[Elecraft] K2 VFO/ALC issues

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 additiona

Re: [Elecraft] Problem with K3 driving old tube amp

Sounds as though ALC from the amp is causing the transceiver to step power.   One should NOT use ALC from the L-4B to the K3. The ALC circuit in the L-4B was designed for exciters which did not have precise power control.   The use of ALC to control power in this configuration is likely to caus

I suggest using automotive primary wire, #10 AWG for power cables.   It is stranded with much finer / smaller wire than THHN and is much more flexible than THHN.    It does correctly fit the 30 amp PowerPole connectors thus no splicing is needed or as suggested. I also recommend not only corre
