K3 Front panel not working

Good afternoon.
I run my K3 on and off with TRX Manager. This is great software and works very well.
Last week whilst working on 80m (500W) I had some RF feedback which locked up the PC.
Quick re-start and all was working again with TRX Manager.
Then I noticed that the frontpanel of the K3 did not work anymore. That is all pushbuttons did not respond, or responded a different function. The rotary controls are OK (except the pushbuttons behind them).
With the PC disconnected, I tried a re-start, re-loaded the firmware, and parameter initialization (page 55 manual) but none of them restored the frontpanel operation.

Again the K3 works fine when connected with TRX Manager, but fail to respond to the frontpanel controls.

Has anybody have had a similar experience, and if so what should I do to restore the normal working.
Any suggestion is welcome.

Thanks and 73, Nick PA0NCV

Nick,

Did you try removing power supply completly ? Or do a reset/reload the firmware after you remove power supply.

Re: K3 Front panel not working

Yes I tried that as well laurent.
Power supply removed for few minutes and than holding power switch in for 10
sec, which forces the the firmware download.
No change unfortunately

Thanks for the suggestion

Nick

Re: K3 Front panel not working

Yuma,

Only thru TRX Manager can I get into SW TEST (as also my menu/config button
does not work)

AS the Shift/Lo and Hi/Width don't work either I cannot perform the Scn Adc
function.

Thanks for the suggestion

Regards

Nick

Re: K3 Front panel not working

Nick

You can send cat commands to simulate a "press" of an encoder. See page 17 of the programming manual (SWT SWH) commands.

For Shift/Lo it is SWT58 or SWH58
For WIDTH/HI it is SWT59 SWH59
