Thanks to everyone for the responses that I received. I've checked the
mic plug and it seems to be fine. It is now working again as before
but, it will probably stop working. Since it's been working, I've
checked the output on different bands. I switched from RF to ALC
display and noticed that on 20 meters and higher, the display shows a
maximum of two bars at most on voice peaks. On 40 and 80 meters, it
shows five to six bars on voice peaks. Each time it has failed I have
been on 40 meters. As Don suggested, it is as if it is over driving the
ALC and it is happening on 40 and 80 meters but, not the other bands.
Also I didn't have the jumper installed for pin 5 since I don't use the
preamp in the mic. This is the configuration it was originally in when
I started having the problem. Just out of curiosity, I installed the
jumper for pin 5. When I turned on the K2 all I got was "ELE" and
that's as far as it would go. I took the jumper back out, and the K2
comes up normally.
Another thing that I thought I might check is the soldering on the mic
jack on the front panel board. I remember having a bit of a problem
soldering it and I wasn't exactly sure of how I should solder it. The
jack will move a little when I screw the mic plug in. What I mean by
that is the entire mic jack does NOT move but, the eight pin assembly in
the jack will rotate about a sixteenth of an inch or so. As I remember,
I had a problem getting the solder to flow and I had to keep the tip on
longer that I wanted to. I should probably just replace the entire mic
jack if that might cause this kind of a problem.
Thanks,
