[ICOM] 756 pro and ssb

[Adam Farson]

Here is an accurate PEP measuring method, if you have access to an
oscilloscope:

It has been my experience with the 756Pro series that if the radio delivers
100W CW, it will put out 100W PEP SSB with correct adjustment of Mic Gain
and compression.

The Po scale on the moving-coil meter is average-reading. The bar-graph
scale is a little better as regards peak-reading, but still not accurate.
The oscilloscope method is the most trustworthy.

Cheers for now, 73,

 I recently purchased a IC-756 Pro and it seems to work great on cw and
rtty, not sure about SSB. I'm using my Heil Proset, and the adapter without
the cap. I've set the bass to -2db and the treble
to+5 db, as some suggested. I've tried both the narrow and mid
compression settings. I just don't seem to be getting out. I can only get to
about 75% on the power out meter, ALC and compression seem fine. Using the
monitor function, the audio sounds ok. Is 75% typical to read on the meter?
If I inject a tone, I can get 100%. In using the radio, I just don't seem to
be getting out like I did with my TS-850.
Just asking if this is typical with an Icom, as with my Kenwood, I could get
near full scale power on voice peaks.
