[Eric] I believe the current UCB form requires the form to be opened and
THEN a band change for the FlexWire code to be sent.  This is inconvenient,
but it is what it is as this was a hack to make the FlexWire UCB prototype
functional.

[Eric] In the latest branches, we have tested the TX Out functionality
timing and it appears to work as intended in our testing.  Are you using the
Expert Antenna Form mode?  If so, are you setting the band to VHF3 or VHF4
to setup the TX1/2/3 outputs and delays?  If you'll send me your settings,
we'll see what we can do to replicate these in our lab.
