Eleven Meter Band: The specific radio band in which citizens radio (CB radio) channels are found. 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. -- Ham radio Q signal meaning "Is this frequency in use?" Time–Out: When referring to a repeater it is the timer circuit that can be used to avoid extra long transmissions or what is called a stuck mic condition. Net: An organized, on-air meeting of multiple radio stations, often held at a scheduled time. Communication is very important during an SHTF. 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. As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. This signal should be strong enough for re-transmission. And now I’m bringing in HAM Radio 101 – Intro To Repeaters: We’ll start to answer these questions to make HAM simple. 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. We’ll follow up with a 2nd post showing you how to configure a TYT TH-UVF1 to do the same.

Tropospheric Ducting: This refers to VHF signal propagation over long distances. Amateur rad… As the name implies, this component receives incoming signal. The CTCSS tone acts as an access method required to activate HAM radio repeaters. As a radio operators we call ourselves “HAM” or “HAMS”. Coax: Coaxial cable, commonly used as feed-line between the transceiver and the antenna. Hertz: Cycles per second, the standard unit of frequency measurement. Also used in place of I copy and I understand. This channel should not be used to chew rag (talk) on, but only to sync up with another HAM. In devices such as two-w… For example, use as an oscillating radio wave’s electric and magnetic fields in use. The input, or the frequency the repeater receiver transmits on 443.700, but receives on 448.700 (+5 MHz offset). This is used for computer keyboard to computer keyboard communication. Includes the 70cm band and higher frequencies. Multimode Transceiver: A radio transceiver with the capacity to use more than just one type of transceiver modulation: With FM, SSB, CW, AM, Digital radio operations. Second, it is especially useful during emergency situations. Repeaters are not necessarily “high powered”, but always take advantage of elevation and better antennas and feedlines (as stated above). A margin of around 25 Hz can still get through and access the repeater. OSCAR: Orbiting Satellite Carrying Amateur Radio. Fred is the Ready Zeal owner and editor. 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. Hamfest: A ham festival or gathering that at which ham operators and commercial businesses meet, trade, and display their equipment or techniques. This scenario is obviously undesirable. The table below lists the most common Q-signals used by hams. The ionosphere is able to bend radio frequencies back toward the surface of the earth, providing the long distance, signal “skip.”. The duplexer separates and isolates the incoming signal from the outgoing and vice versa. One frequency is for it’s transmitting frequency and the other is it’s receiving frequency. Over: An over the air term said in two-way radio communications under noisy or difficult hearing conditions to positively alert the other operator of the end of your radio transmission, and return of communications transmission back to the other operators radio station. Say it with words. Also known as a clarifyer. Traditionally, HAM is the informal name for amateur radio operators. He has been passionately pursuing all things emergency preparation since working alongside his grandfather as a boy growing up in the Midwest. If there’s enough interest, we can discuss setting up the Yaesu FT-2900 and the FT-7800 for repeaters and tones too. 70 centimeters (~420-450MHz)** NOTE: UHF: Stands for Ultra High Frequency. You should make your connection then decide on an alternate frequency to communicate on so that you don’t tie up that high usage channel. Not as common today. I know nothing about Ham radios. Then I can hear transmissions on the repeater’s output frequency. An SSB is a specific type of AM signal. FMF: Frequency Modulation Foxhunt: Is a competition event in which hidden transmitters are sought with direction-finding equipment by competitors. Get your license — please. Spurious Emissions: These are signals from a radio transmitter that are undesired and outside of the tuned frequency range. The unit of frequency is measured is hertz. Splatter: Splatter refers to the interference received from stations on nearby frequencies. 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. While with transistors, the increase in the signal output of the transistor as compared to the input of the controlling signal. ‘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.’ But following the frequency requirement accurately always resulted in better transmissions. The example above only illustrates two co-channel users. Amateur radio operators call themselves "radio hams" or simply "hams." Life’s changes mean new challenges and ham radio is no different. NiCad: Nickel Cadmium, a common type of rechargeable battery. Hi Hi: A slang term used on the broadcast air is the short for laughing. That evolution is inevitable. This means that you have the same channel for transmitting and receiving. Filter: An electronic component or circuit that is capable of allowing the passage of certain frequencies while also blocking others. SSTV: Stands for Slow Scan TV. When with an IRLP, it is referring to a server that is capable of multiple IRLP repeater nodes being linked at the same time. Next article BSI – National Standards Body of the UK Each signal can be a question or an answer, as shown in the Meaning column. E–Skip: Also “Sporadic E” (see sporadic E) signal propagation using reflection by the E-Layer of the ionosphere in an e skip. D–Layer: The lowest layer in the ionosphere, it is approximately 25 to 55 miles in the air, that fades away at night and is usually very weak during the shorter winter days. An antenna is used to transmit and receive signals that go in and out of a repeater. 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. Ohm: Is the unit of electrical measurements for electrical resistance and electrical impedance. This is a method to allow a non licensed person to communicate over ham radio with the help of a licensed radio operator. 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. Primarily refers to packet radio operations. Silent Key: A term for a ham radio operator who has passed away. DSP: Digital Signal Processing – is a processing method of filtering and noise reduction, also otherwise modifying received signals done by converting received signals into the digital form for manipulations. This is measurement of the voltage sent from the radio transmitter that is reflected back from the antenna and feedline to the transceiver. Tone burst was the first method used to access repeaters. 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 … A phase is the 360 degree cycle of oscillation. And as they say, necessity is the mother of invention. J-Pole Antenna: is a half-wavelength radiating radio element with a quarter wave matching stub, popular on VHF and UHF radio frequencies and a popular DIY homebrew build. Accordingly, please follow FCC rules and repeater operator’s conventions for their systems for the betterment of all. ERP: Effective Radiated Power – the power that is radiated by an antenna. Sky Wave: A sky wave is the propagation of the radio emissions caused through ionosphere refraction. Well, it goes like this: The word "HAM" as applied to 1908 was the station CALL of the first amateur wireless stations operated by some amateurs of the Harvard Radio … It is an ARRL award to confirm contact in all 50 US states. Gain: With antennas, there is an increase in the effective radiated power in a specific direction when compared to that of a reference antenna. A repeater is just another two-way radio. I’ll keep watching this website. 1.) Think about it this way, if the repeater used the same channels for both transmit and receive, it would only hear itself. Hang Time: The brief continuous transmission of the repeater following the termination of a transmission to the radio repeater, and that is usually denoted by the terminating transmission of the courtesy tones. Driven Element: The portion of the antenna that attaches to the feedline. HAM RADIO TERMS GLOSSARY This is glossary contains general definitions of typical amateur radio terms. WAZ: Stands for Worked All Zones. 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. This is different than a mobile ham station which is designed specifically for use in vehicles. Responsible for “Sporadic E” (see sporadic E) communications with frequencies above 30 MHz (which is especially for the 6 meter band). Thanks a bunch. This is generally performed by repeater stations in order to communicate between phones and two way radios. I understand the offsets.

MUF: Maximum Usable Frequency – this is the highest radio frequency for given conditions that will provide the needed reflection from the earth’s ionosphere and will promote skip propagation between two specifically designated radio station locations. When not working on the family homestead he can be found brewing coffee and reading a good book or backpacking in the wilderness. When I transmit, my radio has a Red/Blue bar as I am transmitting. APRS: Automatic Packet (or Position) Reporting System. 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. 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. Negative: On-the-air slang term meaning “No” or “Incorrect”. How the software settings differ from the BaoFeng settings using the RT Software. This is called a “positive offset”.

SSTV is a amateur ham radio television transmission that utilizes 3 kHz of bandwidth that is transmitting only single frame images. Duplexer: A radio repeater component that allows a single antenna the ability to transmit and receive simultaneously by implementing a sharply tuned filter to separate the transmission and reception channels. A TNC allows interfacing with the transceiver through a control box. Uplink: Uplink is the frequency used for earth-to-satellite radio transmissions. At night it combines these into a single F-Layer. This is due to it’s short (small) antenna and it’s the fairly low height with respect to the radio horizon (unless you are on the side of a mountain). If both groups use radios without CTCSS, they can hear all transmissions. Layer: A layer of the ionosphere that is approximately 55 to 90 miles high and that typically fades away after sunset ocurrs. In this first post, we’ll walk through setting up a BaoFeng UV-5R to use a repeater with a PL or CTCSS tones. Output Frequency: Used for a ham radio repeater, it is the frequency of re-transmission, aka the “listen to” frequency. I’ve purchased a new radio and I’m a newbie…I am able to listen to a few repeaters, hear hams speaking with the repeaters, but I don’t think they can hear me. Selectivity: This refers to a radio receivers effectiveness at rejecting radio signals on adjacent frequencies. Ham radio also is referred to as amateur radio. You benefit from the repeater’s higher elevation, which increases your effective transmitting and receiving area! Learn more. Before it opens up, the receiver must receive a signal on its input or receive frequency. Refract: This refers to the bending of an RF transmission through the ionosphere. GOTA: Get On The Air – An annual ARRL Field Day event in which all non-licensed operators are provided an opportunity to transmit under that of the control operator supervision of a licensed ham radio operator. I noticed my BaoFeng had an rToneFrequency that did not transfer over to the new radio. XIT: Stands for Transmitter Incremental Tuning. I don’t even know the questions to ask. QSL: This is a Q signal (see Q signal) that stands for acknowledged receipt of message. Machine: a common reference for a radio repeater. 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). Tone Squelch tells the repeater to respond only to stations that encode or send the proper tone. This channel should not be used to chew rag (talk) on, but only to sync up with another HAM. Repeaters are designed to not transmit noise and spurious signals. Phone: When a radio encodes voice information from a transmission into an RF signal. 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. It is because ham radio (or amateur radio) has many advantages. 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. QSL card-- A postcard that serves as a confirmation of communication between two hams. This is due to it’s short (small) antenna and it’s the fairly low height with respect to the radio horizon (unless you are on the side of a mountain).

Frequency: The raw number of oscillation cycles per second of the electromagnetic wave. Welcome! The receiver is generally very sensitive and selective so the repeater can hear even the weaker stations. Paddle: A type of Morse Code key used to send morse code messages. I feel the Red/Blue means something is not set up correctly. S–Meter: An S meter measures the signal strength of received signals. Squelch: The squelch on a radio is the control for muting the audio of the transceiver when there are no signals being received. How to Use a Ham Radio Repeater Simplex Communications. 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. It is also commonly known as Coordinated Universal Time. Required fields are marked *. It also promotes an enhanced and higher propagation path for some RF bands. PEP: Peak Envelope Power – This is the signals average power level over its greatest amplitude peaks.

Earth Ground: is an electrical connection made to the earth, it is usually to a metal rod driven into the ground. The actual operation of a repeater will vary depending on several factors such as the country where it is operated, the band being used, and the make or model of the repeater. You can find a list of repeaters, nationwide in the ARRL Repeater Directory. But want to learn. Key: A switch, or lever, or even a button for sending Morse Code to receivers; referenced by a telegraph key. WhatIs.com. Both stations take turns transmitting and receiving on the same frequency with no repeater or other device in between.Duplex – Duplex operation means that a radio station transmits on one frequency and receives on a different frequency.Full Duplex – Operating duplex with the … Digipeater: Is a digital repeater capable of temporarily storing, then re-transmitting on the same frequency, of a digital packet. 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. On the 2 meter band, you can use 146.520 MHz. One sends QRL before calling CQ to determine if a particular frequency is in use. Double: On a repeater is 2 radio stations transmitting simultaneously. Continuous Tone Coded Squelch System, or CTCSS is a communications industry signaling scheme called the Continuous Tone Coded Squelch System (CTCSS). A repeater boosts your signal and receives the station you are talking to, over a far greater range and coverage area! It can both send and receive radio transmissions. Split Operating: Split operating is when transmission from one frequency while listening on a different radio frequency. The code representing the letters consists of a series of bits represented by high and low voltages. Barefoot: Operating a transmitter without having an amplifier so that the output power is produced by just the base transmitter. This was done to prevent one group from overhearing another group’s conversations even if they share the same frequency. 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. The VEC is an amateur radio organization that is coordinated along with the FCC to operate and oversee all volunteer radio examiners. This is a report measured in three digits that shows how well received a signal is. This is the National Simplex Frequency. This is called a “negative offset”. 4.) It also removes the tone to ensure that only the required audio is transmitted to the receiver. Field Day: An annual amateur radio event to practice emergency communications with other ham operators.
