First: Intermittants like this must be checked into a 
dummy load.
If you can't get the radio to act up into a load, 
carefully check
the antenna.  The VSWR unit is a good idea, also check the 
big PIN
diode that switches the transmitter to the antenna.  I 
found that a
1N4007 works just fine here.  The original can do some 
really strange
things.   Dave  WA0ZZG
