Pre-takeoff checklist
I fly with the free open source Avare app (yes I donated) on my cheapo old 1st gen Nexus 7 with backup copies on my two S4 phones. It's so handy, the GNS430 and an old handheld aviation GPS now serve as tertiary backups. Last year I bought a $10 "thumb drive" SDR (DVB-T for Euro TV) on Amazon and downloaded the free version of the ADSB Receiver app that works great with Avare. A few minutes after the tiny SDR arrived at my house I was watching airliners on 1090 flying over the RZS VOR on one of my phones. Pretty cool, but after flying it I decided not to bother using it in flight. What I needed is all the UAT goodies (TIS-B, radar, METARs...). Still rare to see ADS-B Out below the flight levels here, but in LA hopefully the airliners' Out would trigger full UAT traffic radar display where I'm flying.
Recently a free open source app for Linux called dump978 (described in simple terms here using a complex $114 home brew setup on Foreflight) was released. Now the ADSB Receiver app developer is apparently adapting that or similar application code into his simple $2.50 app, to provide both 978 UAT & 1090 air to air on a single SDR for Avare.
If/when that happens the result will apparently be a complete ADS-B In solution (978 UAT & 1090) for a total cost of (far) less than $25 for hardware (including cables) and software. It should be simple plug 'n fly as it was for me with the same basic setup for 1090 last year. If you're a hw/sw techie, you can apparently do it now with rPi for $114 on Foreflight, and reportedly on Avare too.
So three questions come up for me:

So three questions come up for me:
- Are you keenly interested in this as I am?
- Do you know of another <$25 solution for moving map ADS-B In?
- If you have UAT and not ADS-B Out, are you seeing all traffic in a Class B like the LA area or mostly just the TIS-B rebroadcast of 1090 air to air?
