[Elecraft] K2 VFO/ALC issues

[Mike Short]

I recently bought a used K2/10 and the S-Meter does not work. I am looking
at the K2 VFO/ALC mod and have a question about the 1N4148s that are added
to Q18.

This one has a 1N4148 installed on the bottom of the board anode to cathode
across D13, and no diode from Q18-S to ground. Was the additional diode
part of another mod? Seems to me that it would defeat the purpose of D13.
