[Discuss-gnuradio] tvrx_wfm_rcv.py

[Robert W McGwier]

On my machine, running the latest and greatest (just did an update to 
make sure),
attempting to run

tvrx_wfm_rcv.py  with this:

src = usrp.source_c (0, decim, 1, 0xf0f0f0f0, 0)

as line 34 results in:

if I replace that line with

src = usrp.source_c (0, decim, 1, 0, 0)


it runs and appears to be doing the right thing.  There is no which or 
whichside or
which_side parameter to be parsed.  It is most decidely NOT reading the 
USRP to
find out which, if any, tvrx boards are on.  I removed the one on RX B 
and left
the one on RX A.
