I received one of the first batch of Classics, and had it fired up and working in 15 minutes with no problems. I'm using it with SkyDemon.
I used it in anger for the first time on a trip to Berlin and back this weekend. On the way out there, it worked just as I expected, picking up lots of targets, both Mode S and ADS-B (I'm not aware that I've spotted any PAW targets yet). However, coming back over the last two days, its performance has continuously degraded to the point that even after opening up the sensitivity and removing the height filters (on SkyDemon as well) I'm seeing nothing.
The ADS-B receiver USB module seems to be getting quite hot, compared to the other plug-ins and the unit itself. I was using a short power lead supplied with an Easyacc rechargeable battery pack to start with, and have tried again with the supplied lead to no avail.
I let the whole lot cool down and tried again off the aircraft, and as before it is seeing no targets. The 'traffic light' block remains resolutely red, all others being green, and the Traffic page is empty.
Any ideas, or have I just got a dud ADS-B unit which needs replacing?
