Did the KPA500 show an asterisk (*) when key down? If not, it's not
seeing the PTT actions (key out).
If the KAT500 is content with the match, you'll only hear one fast
kerchunk of the relays (test, happy, shaddup). If it's not trying, it
may not be seeing the PTT and/or RF. (Has the K3 transmitter been
calibrated lately?)
Reseat all the cables and verify the settings in the KAT500 for 10 meter
operation (antenna choice); over time some minor corrosion can appear.
And make sure that the tuning output level of the K3 is set at 10-25
watts (and shows output too). Mine was set at 10 watts and consistently
worked (now I use a K4, KPA1500 and a much better antenna, no tuner needed).
If CW, was VOX on?

I have a K3,KAT500 and KPA500. I had a station on 10 Meters this
afternoon that I wanted to reach.
The KPA500 did not work on 10M as if it was in standby mode (it was
not), the KAT500 tuner didn't tune either the K3 showed 1.0-1 5W all
across the 10m band but no relays clicks in the KAT500. I tested after
this happened and both work as expected on all other bands. It has
been years since I used 10M. The firmware is current on all three units.
Any thoughts or ideas.
