ANT1/ANT2 Auto Switch works on Maestro or SmartSDR, not via CAT

FLEX-6300 CAT band change does not trigger RX/TX antenna auto-switch.

I have a FLEX-6300 with RX/TX antenna settings on slice A and configured as:

  • ANT1 = 10–160m
  • ANT2 = 6m

When I change bands from the SmartSDR or Maestro, antenna switching works correctly:

  • 40m to 6m = ANT2
  • 6m to 40m = ANT1

When I change bands via CAT (using Logger32 or WSJT-X or N1MM or QARTEST ), the RX/TX antenna does not follow band settings:

  • 40m to 6m stays on ANT1
  • switch manually to ANT2 on 6m
  • 6m to 40m stays on ANT2
  • switch manually to ANT1

So I must manually change antenna each time I move band with any CAT.

Is this expected CAT behavior (frequency change only, no full band-change event for ANT logic), or is there a known setting/fix ?
