Me too. It does do very well.

This is very apparent in my 920. AND, it seems to be worse on
10-20 meters, than it is on 40-160 meters.

I do not have this problem. I leave the monitor gain at 12 o'clock
I am using the speaker or the homebrew Radio shack headphones.

Mine does too. I have heard of a few others that does this as well. I
mind it as my fan is very quiet.

Same results with a dummy load and a Yaesu YS-60 (Which was
against a Bird). I cannot get more that about 87 watts peak.

I just tried this (I am fortunate to have resonant antennas on
Guess what? Mine drops between 5 and 10 watts depending on the band!

Sorry, I don't hear anything....Hmmm
Lets hope that they come clean and repair all these bugs. I
immediately found 
the lower power output, as it wouldn't drive my AL-80 to full output
(Which requires 
100 watts). I hope I don't regret selling my 990!
