Jerry gave me the final clue to fully solving the problem. He told Randy in another thread about problem solving, that R136 is like a mic gain adjustment. I noticed in all pictures available, that pot was set exactly the same. So after changing the final PA and having to adjust the Bias lower for 100mA current draw, I thought this may need re-adjusting too. I kept saying that it doesn't seem to be generating a loud enough audio signal before sending it ?out to the final. So, I adjusted it while listening with the SW receiver and watching the watt meter until it was peaked with no audio distortion ever noticed, just no audio when turned all the way down clockwise.
I couldn't wait, so I brought up the Sedona Arazona WebSDR station and actually heard my voice coming in from Oklahoma. I was running 20V on the PA. The signal was weak but audible and visible on the waterfall display. When I came down off the ceiling I did it again but couldn't hear it again. This is consistent with my CW signal monitoring. You know, band conditions between here and there right now, kinda of thing. 40M sure was busy at that time.
?Possible PA low output problem. Problem SOLVED!?
Congratulations Tom, thanks Jerry, Randy helped too by asking Jerry the right question, and thank you everybody else except for the ex-parrot. I am surprised it worked that well with an antenna that had 4+ swr without the tuner, and 1.2:1 with a tuner I have noticed attenuates the signal both ways. I am probably going to put the original dipole back up and trim it for more than just CW.?
