Oliver Jowett oliver.jowett at gmail.comUAT 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.
