Sometimes the pushbuttons on the four controls to the left of the
main VFO knob get stuck. Tap and rotate these four controls and
everything will probably start working again. One of the factory
guys gave me that advice and it worked for me, about two years
ago. I bought replacements for the four encoder/switches (about
$2 each) but never installed them, because everything has been
totally solid ever since, and installation seemed like a PITA.
As I remember, it took about ten minutes of fiddling with the
controls until everything started working again.

Subject: [Elecraft] K3 Front Panel Problem
Elecraft List,
I haven't used my K3 for quite a while as I have been playing
with the KX3 (the K3 has been sitting on the desk totally
disconnected from everything). Now when I fire up the K3, none of
the front panel buttons and dual-purpose controls work, except
volume and VFO A. I thought maybe the menu parameters got altered
somehow preventing the firmware from operating correctly, so I
tried to do a parameter initialization. But that failed because
the Shift/Lo knob is not working (The other dual-purpose knobs:
Hi/Width, Speed/Mic, and Cmp/Pwr don't work either). Therefore, I
figured the contacts between the front panel and the radio had
become corroded and weren't making a good electrical connection
anymore. So, I removed the front panel and inspected the pins.
Everything looked normal and I put the radio back together again.
Still not working.
Anyone want to make suggestions on what else I should try? I can
communicate with the radio using the K3 Utility and I did
reinstall the MCU firmware, DSP firmware and front panel
firmware. None of that helped. I still think there must be a
communication problem between the front panel and the radio, but
don't know how to fix it. Suggestions? Thanks in advance.
73,
