GnuRadio 3.7.2.1
OSX 10.8.5
I was setting up a flowgraph in GRC using the
mpsk_receiver_cc block and encountered a problem.
Don’t know if it is a bug in the GRC xml or a
missing method in the block code.
In GRC, the mpsk_receiver’s “loop_bandwidth” parameter
is underlined in the properties popup, indicating
that it can be changed during runtime. I entered the
name of a variable that was created in a Wx Slider widget.
At runtime, when I try to change the value, I get:

AttributeError: ‘mpsk_receiver_cc_sptr’ object has no attribute
‘set_loop_bandwidth’
I checked the code, and indeed, there is no method by any name
for setting the loop_bandwidth attribute.
