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: http://www.inguardians.com/pubs/GRC_signal_analysis_InGuardians_v1.pdf https://nccgroup.github.io/RFTM/ https://cansecwest.com/slides/2015/From_Baseband_to_bitstream_Andy_Davis.pdfOn Sun, Sep 20, 2015 at 1:13 PM, 0x00-0xff <address@hidden> wrote: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 (keyfobson 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 matchthe sequence I see in baudline or wx_scopeWhat I realy (realy) want is, to save multiple received ASK/OOK signals intoa file with corresponding frequency. But any help is appreciated ;) Kind regards, 0x00_0xFF _______________________________________________ Discuss-gnuradio mailing list address@hidden https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
