Those would be Inmarsat-C signals, used for marine services - messages to ships in the ocean, weather etc.

Up around 1544-1556 you'll see some more spikes carrying aviation data to aircraft. These are the aero signals broadcasting Air Traffic Control messages via satellite.

Thanks, I am aware that this is within the Inmarsat range. I'm more interested in the protocol/mode being heard.

If you put an lna on your setup those signals will scream. Those that know will get what I mean by "scream".

Will the patch antenna work with a SDRPLAY......
i use this patch antenna


with SDRPlay and a SDRDuo with built in bias-T.
works great considering $50 price tag for the antenna. Working on upgrading to a helix when I can. SDRPlay works great with decoding software.
