I'd still suspect the config settings, this test just showed that the
KAT-500 is doing well mechanically. The tuner is getting a signal from
the K3 telling it what band you're on so appears to be limiting your
options based on that band. You can repeat the mode/ant test with the
radio off, you should get the same results as with the control cables
disconnected.
In the utility, Edit Configuration, Antenna tab, go through each of the
band settings and enable whatever antennas should be available on that
band. If you've already done that and it still isn't working right, I
don't know where to go next.

Thanks for the suggestion. Good test.
It turns out that Yes, I can change antennas now on 50 MHz when I disconnect
control cables. Hmmmm.
I reconnect the control cables, and the symptom of not being able to change to
antennas other than antenna 3 on 50 MHz, returns.
So one conclusion: maybe not the KAT500 settings.
