The 6EX can be buddy boxed with any of the Futabas that have the square "micro plug" but NOT and of the round DIN plug transmitters.
The DX7 can be buddy boxed with a large number of other JR radios and perhaps a few other brands IF you get the right trainer cord.
I don't think so. I bought the Futaba 6XAS PCM radio (w/R138DP - it was on sale for the same price as the FM R127DF Rx). Couldn't use any of the club's buddy boxes on PCM so had to go out and buy a new R127DF receiver. Buddy system worked fine. The older 6XAS TX was round plug. Newer 6EXA is square plug. So you not only have the shape of the connector, you also have the modulation to take into account.
Of course, had I had another Futaba PCM TX to use as my buddy box that would have also worked. Need all PPM or all PCM. Can't mix 'em.
He was asking about the 6EX 2.4 GHz radio. My answer is absolutely correct for that radio. THis fact is actually stated in the 6EX 2.4 manual. Mating to DIN connectors supposedly can cause malfunctions.
