I’ve been experiencing an issue with my K3, and I’m wondering how to
troubleshoot it.
Here’s the symptom.
Often, when I’m trying to work a weak DX station, I’ll switch the sub receiver
off and on, so I can better hear the DX station, then to try and hunt for the
station he’s working.

John and all,
This is a problem caused by the "way things work".
The original K3 did not have pullup resistors on the band data lines
(correct by engineering practices, the pullup resistors should be in the
receiving device).
BUT as a concession to those band decoders did not implement pullup
I had difficulty with the Unified Microsystems BCD-14, i.e. the CMOS
inverter IC was overheating.
I eventually received the following advice from AB3CV, which I found to work.

Your 5KW example is RMS voltage and peak would be 707v. I am not sure how
much moderate SWR effect this value but clearly the 1000v Alpha Delta

The UM decoders don’t put 12V on the input side. They have optoisolators on
the input side that can be driven directly from the K3 without interfering with
