What kind of transmitter are you using for manual control?
I assume you aren't using a ground station all the time...
I only ask because most new 'brand name' (JR, Futaba, Airtronics, Robbe) tramsitters seem to be 2.4Ghz. I know FM radios are still available on 36 and 40 Mhz, among others, but I haven't seen many used for a while with new aircraft.
UHF transmitters can be rigged on a RC transmitter as a module or through the trainer port, depending on the radio. DragonLink and EZUHF appear to work this way. (I haven't used any of these.)
