Jim,
DIGOUT0 is the only unambiguous signal with that information.
If you read the top right column of page 19 in the K3 manual (or page 21
of the K3S manual, you will see that AUX IO pin7 (XVTR ON) could also be
used, but if you use TX INH or plan to possibily do so in the future,
that same pin is dedicated to TX INH.
Don't forget that when not active, DIGOUT0 has an open drain driver and
must be provided with a pullup resistor in your decoder box.

Am I correct that the only indication that a properly setup transverter band is
being accessed is if DIGOUT0 is active low.
Put another way DIGOUT0 active low is the only way to know if the BANDx lines
on the AUX connector are signaling XVTR instead of HF.
Correct?
