Glossary of Amateur Radio Terms

  • 73
    • 73 stands for “Best Regards” So the answer the “which is the correct way, 73 or 73s?” question? The correct way is 73. As you can see the word Regards is already a plural form, so by adding the “s” after 73, it makes it a double plural, “Regardses”. Link to be added.
  • AM (Amplitude Modulation)
  • AMSAT (AMateur SATellite)
    • The Radio Amateur Satellite Corporation (as AMSAT is officially known) was first formed in the District of Columbia in 1969 as an educational organization. Its goal was to foster Amateur Radio’s participation in space research and communication. AMSAT was founded to continue the efforts, begun in 1961, by Project OSCAR, a west coast USA-based group which built and launched the very first Amateur Radio satellite, OSCAR, on December 12, 1961, barely four years after the launch of Russia’s first Sputnik.
  • APRS
    • Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area.[1] Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.
  • ARES
    • The Amateur Radio Emergency Service® (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment, with their local ARES leadership, for communications duty in the public service when disaster strikes.
  • Diddle Stick
    • This is the term used to mean non conductive screwdrivers and other tools that are used on electronics that plugged in and turned on. Some times you have to work on them when they are live. Like adjusting the deviation on an FM transmitter.
  • Elmer
    • An Elmer is the Ham Radio term for a mentor, a helpful Ham that provides advice, encouragement, and assistance to fellow Hams. Most Hams have an Elmer at some point to help them get started and guide them on their first steps in Amateur Radio.
  • Morse Code / Continuous Wave (CW)
    • Morse Code, either of two systems for representing letters of the alphabet, numerals, and punctuation marks by an arrangement of dots, dashes, and spaces.
    • The codes are transmitted as electrical pulses of varied lengths or analogous mechanical or visual signals, such as flashing lights.
    • One of the systems was invented in the United States by American artist and inventor Samuel F.B. Morse during the 1830s for electrical telegraphy. This version was further improved by American scientist and businessman Alfred Lewis Vail, Morse’s assistant and partner.
    • Soon after its introduction in Europe, it became apparent that the original Morse Code was inadequate for the transmission of much non-English text, since it lacked codes for letters with diacritic marks.
    • To remedy this deficiency, a variant called the International Morse Code was devised by a conference of European nations in 1851. This newer code is also called Continental Morse Code.
  • NIST
  • OM (Old Man)
    • Used as a term of respect in the amateur radio community.
    • An OM is a radio operator that has paid his dues and is respected by his fellow ham’s
  • PL Tone / Sub audible tone
    • CTCSS stands for Continuous Tone Coded Squelch System. Basically what it does is this: it adds a tone into your transmission at a certain frequency. Other radios must have the same CTCSS tone or code set to hear the transmission. It will also be heard if the radio has CTCSS and DCS off. Different CTCSS codes have different frequencies, and this is how it filters out other people – as long as they have a different CTCSS, or no CTCSS, then your radio will not pass any audio to the speaker. A radio with CTCSS enabled will only pass audio for the tone it has set.
  • Silent Key
    • When referring to a person, the phrase Silent Key, and its abbreviation SK, is a euphemism for an amateur radio operator who is deceased.
    • The procedural signal “SK” (or “VA”) has historically been used in Morse code as the last signal sent from a station before ending operation,[28] usually just before shutting off the transmitter.
    • Since this was the last signal received by other operators, the code was adopted to refer to any amateur radio operator who is deceased, regardless of whether they were known to have used telegraphy in their communications.
  • SWR (Standing Wave Ratio)
  • SWR and Watt Meters
    • Measures power out in watts and the SWR (standing wave ratio). Higher SWR is bad, as most modern radios will reduce their output if the SWR is too high, so it’s a good idea to monitor the SWR. They can also be used to tune your wire or mobile antennas.
  • The Amateur’s Code
    • The Radio Amateur is:
      • CONSIDERATE….. never knowingly operating in such a way as to lessen the pleasure of others.
      • LOYAL….. offering loyalty, encouragement and support to other amateurs, local clubs and the American Radio Relay League, through which Amateur Radio in the United States is represented nationally and internationally.
      • PROGRESSIVE….. with knowledge abreast of science, a well built and efficient station, and operation beyond reproach.
      • FRIENDLY….. with slow and patient operation when requested, friendly advice and counsel to the beginner, kindly assistance, co-operation and consideration for the interests of others. These are the hallmarks of the amateur spirit.
      • BALANCED….. Radio is an avocation, never interfering with duties owed to family, job, school or community.
      • PATRIOTIC….. with station and skill always ready for service to country and community.
  • Watt
  • Watt Meter
  • Woodpecker (Russian Woodpecker)
    • During the 1970’s and 1980’s, anyone who owned a shortwave or ham radio would have been very familiar with a sharp, repetitive “rat tat tat tat” noise. This interference permeated the airwaves and disrupted over air communications and television signals all over the world. This characteristic tapping sound gave the device(s) its now-famous nickname “The Russian Woodpecker” aka the Duga Radar system.
  • WWV
    • NIST radio station WWV broadcasts time and frequency information 24 hours per day, 7 days per week to millions of listeners worldwide. WWV is located near Fort Collins, Colorado, about 100 kilometers north of Denver. The broadcast information includes time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, and geophysical alerts.
