Radio checks are done after at least the start of the APU because both VHF radios require AC power, only the UHF radio works with battery. All TARS does is make the radios work as they would real world through TeamSpeak meaning you have to have the radio on and tuned to the same freq or reset.
Not close at all. Front/Mid/Aft is in reference to each radio and has nothing to do with moving the ACFT.
Front = VHF/AM
Mid = UHF
Aft= VHF/FM
