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)
