Amateur rad… VE: Stands for Volunteer Examiner which is the person who issues license exams in the amateur radio service. 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. Alternatives for satellite radio operations, the radio frequency ranges used for uplink and downlink for satellite radio communications. Ticket: A ham radio slang term referring to an amateur radio license. 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. How the software settings differ from the BaoFeng settings using the RT Software. 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 … That would be a loop, and that seems really, really bad. 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. The Meaning of Codes: QRL: I am busy or the frequency is busy. He has been passionately pursuing all things emergency preparation since working alongside his grandfather as a boy growing up in the Midwest. The CTCSS tone acts as an access method required to activate HAM radio repeaters. 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. It is an award from the IARU and administered by ARRL. Thank you for your articles. VSWR: Stands for Voltage Standing Wave Ratio. At night it combines these into a single F-Layer. The exciter modulates the audio from the receiver while the power amplifier boosts the audio level so the signal can travel further. Say it with words. To become a radio ham, you must pass an examination. Traditionally, the beginning of every transmission used a simple tone burst to access the repeater. APRS: Automatic Packet (or Position) Reporting System. One frequency is for it’s transmitting frequency and the other is it’s receiving frequency. Based in Geneva, Switzerland, the ITU is a subsidiary agencyof the United Nations. You may get lucky and snag a foreign(DX)station. A margin of around 25 Hz can still get through and access the repeater. Receivers in base stations at remote mountain top sites are usually not adjustable remotely from the control point. 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. Negative Offset: Radio repeater input frequency (transmits to) is lower than the repeater output (listen to) ham radio frequency. 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. (40, 80, 160). Echolink: A voice over IP internet connection variety allowing radio stations and/or computers the ability to be connected together for inter communications. The code representing the letters consists of a series of bits represented by high and low voltages. Example: If the repeater output is 443.700 Mhz (70cm band). Ham radio also is referred to as amateur radio. Life’s changes mean new challenges and ham radio is no different. You can find a list of repeaters, nationwide in the ARRL Repeater Directory. That is usually not any more than a few hundred miles in total. Skip Zone: A skip zone, when referring to ionosphere skip propagation, is the area inside the skip zone but also past the ground wave propagation. WAZ: Stands for Worked All Zones. 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. Dipole: A common antenna, typically made of wire that consists of 2 segments: The first is attached to the conductive part of the feedline and the other is attached to the grounded part of the feedline. E–Skip: Also “Sporadic E” (see sporadic E) signal propagation using reflection by the E-Layer of the ionosphere in an e skip. 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. It is an ARRL award to confirm contact in all 50 US states. Sales, Supplies, and Service. Not all of the definition listed may apply to your specific model of radio. Repeaters are designed to not transmit noise and spurious signals. This is a unit utilized in order for a transceiver circuit to be used to tune the transmission frequencies in both reception and transmission. Offset: The offset radio frequency that’s separation is between a radio repeater input and it’s output radio frequencies. Repeaters are much more complicated and expensive to setup due to a whole host of factors. This means that you have the same channel for transmitting and receiving. Fred is the Ready Zeal owner and editor. Other meanings that may be used in other services do not apply. Sky Wave: A sky wave is the propagation of the radio emissions caused through ionosphere refraction. 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 … 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. This is a report measured in three digits that shows how well received a signal is. 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). Someone programmed it for us but we don’t understand what they did. Phase Modulation (PM): Phase modulation is when information is encoded into an RF signal. Also known as a clarifyer. 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. I understand the offsets. DXCC: is an ARRL award for confirmation of contacts made in a minimum of 100 different countries. 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. The First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. I feel the Red/Blue means something is not set up correctly. I have not been able to find out what Red/Blue means? Propagation: Propagation refers to the RF signals path of travel and how the RF signal travels. Open Repeater: A ham radio repeater that can be used by any amateur radio operator. I hope you keep having these webpages so more people will get interested. A repeater tone filters noise by adding a low-frequency audio tone to the voice. Tone burst was the first method used to access repeaters. It is a transceiver control feature that is capable of adjusting the radios frequency without having to change the frequency of the transceiver. 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. 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. If both groups use radios without CTCSS, they can hear all transmissions. Refract: This refers to the bending of an RF transmission through the ionosphere. Oscilloscope: An electronic test and analyzer tool that receives voltage and current signals and then displays a visual representation of variations in signals over time allowing for tuning and performance measurements. It also can refer to the circuitry that makes this function possible. It is because ham radio (or amateur radio) has many advantages. A transmitter has two main components: an exciter and a power amplifier. Rubber Duck: A short rubberized radio antenna used on a handheld radio transceiver. Duplex: A radio communication mode that allows simultaneous transmitting and receiving (on two different frequencies). My goal is to help you prepare for any SHTF, big or small, natural or man-made, that could impact you and your family. Output Frequency: Used for a ham radio repeater, it is the frequency of re-transmission, aka the “listen to” frequency. Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. Here are the Q signals most commonly used in day-to-day operation. 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. Despite these differences, the overall concept of how a repeater works and how it must be operated is generally the same. Also used in place of I copy and I understand. Megacycles: Millions or cycles per second; also megahertz M. Million hertz Meteor Scatter: Amateur Radio signal propagation made by reflection from short-lived ionization trails of meteors that are in the atmosphere. It prevents the receiver and transmitter from hearing one another by the isolation it provides. It operates strictly on the signal strength, such as when a television mutes the audio or blanks the video on “empty” channels, or when a transceiver mutes the audio when no signal is present. A phase is the 360 degree cycle of oscillation. World's Largest Supplier of Amateur Radio, Ham Radio, and Communication Equipment. 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. USB: Stands for Upper Sideband. 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). Gain: With antennas, there is an increase in the effective radiated power in a specific direction when compared to that of a reference antenna. And as they say, necessity is the mother of invention. We’ll decide to do this if enough people ask for it in the comments. NTSC: National Television System Committee – US standard signal for broadcast TV, also used for amateur Fast Scan TV. This feature is generally used in SSB radio operations. As the name implies, this component receives incoming signal. Or for an alternating current. The CTCSS tone acts as an access method required to activate HAM radio repeaters. Drop Out: When a radio station is transmitting to a repeater and has insufficient power to consistently break the existing squelch of the receiver and the repeated communication is noisy and broken. Then I can hear transmissions on the repeater’s output frequency. I would love to see more about the Yaesu FT-70DR! 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). These signals are derived from Morse Code. Ham radio, also known as amateur radio is a popular hobby among most people in America. It was initially commercial operators who made use of CTCSS. Standard offsets (amount of frequency change) and shift (direction of frequency change) are established by the FCC for the USA. Deviation is dictated by the amplitude of the audio input signal. 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. 73 - Best regards, a greeting sent by radio amateurs over the air. Modulation: Encoding radio information into a radio frequency signal. 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. LSB: Lower Side Band – the single sideband used tradition for bands below 30-meters. The repeater has an audio filter to extract the tone, and only if it was present would the repeater activate. Used in superheterodyne receivers used to produce the intermediate radio frequency. The duplexer separates and isolates the incoming signal from the outgoing and vice versa. This is called a “positive offset”. I’ll keep watching this website. The reading is a percentage of the speed of light. Most repeaters are “PL’ed”, due to the sheer number of radios and repeaters in their area. Common Ham Radio Q Signals Hams use three-letter Q signals on every mode and even in face-to-face conversation. Deviation: In Frequency Modulation, is the variance from the resting frequency of the modulated carrier signal. That all starts with younger ham radio operators bringing new ideas and skills to our hobby. Amateur radio and all other forms of radiocommunications are worldwide and the ITU controls and regulates the use of theradio spectrum. Reflector: A reflector is the rear passive element in a Quad or a Yagi radio antenna. PL and CTCSS are used to prevent a repeater from responding to unwanted signals or interference. The ionosphere is able to bend radio frequencies back toward the surface of the earth, providing the long distance, signal “skip.”. QSL Card: A QSL card is exchanged between radio operators that confirms their contact and establishes a record of their contact exchange. PEP: Peak Envelope Power – This is the signals average power level over its greatest amplitude peaks. Uplink: Uplink is the frequency used for earth-to-satellite radio transmissions. I noticed my BaoFeng had an rToneFrequency that did not transfer over to the new radio. Next article BSI – National Standards Body of the UK This radio information may be Morse Code, or it can be voice, digital, or other communication forms. Hams and HAM Radio. So the best prepping should include getting the second level amateur radio license in order to understand and operate more powerful, but also more complicated radio systems that use frequencies and output wattages that will allow you to transmit beyond the curvature of the earth/horizon. This occurs along a pipe that is created through a temperature inversion in the lowest part of the atmosphere. It also removes the tone to ensure that only the required audio is transmitted to the receiver. Repeater Directory: This is public listing of all repeaters. An SSB is a specific type of AM signal. They are not for use in casual amateur conversation. Plain talk that anyone can understand. Magnetic Mount (mag-mount): Is a ham radio antenna that easily installs to a car or metal surface using a magnet. This was done to prevent one group from overhearing another group’s conversations even if they share the same frequency. This channel should not be used to chew rag (talk) on, but only to sync up with another HAM. This is the National Simplex Frequency. Positive Offset: This is a radio repeater input frequency that is higher input than the repeaters output frequency. It uses just one of the two sidebands while also deleting the carrier frequency from radio transmissions. Though it originally went under a different name, the agencyhas been running uninterrupted since 1865. Split Operating: Split operating is when transmission from one frequency while listening on a different radio frequency. RST: Readability Signal Tone. It can be the transmissions from a transceiver that is greater than the bandwidth necessary for normal communications that causes interference. WAS: Stands for Worked All States. 1.) Depending on your license class, you can select any available call sign in the groups listed below. Is this series available in pdf fomat for us older slower page turners? Quarter-wavelength vertical antenna-- An antenna constructed of a quarter-wavelength long radiating element placed perpendicular to the earth. 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. Elmer: A moniker for an experienced and knowledgeable amateur ham radio operator who guides or mentors newer ham radio operators. If the output frequency (transmit) of the repeater < 447 MHz, then the input frequency (listening) is 5 megahertz lower.
