psk31.grc is BPSK and 6_psk.grc is QPSK. You should put both the transit and receive in the same file without the osmocom source and sink - connect the transmit and receive with a link - cut out the hardware. Then debug the encoding and decoding. Otherwise, it may be hard to figure out if the problem is encoding/decoding or timing, frequency or phase issues with the hardware. > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
