K3 reset/reboot
Locked
 
|
My K3 has lost its mind.
The K3 has been sitting off the operating table for a couple of months (sacrilege I know!). Tonight I hooked it back up and powered up and while the display looks ok, none of the buttons function as they should. Most of them do nothing, others are mis-mapped, i.e. Mode ^ toggles ANT1/2, Mode (dwn) toggles RX/ATT, XMIT turns the preamp on and off ..... Tried the Shift/Power Up trick to reset and no joy. Of course it doesn't respond to any serial communications.... Checked the internal coin cell and its ok ... Any tricks I'm missing? Hopefully not a trip back to the mothership. 73, Mike N4GU K3 #01710 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Try restoring an old configuration and/or upgrading the firmware with the
K3 utility from a PC. Sounds not so good to me though... 73, Thomas M0TRN On 24 March 2012 00:11, M. <[hidden email]> wrote: > My K3 has lost its mind. > > The K3 has been sitting off the operating table for a couple of months > (sacrilege I know!).

Does it accept any commands in the CONFIG menu? Thinking you might be able to reset one item at a time. Slow but.....
Probably by the time you get my message you'll have six other more helpful responses. This is an amazing group. Good luck!

A common cure for this symptom is that one of the buttons on the front panel might be stuck. Exercise anything that you need to push for a function and see if it might clear up.

Thanks for the suggestions, but can't establish serial communications with it and can't get to any of the menus from the front panel. It just toggles a few items with the wrong buttons.....

Pasted below is an exchange between myself and Elecraft on a
similar problem that I had. I exercised the four pushbuttons to the left of the main vfo knobs a few dozen times each, and it started working again. I ordered four encoders at $2 each, but the problem has not recurred, so I'm not going to mess with replacing the encoders. Dave Hachadorian, K6LL Yuma, Arizona Hi Dave, The most common reason for that to happen, is that one of the 4 encoders to the left of the main VFO knob is developing a problem with the push in switch that is inside the encoder. Often wiggling the encoders or pushing their knobs in several times will clear the fault. If it becomes persistent, the encoders will need to be replaced with new ones. And yes, sometimes it is just a front panel poor connection. You can do exactly what you said about pulling off the front panel and pushing it back in. If you have some DeOxit (Radio Shack sells it), apply a small amount on the front panel connector pins to help stave off moisture related corrosion and poor contact. -- 73, Gary AB7MY ========= [hidden email] Elecraft Technical Support On 9/26/2011 8:15 PM, Dave Hachadorian wrote: Hi, Last week, almost all of the front panel buttons on my K3 s/n 993 stopped working. I turned the rig off, and back on again. The POWER switch worked, but none of the other buttons worked. I tried to do a switch test, but the menu/config button didn't work, so I couldn't get into config. I tried to do an EE INIT, but the shift/lo button wasn't working either, so the EE INIT failed. I kept floundering around, pushing buttons, and then everything started working again. In the CQWW RTTY contest this weekend, the problem showed up again on Sunday morning, after working fine on Friday evening and all day Saturday. I gave the rig a good smack, and it started working for a couple of hours. Then it failed again, and couldn't be fixed by further smacking. Is there an issue with oxidation of front panel pins, where they engage the main board? Maybe I should partially disengage the front panel by 1/4 inch, and put it on again to clean the pins? Please let me know, because I absolutely need this radio for Sweepstakes CW in November. Thanks.
