Yeah good shout, will do a local flight next time without SD and just leave the traffic screen up so I can see what its picking up throughout the flight. It certainly gets ADSB when testing on the ground from time to time (going by the altitudes of hits, but as you say though SD I have filtered down to +/-2K ft so aircraft when flying could be either). Its this intermittent aspect that has me wondering if its working consistently in the air so if I have that screen up I should get an idea if its going up and down.
I was actually trying to test the Transponder connection on the old FW version of Transponder after this but it was a non starter as couldn't even get into the settings menu of the transponder to set up the new squitter with our reg. It just kept warning about no cradle therefore AC mode only
FW issue even here as do this on another AC and can get into settings menu without issue.
That's before even trying to get it to work with PAW so at moment it looks like no ADSB out and I have a brand new FUNKE squitter and USB connection lead for sale if anyone on here is needing one...
