Good Afternoon Gents
Many thanks to Al, Ken, Bill and others
The problem with the mic has now been resolved, it was a combination of
duff transistors, wrong transistor (Q1) fitted and the usual dry joints,
strange that many components were standing proud of the PCB, when I was
doing the suggestion of desoldering R15 the other end of R15 swung
around in the solder pad.
So I replaced or refitted all of these components and the voltages
appeared correct, still no audio from the mic, so retuned the 9mHz caps
c1 to c3, the adjusted the carrier balance, partial success, no tx on
ssb, now for the mic, checked both mics for O/C, nope not that, then I
remembered that the connection next to terminal 42 was reversed, so I
did that and it was sorted.
Attached my Step-Pir vertical and immediately started to resolved CW but
no matter how strong the signal the (G)uess meter just twitched, so
that's the next problem to deal with.
Adjusting the zero pot made no difference, going to check the voltages
tomorrow.
Unless in all of the knowledge that is out there somebody has met this
problem and resolved it.
thanks once again to all
stay well and healthy
