RST sported a new mode on S-band last night and having a go at recording to do some analysis later tonight.

Its cyclostationary components are very strong and of great interest to my research.

At over 750000km RST is about half way to the Earth-Sun L2 point.

Follow-up: the signal's origin is now confirmed. More interesting though — the 75bps waveform (S-4415/MS-110A) itself turns out to re-inject its full preamble every 120s, a modification not in the base spec.

Roman Space Telescope (RST) S-band emission. Command echoes on the transponder are fairly loud. The signal appears to be LHCP.

Cyprus HF traffic = DHFCS Akrotiri. That's the reflex attribution in utility monitoring community. But if, this time, it isn't Akrotiri at all? A post about a 75 bps STANAG-4415/MS-110A (not frequent) signal on 18503.0 kHz:
