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
