Know this probably not a SD issue, but the answer may be out there.
Running SD on either iPad or android phone with SkyEcho2.
Bluetooth to a David Clark PRO-X2 headset.
So far, so good. Gives excellent warnings of CAS, ATZ’s and ADSB traffic. But the volume is too low to pick up warnings in a noisy C152.
Any ideas? Thanks for your advice!
