A conventional radio feature, in which you talk
through a receive/transmit facility (repeater)
that re-transmits received signals in order to
improve communications range and coverage.
Radio Frequency. A part of the general
frequency spectrum between the audio and
infrared light regions (about 10 kHz to
10,000,000 MHz).
The muting of audio circuits when received
signal levels fall below a pre-determined
threshold. With carrier squelch, you hear all
channel activity which exceeds the radio's
preset squelch level.
