    intended for communications with space stations or with other Earth
    stations by means of one or more other objects in space.

    EAS
    Emergency Alert System. Formerly the Emergency Broadcast System.
    A system where at first an attention tone is transmitted over all
    stations, add the second tone, followed with specific instructions
    regarding the receivable frequency in the local, regional, or
    national emergency. The EAS is activated during severe weather
    warnings, chemical spill incidents, dam breaks, etc. Previously
    known as the Emergency Broadcast System (EBS).

    EBS
    Emergency Broadcast System. See Emergency Alert System.

    EEPROM
    Electronically Erasable and Programmable Read Only Memory

    EHF
    (extremely high frequency). The frequency range 30-300 GHz.

    EME
    "Earth-Moon-Earth" communication; moonbounce; using the moon as a
    reflector to "bounce" your signal back down to Earth. For a complete
    resource, please see http://www.nitehawk.com/rasmit/ws1_1.html

    Note that for ARRL awards, you must use the LoTW to confirm your contacts.

    ERP
    "Effective Radiated Power"; the power supplied to an antenna multiplied
    by the antenna gain in a given direction (if the direction is not
    specified, the direction of maximum gain is assumed).

    External RF Power Amplifier
    A device capable of increasing power output when used in conjunction with,
    but not an integral part of, a transmitter.

    Extra
