Hi Dan,
I saw the change you made to check for the presence of a serial connection. Not something I was aware of, obviously.
Defaulting _detect_23cm_unit to False (i.e. UX-910 not present) in this situation has the unfortunate side-effect that Model_Support.html shows only the 2m and 70cm bands as being supported. Would it be a problem to change that method to default to True instead, such that all three bands are shown as supported?
Thanks,
Martin.
