@Adam_AS_2 Hi Adam, for a quick technical reference would it be useful if future posts included a downloadable concise Fact Sheet? For example: https://disk.yandex.com/i/x_PMyBgMBezS4Q

@Adam_AS_2 Thank you! However, there is an oversight in my post, as I refer to 'CW MORSE' when it is actually 'MORSE-FSK'. I will fix it as soon as possible 😄

Analysis of a CIS Navy 50 Bd FSK intercept: the post breaks down standard transmission features alongside distinctive operational details such as a 700 Hz frequency shift and a CW Morse preamble signaling high-priority traffic.

Quick test of Skywave Web SDR. The server sends compressed IQ, your browser does the demodulation. Runs on a Raspberry Pi, tested to 256 listeners.

Right now it's playing an AO-40 pass I recorded 23 years ago on pi day 2003, with the @rfspace SDR-14.
