KAT500 antenna switching question - can't switch from ANT1

[K2PO]

I've had the KAT500 for years, but never had occasion to use ANT2 or ANT3.

I now want to put a second antenna on ANT2, but find the front panel ANT
button seemingly inoperative. The tuner stays on "1" regardless of pushing
the ANT button, and regardless of the AUTO/MAN/BYP mode.  I've tried with
the K3 on and off - same results.  Power cycling the KAT500 makes no
difference.  I've tried disconnecting both the XCVR and AMP control cables
- no difference.

I've tried with the Utility program.  Under the Operate tab I can click
ANT2 and ANT3 buttons, and the UI shows their selection briefly, but the UI
indication then returns back to ANT1.  (The KAT500, itself, doesn't seem to
respond to this brief selection entered through the utility program UI.)

The KAT500 has firmware 1.75.

Any ideas?

tnx,

Bill, K2PO

Fixed.  tnx to VE7ZD for the answer.  ANT2 and ANT3 were disabled under
Config tab.  Checking those boxes - and checking the box indicating All
Bands - did the trick.
