Hello,
#2469 lives again. I finally located a sig gen so that I could begin
signal tracing in the IF strip.
As I was beginning, I touched Q21 and the receiver came alive again. A
close inspection of the rx pre-amp (on or off, previously tested) showed
nothing obviously amiss. I reheated all solder joints in the area and
the receiver seems normal again.
In spite of my efforts to protect it, I suppose it is a consequence of
the rig often being near salt water and in tropical heat.
I will now re-install the KPA100 and see if anything misbehaves. If it
is still OK next month, it is going with me to OC-206.
Thanks again to those who emailed suggestions.
