Hi Jim, I'm pretty sure all the bits and pieces are there, but I don't think anyone else has connected them together yet. It would be great if you did. Given the low data rate, you could probably handle the HDLC packet parsing and bit-stuffing/destuffing in python. Or you could write a new block to handle it in C++. For a starting point, please take a look at the GMSK examples. They're similar to what you want to do, only the bitrate is 500 times faster ;) See especially: gnuradio-examples/python/gmsk2/benchmark_gmsk_tx.py, benchmark_gmsk_rx.py gnuradio-core/src/python/gnuradio/blksimpl/gmsk2.py, gmsk2_pkt.py Eric K7GNU _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
