[ICOM] IC-706MKIIG Transmit Problem

[Paul S. Serio]

Gary,
The problem is on more than one HF band though I have not checked them
all. I have tried different power supplies, power cords and antennas. I
have not tried to duplicate the problem on a dummy load yet. I will hook
it to a dummy load and try all modes and bands to see if the problem is
specific to SSB and/or a couple of the HF bands. Thanks for your input.
Paul, N5PS
