One other fun way of "demodulating " these tiny QRSS FSCW signals is by eye. If you access a KiwiSDR and observe the HiFer band when prop is good, and zoom in tightly, you can see the shift happening. It's not big and sharp, but you can see the shift occur sometimes. On the 13Mhz Hifer CW beacon signals, you can see the chirp on some of the beacons. It's fun stuff and there's a lot to learn about propagation by observing. I capture 10 minute grabs and 1 hour grabs on 10M and it's fascinating looking at some of the short openings that happen, in addition to those you might expect at grey line, etc. QRSSPlus is an interesting website to watch.
