frequency range from 117.9750 to 136.9750 MHz, with tuning increments of 25 and 8.33 kHz. A
channel spacing of 25 or 8.33 kHz (receive only) is assigned automatically by channel entry. The
URC-200 aviation mode channel entry is based on ICAO Annex 10 to the Convention on
International Civil Aviation, Volume V. Refer to Table 18, Aviation Mode Frequency Chart.
Aviation Mode also restricts modulation to AM, and allows PT only, disabling the CT feature of
the radio.
