Wanted to bring this up again as as far as I know it's still not
solved. I tried to recreate the problem on the bench tonight with no
luck. I had the stratologger adjacent to it, the 100mw 70cm BPS and
70cm Beeline beacon all turned on. The unit seems to perform
nominally, arming and transmitting APRS when turned on the with
antenna down, and not doing so when sideways. I can't think of
anything else that would cause different behavior in the rocket vs
sitting on my table (it's still mounted in the electronics bay, I just
don't have the glass coupler tube wrapped around it). Antenna
orientations, as far as I know, are correct (most recent flight was
programmed for antenna down and flown antenna down-previous attempt
before that was opposite).

Also, unrelatedly, is there a way to tell if there's continuity on the
A-D channels with the altimeter in a closed bay without a TeleDongle?

Thanks,
-Andrew
