I live in Orlando Florida and use an RTL dongle with Raspberry Pi to feed 1090 ADS-B to FR24. A lot of the local flight schools and GA traffic use the 978MHz UAT (US only) to transmit ADS-B Out. The FAA retransmits these position reports on 1090 so that other aircraft may see them. Has anyone successfully hacked their system to pick up and decode these retransmissions to see this extra traffic? Thanks.

I'm using the following command on my linux box with an rtl sdr dongle
Code:sudo rtl_sdr -f 978000000 -s 2083334 -g 48 - | ./dump978 | ./uat2esnt | nc -q1 127.0.0.1 30001

From a post over at Flight Aware (is it cool to link to the competition?):
I’m a little confused on what information is on 978 Mhz in the US. Will general aviation broadcast ADS-B on 978 Mhz? Also I was wondering if is it possible to decode TIS-B traffic to plot like we are doing on 1090? Thanks for the information.
obj (the creator of dump978) says df17 and 18 use the same encoding format. I modified the uat2esnt program to change the df type to 17.
quick runs with test data pumping it to VRS show the ADSB payloads are all valid as DF17. I'll try to get live data captured over the weekend and report backFeed Provider:

Europe & Other Countries used 50 Hz / 220 V or 230 V. USA use 60 Hz 115 Volts.
Transformers designed for 60 Hz cannot be used for 50 Hz ( even after change the setting to 220 V or 230 V ) - they overheated due to excessive "iron-loss" heat.F-WSSS1 - Cats refused to Pee & Pooh on RadarBox - Running a FR24 Receiver & DVB-T Dongle 24/7 to piss off The Chief Thief.

I added a --df17 flag to the uat2esnt program.
Can you upload a capture of your dump978 frames? I would like to see if you are getting TIS-B messages. These would need to be filtered out before uploading to FR24
