[Elecraft] K3 Display Won't Shut Off
One should / must turn the radio off using the POWER button on the radio
BEFORE shutting off the power supply. Otherwise said, never turn off
the power supply with the radio on. Why? There is a PDI {Power Down
Immanent} circuit that saves the current data configuration in the power
down process. If the power supply is shut off first, the PDI event
won't happen.
I know it's your radio, use it as you choose, but don't be surprised
when things come up whacky.

Re: [Elecraft] K3 Display Won't Shut Off
VGA cables are incompatible with the KPA500 and KPA1500. You will need a straight-through cable. BUT, you also need some pins removed. The power pin of the K3 is not compatible with the power pin of the KPA500 or KPA1500, and will result in the problems you have seen. The cable is described in the KPA500 manual, rev E1 on page 45. I’m not sure where it is in the KPA1500 manual, but I would be surprised if we didn’t include the same table there. 73, Jack, W6FB Elecraft Engineering > On Sep 17, 2021, at 7:47 AM, Jim McCook wrote: > > Now I see what's going on.

Re: [Elecraft] K3 Display Won't Shut Off
Now I see what's going on. Originally I used the Elecraft cable between the K3 ACC and the KPA1500 and everything was OK. The K3 could be powered down normally. When I moved that K3 to a spare position, that cable wasn't long enough, so I ordered an extension VGA cable. This is when the problem occurred. Apparently the extension is the problem withh pin 8. Will see what Elecraft Support says. 73, Jim W6YA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Yes, Alarm and Remote Operations Settings.

[Elecraft] K3 Display Won't Shut Off
When I plug the ACC connector cable for the KPA1500 into my newly acquired spare K3, the POWER button doesn't shut off the backlight in the display or the P3 that's connected to it. As soon as I remove that connector or shut off the PS, it powers down normally. This doesn't happen with the other K3 using the same cable. All is normal. Looking in the archives I saw something about a D10 removal, but couldn't find the specific info as to where it is and what the access is. It was described as an early mod, but this K3 is a later version #6695. Any specific ideas where the problem is and how to fix it? 73, Jim W6YA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
