756 Pro 2 Heat (Was: [ICOM] PRO2 vs. PRO3)

It sounds to me as if the biasing of the PA transistors
is screwed up somehow and idling current is way high.

Icom  SHOULD  be able to fix that.

Hi John, Mine is 4 years old with full output and runs
cool.  Not enclosed in a cabinet. Sits on top of my desk.
Had a newer one and had the same problems as you.

Good Luck.  Watt

I had a 756PRO2 for a little while, and found 2 things I
didn't like about it:

1. It ran HOT!  Left it on for an hour or so on receive
only and it felt like most rigs do after running RTTY
for awhile.

2. It wouldn't put out 100 watts on SSB.  More like 70
or so.  This was according to the PO meter on the 756PRO2.
The Icom 756 I had did 100 watts on SSB according to its
meter.  I know of one other local ham who had the same
complaint, as it wouldn't drive his amp to full output.
I suppose it is possible that Icom changed the meters
to an internal average output meter, but I doubt it.

Have these problems been fixed in the 756PRO3?  I really
like the looks of the PRO3 with its additional features.
