. SSTV: Stands for Slow Scan TV. Impedance: The opposition to the flow of the alternating current AC, measured in the unit ohms. DXCC: is an ARRL award for confirmation of contacts made in a minimum of 100 different countries. Ground Plane: Is a horizontal conducting surface, or it is a radials extending from the base of the antenna (which is usually a quarterwave vertical antenna) that also produces a virtual image ground element for the antenna, which enhances performance. During the daylight it is two layers, F1 and F2 present. Odd splits are frequently used with satellite radio operations and with cross band radio repeater functions on some amateur radio transceivers. Let’s not fight it. As mentioned earlier, CTCSS uses a tone carried through the signal of the transmitter to access the repeater. NVIS: Near Vertical Incidence Skywave – radio propagation in which signals are then reflected from the earth’s ionosphere from a very steep vertical send off angle, which is resulting in a relatively short skywave skip distance. How do I know which Frequency is the receive frequency I transmit to on a Duplex repeater? For example, use as an oscillating radio wave’s electric and magnetic fields in use. Dual Band: An antenna that is designed for usage on two different radio broadcast bands; so a transceiver that operates on two different radio bands. Based in Geneva, Switzerland, the ITU is a subsidiary agencyof the United Nations. If the output frequency (transmit) of the repeater > 447 MHz, then the input frequency (listening) is 5 megahertz above. The 2-meter band’s offsets are set 600 kHz apart (As a rule of thumb), The 70 cm band offsets are 5MHz apart (again, rule of thumb). JOTA: Jamboree On The Air – is an annual Boy Scout radio event in which scouts and hams team up to make contacts with other scouting groups all around the world with amateur ham radio. VHF: Very High Frequency – 30 – 300 MHz frequency. This is called a “negative offset”. Thank you. In turn these are represented on the radio signal by a shift between two frequencies, one frequency signifying a mark or high voltage and another frequency representing a space of a low voltage. Depending on your license class, you can select any available call sign in the groups listed below. Europe, for example, used 1750 Hz as their standard frequency. If your HAM radio, (base, mobile or handheld) does not transmit the correct tone, the repeater’s receiver will not hear you (or pretends to not hear you) and won’t allow your station to transmit to it, until you set the proper tone to activate, when you broadcast or transmit. The code representing the letters consists of a series of bits represented by high and low voltages. Not as common today. The origins of amateur radio can be traced to the late 19th century, but amateur radio as practiced today began in the early 20th century. can you email me i need help using the local repeater to extend my reach to my wifes radio. Amazon Affiliate program disclosure:       As an Amazon Associate I earn from qualifying purchases made when certain links are clicked on at no extra cost to you. Next article BSI – National Standards Body of the UK If the output frequency (transmit) of the repeater < 447 MHz, then the input frequency (listening) is 5 megahertz lower. Ohm: Is the unit of electrical measurements for electrical resistance and electrical impedance. Alternatives for satellite radio operations, the radio frequency ranges used for uplink and downlink for satellite radio communications. We can’t fight it. Thanks to technology and ham radio ingenuity, there are ways to coexist with Big Brother and still enjoy the hobby. As soon as I release the transmit button so I can listen, the radio switches back to 443.700. I noticed my BaoFeng had an rToneFrequency that did not transfer over to the new radio. This is a phase shift that utilizes a digital mode in order to encode characters at 31.25 baud rate. Repeaters are not necessarily “high powered”, but always take advantage of elevation and better antennas and feedlines (as stated above). Repeaters are designed to not transmit noise and spurious signals. PTT: Stands for push to talk. Usually, only the first transmission requires a tone burst. You have entered an incorrect email address! As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Portable: This refers to a ham radio base station that is capable of being easily moved from one location to another for operation on the go. DCS: Digital Coded Squelch – is a method of breaking down the squelch of a receiver (especially a repeater station) using a digital code at the start of the transmission. Layer: A layer of the ionosphere that is approximately 55 to 90 miles high and that typically fades away after sunset ocurrs. This is a method to allow a non licensed person to communicate over ham radio with the help of a licensed radio operator. Traditionally, the beginning of every transmission used a simple tone burst to access the repeater. Used in superheterodyne receivers used to produce the intermediate radio frequency. The ionosphere is able to bend radio frequencies back toward the surface of the earth, providing the long distance, signal “skip.”. The food delivery service crew have to listen to the laundromat crew and vice versa. Ham radio can be useful in spreading information during emergencies when other services such as telephones, television or the Internet fail. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Your handheld transceiver or mobile ham radio has a very limited range. That is usually not any more than a few hundred miles in total. Continuous Tone Coded Squelch System, or CTCSS is a communications industry, Motorola decided that they needed their own proprietary name for CTCSS and called their version of it PL (. TNC: Stands for Terminal Node Controller. World's Largest Supplier of Amateur Radio, Ham Radio, and Communication Equipment. RACES: Stand for Radio Amateur Civil Emergency Service. Although this amateur radio abbreviation was reputed to have started when Morse telegraph operators sued to send two dashed, six dots and two dashes as a greeting, it has been widely adopted by radio amateurs using both Morse and also within 'fone' transmissions. It is an ARRL award to confirm contact in all 50 US states. AOS: Acquisition of Signal – Is a Satellite signal reception that only occurs when the satellite comes up over the top of the horizon. QRP: This is a Q signal (see Q signal) that stands for reduced power and also a low power radio station operating at five watts or fewer. A ham radio call sign is a designation given to an amateur radio operator by a licensing board. Quarter-wavelength vertical antenna-- An antenna constructed of a quarter-wavelength long radiating element placed perpendicular to the earth. Fred is the Ready Zeal owner and editor. As the number of repeaters continued to rise, channels had to be reused frequently. NiCad: Nickel Cadmium, a common type of rechargeable battery. (Note: No new Novice and Advanced licenses are being issued.) In our next post, we’ll show you how to configure your Budget Ham Radios for repeaters and tones. PL and CTCSS are used to prevent a repeater from responding to unwanted signals or interference. They are not for use in casual amateur conversation. Downlink: When referencing satellite communication operations it is a frequency used for the satellite-to-earth channel. This signal should be strong enough for re-transmission. LSB: Lower Side Band – the single sideband used tradition for bands below 30-meters. This call sign identifies the operator to anyone who might hear his or her transmission.The ham radio call sign must announced at the and end of each transmission, and at least once every ten minutes during a transmission. The good news is, that most of the modern ham radios take the offsets into account and will compensate automatically. The unit of frequency is measured is hertz. 6.) RTTY: Radio Teletype which is a digital mode of communication. If both groups use radios without CTCSS, they can hear all transmissions. In radio operations, impedance is desired to be matched and equal to transceiver to feedline to antenna for the best ham radio system performance. Double: On a repeater is 2 radio stations transmitting simultaneously. Do NOT follow this link or you will be banned from the site. Green Stamp: A US dollar mailed with a QSL card to pay for postage of a return QSL card. This was done to prevent one group from overhearing another group’s conversations even if they share the same frequency. The exciter modulates the audio from the receiver while the power amplifier boosts the audio level so the signal can travel further. Sporadic E: Sporadic E is when irregular patches of the E layer of the ionosphere activation are randomly refracted at higher frequency signals than are usually skipped. HAM RADIO TERMS. Despite these differences, the overall concept of how a repeater works and how it must be operated is generally the same. This often is on an HF SSB and used to minimize congestion on the transmitting frequency. Split Operating: Split operating is when transmission from one frequency while listening on a different radio frequency. It is done through its varying wavephase characteristics. I’m Tobias, The Geek Prepper. Shack: A slang term for the location of a ham radio operators rig. Phase: A phase is referring to RF waveforms and their position relative to the oscillation of electric and also magnetic fields of the compared waveforms. Tone: (See CTCSS) Tone refers to transmitted subaudible tones from the opening of the squelch. CW: Continuous Wave – a transmission mode employing an unmodulated transmission (continuous wave) and also Morse Code patterns of transmission or interruption to send a signal. Get your license — please. ham definition: 1. pig's meat from the leg or shoulder, preserved with salt or smoke 2. an actor whose style of…. International Q Code is an abbreviated way to exchange a great deal of information with a simple code. I will look into that for a new article. This is a group of volunteer radio operators who assist civil authorities during an emergency situation. Selectivity: This refers to a radio receivers effectiveness at rejecting radio signals on adjacent frequencies. Whoever wrote this page did a great job. Some repeaters are set up to operate only when a PL tone of 179.9 Hz is picked up by its receiver, only then will it allow the transmitting station access. Product Detector: The product detector is a radio receiver circuit that is consisting of a mixer and also a oscillator. This extends the radios range. Sporadic E is generally used on the 6 meter band for skip propagation. Most repeaters are “PL’ed”, due to the sheer number of radios and repeaters in their area. This radio callbook lists wireless telegraphstations in Canada and the United States, including 89 amateur radio stations. SSTV is a amateur ham radio television transmission that utilizes 3 kHz of bandwidth that is transmitting only single frame images. Common in ham radio operation equipment. A ham radio antenna is sometimes referred to as a load on the transmitter circuit as well. SWR: Stands for Standing Wave Ratio. Squelch: The squelch on a radio is the control for muting the audio of the transceiver when there are no signals being received. It is utilized to send activation codes. If there’s enough interest, we can discuss setting up the Yaesu FT-2900 and the FT-7800 for repeaters and tones too. Rubber Duck: A short rubberized radio antenna used on a handheld radio transceiver. 1.) Negative Offset: Radio repeater input frequency (transmits to) is lower than the repeater output (listen to) ham radio frequency. A typical tone burst can last for less than half a second and had to follow a specific frequency. Hamfest: A ham festival or gathering that at which ham operators and commercial businesses meet, trade, and display their equipment or techniques. To become a radio ham, you must pass an examination. These signals are derived from Morse Code. Open Repeater: A ham radio repeater that can be used by any amateur radio operator. As a radio operators we call ourselves “HAM” or “HAMS”. Ground Wave Propagation: Radio frequency propagation along the surface of the earth that can extend far beyond the visual horizon. Ground: The zero voltage reference point of a circuit. FSTV: Fast Scan Television: Used on the 70 cm and higher frequency bands with NTSC (standard broadcast) signal in order to transmit television imagery on the amateur ham bands. For example, television squelch settings are usually preset. It also removes the tone to ensure that only the required audio is transmitted to the receiver. E–Skip: Also “Sporadic E” (see sporadic E) signal propagation using reflection by the E-Layer of the ionosphere in an e skip. Discussion of “channels” is misleading since amateur radio focuses on frequency, not an organizational scheme of specific frequencies labelled as “channels”. Third Party Communications: This refers to communication sent by one ham radio operator on behalf of an operator unable to send the communication themselves. It is also commonly known as Coordinated Universal Time. Output Frequency: Used for a ham radio repeater, it is the frequency of re-transmission, aka the “listen to” frequency. This scenario is obviously undesirable. If there are several groups of users on one radio frequency, CTCSS mutes users who are using a different CTCSS tone or no CTCSS at all. Geekprepper.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. F-Layer: The highest possible layers of the ionosphere, from approximately 90 to 250 miles high in total, that provide the longest propagation skips available with HF frequencies of 30 MHz or lower. A transmitter has two main components: an exciter and a power amplifier. This is generally performed by repeater stations in order to communicate between phones and two way radios. Magnetic Mount (mag-mount): Is a ham radio antenna that easily installs to a car or metal surface using a magnet. Repeater Directory: This is public listing of all repeaters. Uplink: Uplink is the frequency used for earth-to-satellite radio transmissions. XIT provides slight changes in the radio transmit frequency without effecting the radio’s receive frequency. Frequency Coordinator: An person or a group of people who recommend frequency pair assignments to repeaters in order to coordinate repeater use of the radio spectrum and also to avoid interference between repeaters. Packet Radio: Radio utilizing digital radio bursts for transmissions of communications. Pile–up: A pile up is when multiple ham radios attempt to make calls to the same station at the same time. I’ll keep watching this website. Repeater: A repeater is a radio station that receives a radio transmission and then re transmits the original frequency as a different frequency at higher power, or from a higher position. QSL: This is a Q signal (see Q signal) that stands for acknowledged receipt of message. We’ll follow up with a 2nd post showing you how to configure a TYT TH-UVF1 to do the same. the sideband is made of frequencies that are higher than the carrier frequency the transceiver is tuned to. Plain vs Serrated Edge Knife: What’s the Best for Survival? Hams and HAM Radio. It is a CQ magazine award for confirmed contact with each of the 40 world zones. Your email address will not be published. Then I can hear transmissions on the repeater’s output frequency. I’m not sure if this has anything to do with my issues, or how to add a column in the RT System to add rToneFrequencies. It's fun, social, educational, and can be a … Ionosphere: Is the layers of the atmosphere of the earth that is charged with particles that are induced by the rays of the sun. Field Day: An annual amateur radio event to practice emergency communications with other ham operators. Example: If the repeater output is 443.700 Mhz (70cm band). Picket Fencing: Picket fencing is when there is a rapid fluctuation in sound or a signal that is caused by a radio station that is moving during a transmission. Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. You can have the old reliable HAM devices, however, there are so many unanswered questions for the new HAM licensee. But we still don’t know how to use a radio (Baofeng). Half-Wave Dipole: Is a simple antenna that is fed at the center point of the antenna with two one-quarter wave elements that are extending in opposite directions (one attached to the feedline conductor, and another one to the feedline ground or shield). This radio information may be Morse Code, or it can be voice, digital, or other communication forms. 807: A deceptive ham term for ale and also a popular transmitting tube of the early 20th century. Antenna Gain: An increase in the antenna transmission and the reception performance in a particular direction with the expense of performance in other directions, performance will increase as compared to an isotropic antenna and a dipole antenna. Responsible for “Sporadic E” (see sporadic E) communications with frequencies above 30 MHz (which is especially for the 6 meter band). Q-signals or codes are a set of abbreviations for common radio information that can help save time and allow communication between operators who don’t speak a common language. Gray Line: The transition area line on the earth separating daylight and darkness. The First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. -- Ham radio Q signal meaning "Is this frequency in use?" For more ham radio guides and tips read the articles below: AGC: Automatic Gain Control – another radio circuit that will automatically adjust receiver gain. Negative: On-the-air slang term meaning “No” or “Incorrect”. HAM RADIO TERMS GLOSSARY This is glossary contains general definitions of typical amateur radio terms. I’ve not been able to find out how to set the rToneFrequency. Zepp Antenna: An end-fed wire radio antenna that is reeled down and up from Zeppelin aircraft. Full Quieting: Most commonly used to describe the repeater audio to having no noise component, while referring to a received signal strength by the repeater so that there is sufficient to engage the receiver limiters. ADIF: Amateur Data Interchange Format, a standard specification for the format of exported logbook files. 73 - Best regards, a greeting sent by radio amateurs over the air. Ham radio, also known as amateur radio is a popular hobby among most people in America. Traffic: Traffic refers to a radio message that has been distributed over a net. A repeater is just another two-way radio. Eleven Meter Band: The specific radio band in which citizens radio (CB radio) channels are found. NVIS is typical on low HF radio bands which are (40m, 60m, 80m) where horizontally polarized ham radio antennas are then raised to much less than a half-wavelength above the ground. 2 meters (~144-148MHz)* 2. If you can’t reach anyone, then you may have to take things to the next level and use a repeater. USB: Stands for Upper Sideband. Glen Zook, K9STH, posted this to the Heathkit mailing list: Many amateurs already know that "73" is from what is known as the "Phillips Code", a series of numeric messages conceived for the purpose of cutting down transmission time on the old land telegraph systems when sending text that is basically the same. 3.)
