I tried SD today with a Rosetta PAw, using GDL90. PAw connected to the audio panel, SD sound connected via tablet / Bluetooth to my headset (with a different voice).
The runway annunciation and airspace warnings were great. GPS traffic worked fine.
There was 'traffic' target in the tower, a base station I think, but SD thought it was an aircraft and warned me of it while PAw ignored it.
I prefer to also receive the bearingless targets that PAw provides.
Any chance that SD could add that as an option? Then I would only need the SD audio into my panel. Otherwise it gets complicated, or I have to use only PAw and lose the airspace / runway stuff. I don't need rings when the targets are announced.

I use the GDL90 protocol with PAw with 2 SDRs, so the weather can be received aloft. My weather tab shows the red dot. I just need to fly over SD HQ or Redhill to get an update. I'll let you know.

SD rocks, thankyou
