Raw input data for those without hardware

GNU Radio
1

I don’t have any hardware and am looking for some raw input data to
play with. It doesn’t really matter what. Where are good places to
find this?

I faintly remember people asking this question here before, but
haven’t come up with the right search terms to bring up those emails.

Cheers,
Ben

Ben,

Anything in particular you’re looking for? If you tell me what
transmission type you’re interested in, I’m happy to put up some
recordings, presuming I can hear it from where I am.

I’m wanting to have a play with gnuradio with some real data, rather
than make-pretend software generated stuff, but don’t have any
particular transmission type in mind. I thought there were a couple
of websites where people had uploaded some dumps of various things,
but perhaps I’m wrong.

To be honest, I don’t have a good idea of how complicated the common
transmission types are. I’d like to have a crack at something digital
but other than that it would probably be best to be as simple as
possible.

You might find something useful on CRAWDAD. Most of the datasets are
for higher layers, but there appears to be sample data in the RF
section.

Thanks. That list of example protocols was really useful. Now I’m
finding plenty of stuff.

There’s hundreds of different protocols that can be received with
ordinary general purpose receivers and input to Gnuradio via an audio
source block. As long as it fits into the bandwidth of a sound card, it
should be fair game, and because these narrower signals are more easily
received there tends to be more example data online in regular old .WAV
format. Some examples: PSK31, RTTY, SSTV, APT, AIS, ACARS, POCSAG (if
you can find it), the various trunking radio protocols, older MDT, lots
of satellite telemetry.

For higher bandwidth stuff, the offer still stands of course, I’ll be
happy to make a recording of whatever digital stuff you want to
decode… so long as whatever comes out of it can go into Gnuradio. =)
BTW that offer obviously goes for anyone else who wants example data to
play with.

I’m jumping in a couple days late here, but a resource that seems to be
disappearing is KD7LMO’s over the air captures. His old website[1] is
down, and the ANSR mirror[2] has disappeared as well. You can see a
listing of what was available on archive.org[3], but I can’t pull down
the actual captures right now. Maybe somebody else has grabbed the
collection at some point and can drop it off somewhere to be re-hosted?

Ben,

I’m a bit late, but may be this will be helpful:
http://signals.radioscanner.ru/base/
Site is in Russian, but signal names are in English and you could also
use Google Translate:

Hope this helps.
