If you're referring to "Amateur" i.e. "ham radio" packet radio than yes, 
I'm told that it works great i.e. half-duplex -> large data -> short ACK.

Heh heh - I once ran *raw* Xmodem over packet i.e. not encapsulated in 
that protocol-from-hell AX.25 i.e. technically illegal[*]; it worked great 
until a packet was lost (the "hidden transmitter" problem) and the various 
timeouts concerned (Xmodem vs. the TNCs themselves) went completely 


Stuff the legality; isn't Amateur radio all about experimentation?  But we 
did announce on that frequency that we were about to conduct an 
experiment.  And whoever designed AX.25 (yes, I have studied it in great 
detail) must've been on something at the time...  Protocol layers? 
What's that?
