I am borrowing this K2. I have had it for 2 weeks. The owner just had it
back from elecraft for some issues.
It worked as advertised for almost 2 weeks. When I turned it on the other
day I got the INFO 80 message.
Looking at a few things I found that the +6 volt regulator had the output
pin not soldered to the bottom of the board. Re soldering solved the Info 80
problem. Now the receiver is dead dead. not a signal to be heard.
Using an rf gen, I can hear the signal loud in the speaker at all the
frequencies I used.. But still no signals anywhere with antennas connected.
I believe there is a problem in the IF string.
At the base of Q22 I see a 1mhz signal. I believe this should be about
4.9mhz. At the mixer TUF-1(pin 4) I see the Rx VFO 8Mhz signal ok but
on(pin 1) I see 1.0 mhz.Any help?
