I found a bug in digital_bert_rx.py. My current version of GNU Radio is 3.6.2. The bug is in line 118(I'm not sure if I have changed the file already), self._source = uhd_receiver(options.args, options.bitrate, Here, the "options.bitrate" should be replaced by "symbol_rate". May be you guys have fixed this bug in 3.6.3? But still problems in digital_bert_rx.py or digital_bert_rx.tx.py, cause I do the bpsk test and everything works well. But the other mods/demods cannot get a correct BER even though I fix the bug above. The BER is always aroud 0.1666 or 0.20! Can anyone help me on this? Thanks, Charles
