I understand now. I'll consider your suggestion, but I think that it
would be easier for me to adapt my application to work with Stratux.
Thanks for the clarification.

UAT uses different modulation / preamble / message
length and framing etc. A Mode S demodulator on a different
frequency is not going to work; you need a demodulator
specifically for UAT.
The underlying modulation is BFSK so you could maybe use a
generic BFSK demodulator (or even rtl_fm) and build on top of
that, but you do only have ~2 samples per bit to play with on
a 2832 so YMMV.
Hi Oliver,
I know that the frequency is different and that messages
have other structures. I have created my own message parser,
so I was hopping that all is needed is just changing the
frequency in the rtl_adsb program or, alternately, the
ability to specify the desired frequency in the command
line.

Is it
possible to adapt rtl_adsb to receive UTAs on 978
MHz as well? I wish something like this was
included in the library as a binary for Windows.
UAT is an entirely different protocol with
different modulation and message formats; it does
not have much in common with 1090MHz ADS-B.
