[ICOM] 756 Pro III Problem

[Roger Marrotte]

I just checked the power out, this morning, for all bands on my new PRO III
(< 2 weeks old) and power was about 104 watts on all bands.

Evening Gents:
I thought that before I boxed up my rig and sent it back to Icom, I'd look
to the collective wisdom of this group for some help.  I've had my Pro III
since March of2005.  The output varies from a high of 90 watts on 160 meters
to a low of 68 watts on 10 meters.  Is this normal?

Lately, I have been experiencing a problem (only noticeable on CW) where
when I have the RF output full CCW, (maximum power) that more than not, I
hear a hum on the sidetone and the power drops to anywhere from 8 to 11
watts output.  Also, sometimes it does that for a moment and then just turns
off and I have to wait ten seconds till the rig comes on again.
Now, I've checked the usual suspects, tight grounds, lose coax fittings etc
and everything checks out.  I suspect the high SWR protection circuit is not
working correctly.
The only challenge is that this often happens when I have a flat SWR of 1 to
1.
Any help appreciated and hopefully, I sufficiently articulated the problem.
Thanks in advance for the help.
