Dennis 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.
