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
