K3 not turning off
Locked
 
|
My K3 (S/N 544) is no longer turning off properly....the 12v sense mod is done, any ideas for further investigation????
Thanks, Glenn VK4FZ |

I'd next try the remote Power Off command (PS0) via the K3 Utility. If that works and the power switch does not, then you might have a defective switch. 73, Bill |

Or you may need to perform the mod that fixes this issue...

He said right at the start that that mod had been done Brett.

All works OK now Thanks again Glenn VK4FZ |

I suspect that Glenn's K3 turns on OK from the front panel switch, like mine. Glenn Much of May 2009 was spent troubleshooting this exact issue with S/N 071: the inability to power down the K3 from the front panel. Power on is fine. I performed numerous modifications (including the 12v sense, of course), diagnostics/measurements, replacement of a surface mount component, and replaced the FP board twice, all as directed but without resolution. However, the K3 shuts off using the "PS0;" command from the utility program. Given that workaround, my decision was to postpone sending it back for repair to see if a solution appeared over time - maybe something I could do myself. Our problems may not be identical, but if you're interested please contact me off reflector for the extensive troubleshooting email thread. Elecraft support during the troubleshooting phase was excellent, as always, but some issues defy remote diagnoses. If I were willing to part with the beloved K3 for factory repair, the problem would have been resolved a long time ago! 73, John K1JD Date: Wed, 28 Apr 2010 04:55:17 -0700 (PDT) From: Bill W4ZV <[hidden email]> Subject: Re: [Elecraft] K3 not turning off To: [hidden email] Message-ID: <[hidden email]> Content-Type: text/plain; charset=us-ascii Glenn VK4FZ wrote: > > My K3 (S/N 544) is no longer turning off properly....the 12v sense mod is > done, any ideas for further investigation???? > I'd next try the remote Power Off command (PS0) via the K3 Utility.

I saw one case something like this when something was connected to one of
the back panel connections that provided enough voltage to keep the MCU alive (I think it's a 3.3V device) If you remove all the connectors from the K3 back panel (except the Anderson power pole +12V supply, of course), does the radio shut down reliably?

Dick
I removed every other option in the radio, including the RS-232 interface board, the PA and the sub RX. The radio still did not shut off from the front panel switch.
