    Ham Radio Glossary - An overview of amateur radio terms.

    Radio Regulations
    The latest ITU Radio Regulations to which the United States is a party.

    (radio amateur civil emergency service). A radio service using amateur
    stations for civil defense communications during periods of local,
    regional or national civil emergencies.

    Reflected power
    Non-radiated power dissipated as heat when the transmitter is mismatched
    to the antenna or load.

    Rain locker
    Slang for a bathroom shower.

    Remote control
    The use of a control operator who indirectly manipulates the operating adjustments in the station through a control link to achieve compliance
    with the FCC Rules.

    A system consisting of at least one transmitter, one receiver, and a controller, which receives a signal on one frequency and retransmits it
    on another frequency. Repeaters are typically located in high locations
    so that they have greater coverage area. They greatly increase a user's communication range since they can retransmit his/her signal across all
    of its coverage area. Repeaters are in geographically high locations,
    and are most commonly used on the 2 meter and 70 centimeter bands. See
    also "Simplex Repeater".

    "Radio Frequency"; typically used as slang for "Radio Frequency Energy".

    RF Burn
    A painful sensation felt when coming into direct contact with RF energy;
    can be dangerous when experienced with high levels of RF power.

    RF ground
    Connection of amateur radio equipment to earth ground to eliminate
    hazards from RF exposure and reduce RFI.

    Radio Frequency Interference

    Slang for Radio

    "Receive Incremental Tuning"; a common feature on HF radios that allows the user to slightly change the receive frequency while leaving the transmit frequency the same.

    "Readability, Strength, Tone"; a system by which a received signal quality
    is graded, and a signal report is given. "Readability" is judged on a
    scale from 1 to 5, and "Strength" and "Tone" are judged on a scale from
    1 to 9. "Tone" does not apply to a "phone" (voice) signal. A very high
    quality CW signal is "599" (pronounced "five nine nine"), and such a phone signal is "59" (pronounced "five nine").

    "Radio Teletype"; popular digital mode on HF

    Rubber Duck
    Also known as "Rubber Duckie", a flexible antenna normally found on
    hand-held tranceivers. Inefficient, but useable, and they don't poke you in
    the ribs too badly either! (thanks to WD5CTQ).

    Abbreviation for "receiver" or "receive".
