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.
You might want to look at dump978:

there's no Windows build)
