K3 err msgs on powr up?

Hello,

I have been away for 3 months. The K3 was completely disconnected from
antennas, power supply, including removing the PP from the back of the rig.
Today I decided to update the firmware and when I turned the power on, I
got err BP1, then LPF, IO3, IF1, XV3, AT3, PA1, and BP3. After that, it
worked fine. I hooked it up to dummy load and got full power on all
bands...turned it off, same result, BP1, LPF, etc. I could use any of
the rocker switches/buttons on the front panel and any of them would
cycle to next error msg, in the same order as the first time..then work
ok. I had an older firmware so decided to put 4.39 in the radio, along
with the DSP1/DSP2. AFter the successful download, same thing....power
up....BP1, LPF, etc.

Any ideas, suggestions?

P.S. K3 #250, factory built...3 times back to the factory, so far....

Replace the memory back-up battery ... it's probably dead and you
are losing the configuration each time you remove power.

Re: K3 err msgs on powr up?

I was under the impression that the battery is only used to power the
real-time clock, and config is stored in EEPROM/flash.

If I was Tom, I'd try the "EE INIT" (page 66 in the manual) and see
what happens...

In reply to this post by CX7TT

Could be intermittent contact between the Front Panel module and the
RF board. Try loosening all the screws on the FP module, backing it
out 1/8th inch or so, then plugging it back in.

Re: K3 err msgs on powr up?

I have K3 #145 and this problem has plagued me plenty in the past. I now know it *is* a problem with the FP connections as Wayne describes. I've more or less stopped it by using Deoxit on the pins; clearly there is an issue with oxidation(?) of the pin surfaces.

BTW, Jorge states the radio performs normally even when the errors appear. Have you checked for example that the KAT3 works when Err AT3 appears, and that you get 100w out when the PA error appears? Mine certainly didn't.....

We switched to all-gold plating on the mating connectors in production.

Recent firmware releases allows continued operation even if error
messages appear. The problem should be fixed as soon as possible, but
sometimes -- like at a DXpedition or during an emergency -- the show
must go on.

Re: K3 err msgs on powr up?

Wayne,

Would you have an idea which SN, or at least the approximate date, the
cut-over to gold-plated connectors occurred? Did this include all
connectors, or just the front panel ones?
