Default Low Cost Dual Band ADS-B Receiver

Andy, regarding doing a MUX of UAT data into a FLARM stream. While it would be nice to see UAT targets on my FlarmView, the question is: would an effort to accomplish this be worthwhile?

I spent a little time seeing if I could find the relative number of UAT boxes vs 1090 boxes. I found a 2014 estimate that said 33% of transponders were UAT, but I don't believe that. The RPi hobbyists using Dump1090 and Dump978 say they are getting maybe seeing 5 planes a day on 978.

I'm sure there are other challenges. I do think it would be useful to MUX UAT (and possibly TIS-B) traffic into a FLARM NMEA stream, but it has challenges. I'd take whatever FLARM provides natively first, add a transponder second and then see if I need anything else, like ADS-B Out, TIS-B, UAT, or FIS-B (for weather radar, TFRs, etc - but that's a whole new set of display challenges).
