Your own transponder will not show because PAW knows your hex code and excludes it. There is no benefit in seeing your own shadow following you around.
Ian, you are right that it won't show on your Nav Display, but mine (also ADSB Out) normally shows on the top line of the Traffic Table with a big strong signal in a red 'signal strength' box.
Stu,
The Traffic Screen is like a 'collection box'. All the live data received by the system is collected and held there while it goes through the filters with all the ADSB and P3i data plus only relevant Mode C/S data being passed to the audio and nav systems. This means that much of the data that appears in the traffic table will never make it past that stage. The traffic data drops off the table as it either goes out of range or in the case of Mode 'C' 'times out'.
I'm seriously confused by your lack of traffic though. My first thought was that your pod must be carbon fibre and is screening out the signals, but you have said this is not the case - if in
any doubt, it would be worth double checking this, remembering that your airband radio operates on VHF, which will be less susceptible to screening than the UHF 1090MHz and P3i signals.
You seem to have the filter for known position (ADSB / P3i) targets set to 40,000ft in SkyDemon, so should at the very least be getting plenty of CAT ADSB. Your first Home Screen screen grab certainly shows some received ADSB traffic which might just have been out of range on your nav display, hence wouldn't show up. The Home Screen shows that P3i is transmitting Tx = - so the GPS fix is OK, but no received (Rx) P3i signals. This isn't unusual as they can still be thin on the ground - or should that be in the air?? It would be a good idea to open up your Mode C/S filters in your Config Screen to say +/- 5,000ft, or even greater and change Mode C/S Detect to 'Long Range' to see if this brings in more bearingless traffic. You can always narrow them down again later.
Let us know how this goes and please post some screen grabs of your traffic page if you can manage next time out.
Hope this helps
Regards
Peter
