KPA 500 glitch

Having a bit of trouble with the KPA500 following the bands out of the
K3S. For some reason, the other day I accidentally hit a button
combination on the K3S (not sure what I hit) and the KPA500 is now
thinking 7.0 MHz is 1.8 and some of the other bands aren't switching
correctly either. I can't find the command or whatever might cause this
in the documentation I have. It's been working properly since I got it
some years ago.

Anybody have any ideas before I call Elecraft and bother the busy
support staff?

Thanks,

Jim Sheldon, W0EB

Jim,

I would suggest doing a Direct Frequency Entry into each of the ham
bands - no guarantee, but it has a chance of setting things straight.

Jim;

Check the AUXIO cable to make sure it connects to the K3S and the KPA500 (or KAT500) properly. This sounds like the Band1 signal may not be making proper contact.

The KPA500 watches the K3S’s Band signals for its band selection when RADIO is set to K3. If doesn’t see the combination for a band, then it will select the wrong band.
It is possible that the K3 is outputting transverter band info, but since it changes with HF band, it doesn’t seem likely. The cable issue seems most likely at present. You might
remove the connectors and make sure no pins are bent and that the pins are making proper contact.

Re: KPA 500 glitch

I ran into this exact issue caused by cable connections, specifically
the Y-cable that didn't allow the connector screws to join the cables.
Getting the Y-box from N6TV solved the loose cable problem.
