Having now added a PA system to the aircraft, I'm seeing some great results with SkyDemon producing aural alerts for traffic. The one main issue I have is when joining the circuit, it just won't shut up. Today, I also had it warning about traffic at the hold when I took off. This can be very distracting and has had me shouting at SD to shut up, followed by trying to yank out the audio cable.

Would there be a way of adding a filter so that (say), it doesn't display any traffic warnings below a set value? I'd probably set mine at 1500ft AGL for example.

Makes sense, since it's not all of these aircraft.  Mostly gliders, which are lined up waiting to be towed.
