I had the same problem with a IC-737A on CT 9.34. CT could receive from
the radio but the radio was deaf and CT kept showing "radio time out"
notices. Dave's reply certaily are consistant with the symptoms.
But, I have used this 737A with earlier CT9' versions with no problems
and the 737A still has a 3CH address. Could it be that somehow CT has
messed up its table of models verses addresses? (Note how easy it is to
point my finger when haven't a clue <grin>.)
