K3 Spontaneous Failure
Locked
 
|
Tonight my K-3 failed after being on for about an hour when I was
away.It displays ERR EE2.When powered on again the same ERR EE2 is displayed.Tapping any button on the radio brings up a different error message, such as DS1, FPF LOAD PENDING, BP1, LPF, IO3, IF1, and on and on.Firmware reload is not possible. I sent Elecraft a support message and will call Monday, assuming I will have to ship it for repair.Has anyone seen this type of failure?Jim W6YA ______________________________________________________________ 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 Message delivered to [hidden email] |

Jim,
The K3 manual downloaded tonight, on page 69 says ... ====================================================================================================================== ERR EE2 ============== External EEPROM read/write test failed ================ EEPROM may be defective (front panel). However, this message may also appear if power is turned off/on too rapidly, or if the power supply voltage “bounces” during turn-on due to inadequate regulation. If the power supply is not at fault, try re-loading MCU firmware first; then try initializing parameters (pg. 66). ======================================================================================================================== Hope this helps. 73, Ted, W2ZK On 6/5/2020 22:20, Jim McCook wrote: > Tonight my K-3 failed after being on for about an hour when I was > away.It displays ERR EE2.When powered on again the same ERR EE2 is > displayed.Tapping any button on the radio brings up a different error > message, such as DS1, FPF LOAD PENDING, BP1, LPF, IO3, IF1, and on and > on.Firmware reload is not possible.

Ted, thanks for the note. I checked the error list immediately after
the failure and thought about that EPROM failure as a possibility. The power supply is fine. The radio had been powered up and failed while I had dinner. I know there are some pin connectors to the front panel that could be the problem, but I don't want to attempt to pull it off, so will probably wind up sending it to the EC hospital for a general face lift in addition to the fix unless there is a simple fix. I doubt one exists.

I would definitely try pulling the front panel off an then reinstalling
it, possibly with a few drops of Deoxit on the pins. It isn't difficult at all, and I think it's worth a try. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 06/06/2020 7:33, Jim McCook wrote: > Ted, thanks for the note.

Thanks to those who responded with good suggestions. This morning I
turned it on and saw a different set of error codes, but there was audio. Powered off and on and saw MAIN freq display, but SUB had disappeared. More power off/on resulted in going back to normal operation. It has been fine for the last hour. Will try the re initialization if it fails again. It may be the pins on front panel as some have suggested. I hesitate to pull off the front panel, but will talk to a friend who assembled his K3 about that. 73, Jim W6YA ______________________________________________________________ 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 Message delivered to [hidden email] |

Hi Jim,
Simply disengaging and re-engaging the front panel connector several times will often resolve the intermittent connection temporarily. But it will come back... Send your radio in for repair before it becomes a hard fault. If you have the old unreliable front panel connectors, your radio surely needs some additional upgrades too. 73 Frank W3LPL ----- Original Message ----- From: "Jim McCook" <[hidden email]> To: "Elecraft Reflector" <[hidden email]> Sent: Saturday, June 6, 2020 2:11:33 PM Subject: Re: [Elecraft] K3 Spontaneous Failure Thanks to those who responded with good suggestions.

Sure sounds like dirty contacts related to the front panel. I would
NOT try re-initialization without being sure the radio is working as it should and reliably. One could end up with more than one issue to deal with and diagnose. 73 Bob, K4TAX On 6/6/2020 9:11 AM, Jim McCook wrote: > Thanks to those who responded with good suggestions.

Yes
Pull the front panel and clean pins with Deoxit and reassemble.

Good advice. Don't do EEInit unless you are sure you have a good
configuration backup. Given the state of the radio now, doing a backup might not give you good data. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 06/06/2020 17:32, Bob McGraw wrote: > Sure sounds like dirty contacts related to the front panel.
