Thank you Byron for your answer.
I tried to set the alc pot, it seem to be OK. By rotating the screw both
clockwise and counter-clockwise on low bands, the power level change
accordingly, so the ALC red led. I also tried to set the power pot and
the power output changes. But the weird thing is the different behaviour
on higher bands (from 40m on), moving pots do not solve the problem, the
power output does not increase over 30-40W. This happens only on SSB. On
CW both power and ALC are just fine.
I also performed both master reset and ram clear, but nothing changed.

Hello
I had a Orion that had funny power It might work then it would drop power down
to 10-20watts . Dirty or bad alc pot. I cleaned the alc pot and worked fine
for two months then total drop off of power . Replaced pot back to working.
Adjusting power on the Orion isn’t the easiest thing to get right. Don’t remember the
the order of adjusting but mine didn’t like running 100 watts at that setting it would go to 130-140
watts on some bands . But set it at 90 watts and it’s rock solid on all bands.
Why???

My Orion does not handle the audio input correctly on several bands. By setting the full
power, on 160 and 80m it is OK, but on the others the ALC led does not light and the
output power is about on 20% (30% on 40m). The issue is present both on MIC and AUX.
Increasing the Speech Processor or the mic gain does not help. On CW mode all bands are
fine with full power output.Last year, the radio did not work at all, but by following
Bill (N4LG) and Gary (W0DVN) suggestions, I changed all the caps of the A9 board and the
radio was reborn. But I did not check the audio input, as I use it mostly on CW and low
bands. Now, I would make some QSO on the CQ WW DX SSB contest and I have got the
"surprise".Any help will be really appreciated.Best 73 de Enzo, IK3SWB
