Re: CW key sticking with Nextion LCD — FIXED
So it’s looks like I got to the bottom of the problem where RF seemed to be getting into the delay of the CW and causing chattering in my auto tuner plus a hiss in the speakers.toggle quoted messageShow quoted text
It was due to the IF out pan-adaptor wire I installed and when the wire In rear was plugged into SDR it seemed to allow RF to get in. I also changed the resistor I was using as a buffer and replaced it wit a 22pf. It seems not to effect the circuit better then the resistor.
Anyway I added 3 ferrites to the coax piece from my tap to the BNC connector on then back of radio. It’s doing a good job keeping the RF out, that’s what it needed. I also went through an exercise of replacing all wires with shielded cables, which all helps to keep the RF gremlins at bay.
I ordered some small ferrite rings to wrap any misc single wires but my problem seems to be resolved.
