Thanks for clearing up what conversions are, I never knew what they were. On the receiver there is an F sticker on the back and a small round white sticker that says 75 MHZ BAND and both TX and RX are on the same channel (45).
It defenitly does read 75 MHZ. It sounds like 75 MHZ is not for aircraft is that right because that would be the problem right there.

thanks againm, chris
