Thanks, I've already red those pdf's.
The adsb grc doesn't help me enough :)
I'm getting large binary files with 0's and 1's which doesn't resemble
the binary sequence I'm looking for...

Check out gr-adsb
(https://github.com/wnagele/gr-adsb/tree/master/examples) - the
example flowgraph uses a threshold block to produce 0's and 1's. From
there you can unpack bits to bytes, add a constant of 48 (numerical
value of ascii '0') and come out with a character stream of '0' and
'1', which you can then feed into a file sink (opening /dev/stdout)
Also check out these tutorials:

Hi guys,
After trying several tutorials en demo's... I need your help.
I'm trying to get the binary stream from a ASK/OOK modulated signal
(keyfobs
on 433mhz).
I've been able to manually write down the sequence and retransmit it:
https://github.com/0x00-0xFF/gr-x10
How do I get the 0's and 1's on /dev/stdout (or file).
The tutorials I've seen, give me a load of 0's and 1's that do not
match
the sequence I see in baudline or wx_scope
What I realy (realy) want is, to save multiple received ASK/OOK
signals into
a file with corresponding frequency.
But any help is appreciated ;)
Kind regards,
0x00_0xFF
