I have an early Navworx box that's been upgraded a couple of times, and the last FAA performance report came in all good. However ever since I got it one thing has dogged me and that is that I DON'T SEE ALL THE ADS-B TRAFFIC.
Specifically I will be flying in radar airspace (class C) with RADAR GOOD on the display and ATC is calling out multiple airliner traffic within 5 miles, and I can SEE the airliners - but many if not most of them don't show up on the screen.
Other times I'll be flying where I know other aircraft are that have ADS-B out and some will show up, others not. Most notably, close-by aircraft (within5 miles) with ADS-B out will not be there or will suddenly disappear.
Just today I was entering class D airspace (KHIO) and there were 3 ADS-B OUT targets on within 5nm on the screen and showing N numbers, and they all disappeared at once. The dropout seemed to coincide with my descending below radar coverage, but why would I lose them if they're transmitting ADS-B out? Meantime other targets further away still showed up, and all status indicators showed green.
My performance reports are showing good with the exception that there are usually Mode-3A partial failures, which coincide with being partially outside or on the edge of full coverage areas. For example on today's flight showed was a 27% Mode 3/a failure which makes sense since I started from the coast where there's little to no coverage below 3000', and flew into an area of good coverage within the first 6 minutes / 20 miles.
