EPIRB decoding #2257

Open OlivierTE opened 1 week ago

OlivierTE commented 1 week ago

Description of the feature you're suggesting.

Hello, in charge of decoding EPIRB beacons (COSPAS SARSAT), I carry out this task from traditional radio receivers and electronic decoders. The whole thing is heavy and tedious to transport. The portapack would be an easy to transport solution and probably very effective if decoding could be done directly in the software. Sorry if the feature already exists but I haven't found it. Being part of the official research teams, I can have a test beacon if necessary.

Anything else?

If you got an IQ file (c16) capture with portapack, you can attach it here (more is better!). That way if someone wanna look into it, it will be easier.

Hello, I ordered it yesterday on Aliexpress following your recommendations. As soon as it arrives, I will send you the file. Thank you very much. Have a great day. Olivier
