Hi again, Werner:

I can't speak to what you might see on your LP100 meter. I know nothing 
about it except that is held out to be good! Since I have very little 
experience with SSB, I'd best not suggest what might be normal  :-).

I have a Diamond SX-200 wattmeter and in the Averaging position I see a 
max of about 45 - 50 watts and in the so-called PEP position I see 
anywhere between 60 and 90 watts indicated. That is with the Heil ProSet 
from Elecraft, mic gain set to 8, and Compression set to 16.

73,
Ken K3IU
