Re: [Discuss-gnuradio] Gnuradio ASK/OOK Binary sequence

[Chris Kuethe]

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:

GDB has a 'break' feature; why doesn't it have 'fix' too?
