I was hoping you'd see this thread. I also posted on FTE - there seems to be a lot of traffic there... Here's the link

Yes I do. I don't have AE, but my Aeroforce gives me some info. I checked my EBP against Baro with KOEO and they were a match at 14.

Yesterday I experienced a different issue. I attempted to switch to the Whisper and nothing happened. No change. I switched back to DD, then to Whisper again, still nothing. Tried HI, nothing. Then again... everything worked as it should...
