So, I have been turning my attention to the idea of buffering 24 hour grabs of all radio spectrum, using Web SDR. I'm just reaching out in case people are sitting on sets of these from times past. DM or [email protected].

Am I really to the point of archiving radiation? Yep.

The big concern is disk space. Under current approaches, a full spectrum grab of 24 hours of signal in one geographical location is ten terabyes! But one day a year might be worth it. For history.

@textfiles I love the idea. Maybe recording samples of one hour every month and storing the complete speech2text would be more useful (especially allowing indexing and searching).

@a I've begun discussing things with people who know better to see if compression is possible.

@textfiles @a it would be pretty hilarious if it ends up that you can just use, say, FLAC and get ok compression.

@kepstin @textfiles @a You actually can use FLAC to some extent. I highly recommend reaching out to the people working with ld-decode and vhs-decode, as that's their primary domain of expertise; RF capture + post-capture compression
