Re: [Elecraft] K3 Front Panel Not Working

[HarrytheHam]

First of all let me say thanks to all those who've contacted me with
suggestions and words of encouragement.

Spoke with Dale at Elecraft (nice guy). Apparently #2737 suffered the
dreaded switching matrix failure and needs to be sent back for repair. I say
"dreaded" simply because it affects me and apparently has not been all that
common among other units. I've had two or three other hams contact me whose
K3 suffered this failure in the past (identical symptoms). Dale did not seem
surprised when I described the situation, so clearly Elecraft has dealt with
it before.

Off to Aptos tomorrow.

Thanks again,

Harry WE1X

Re: [Elecraft] K3 Front Panel Not Working

[HarrytheHam]

Well, I've reloaded all firmware about 6 times and even did a force firmware
load, but no fix. Connected the K3 to HRD and the available HRD controls
function with the K3. Consequently, I think this is a hardware failure of
some sort where the front panel buttons don't work and/or are incorrectly
mapped. Does not appear to be temperature related as the rig is powered off
then back on hours later with same problem.  What is odd is this happened
out of the blue. Rig was operating just fine Saturday morning and when I
returned several hours later (with rig still on) the front panel stopped
working. Guess it's time to call Aptos on Monday.

Re: [Elecraft] K3 Front Panel Not Working

[Don Wilhelm]

Harry,

Do you have a recent K3 configuration saved somewhere?  If not, try to 
save the configuration using K3 Utility.
Then I would suggest doing an EEINIT followed by a new firmware load and 
a configuration restore.
Read page 65 of the K3 manual before doing an EEINIT so you will know 
what needs to be done if the saved configuration brings your K3 back to 
the same condition it is in right now.

73,
Don W3FPR

Guy, Thanks, but don't think that's it.  I installed the new firmware several 
days ago and the radio worked just fine. Even this morning it was okay. I took 
a 3 hour break and when I returned the buttons didn't function or function 
correctly. I've downloaded and installed all firmware 4 times. No change. Harry

Sounds like you got scrambled firmware.  Redownload the firmware. Then
follow the instructions on page 45 of the newest K3 User's Manual, in
particular the part about forcing a firmware download.

[Elecraft] K3 Front Panel Not Working

[HarrytheHam]

Upgraded to latest firmware the other day. All seemed to be fine. A few
minutes ago I noticed the macros that I programmed into the K3 were not
working. Then I noticed that if I pushed say the XMIT button the pre-amp
comes one. If I push the XFIL the "no DVR" message displays. If I push AGC
the "no MON" message displaysand so on. I cannot even get into the MENU
or CONFIG menus.

Any suggestions?

thanks...Harry WE1X

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

Re: [Elecraft] K3 Front panel not working

[Nick Verbeek]

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

Nick,

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

[Elecraft] K3 Front panel not working

[Nick Verbeek]

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
