Hello to everybody.
First of all, I am working with Ubuntu 10.10 and GNU Radio 3.4.0. I
tried to
run the usrp2_wfm_rcv.py graph but I got the following error:
Traceback (most recent call last):

ZeroDivisionError: float division
I read in the mailing list that this problem could be related to the
setting
up of the gain slider control but I don’t know how to fix it. Could
anybody
help me?
A lot of thanks!
Regards.
Eduardo.
