reported earlier A-10 C II UHF radio

[scopewizard]

Since the installation of the ARC-210 V/UHF radio in the A-10 C II, it is not possible to use preset frequencies with the AN/ARC 164 UHF only radio (Middle radio) as when the radio controller in in preset mode the dialing knob do not change the frequencies.  However, you can use dial frequencies and use the radio in manual mode.
