So here's SdrDx 2.16y beta copying RTTY directly from radio station WLO, transmitting from Atlanta, GA. SdrDx can do SITOR B as well. Running 50 KHz bandwidth here, with the span set to 10 kHz, and the FSL demodulator set to 1.5 KHz, while tuned to 8474.5, which puts the center of the signal right at the 1.5 kHz mark. Demod bandwidth is 310 Hz, from 1310 to 1620. This is wide enough so that even with 100-baud SITOR-B (which WLO switches back and forth vs RTTY every few minutes) that all the sidebands make it through cleanly. I've got the spectrum and waterfall FFT set to 16384 buckets, which provides good resolution even on signals separated by only 170 Hz, as you can see here. I'm using my loop antenna with an AFEDRI SDR.
