[Discuss-gnuradio] Error executing usrp2_wfm_rcv.py

[Eduardo Lloret Fuentes]

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):
   File "./usrp2_wfm_rcv.py", line 289, in <module>
     app = stdgui2.stdapp (wfm_rx_block, "USRP2 WFM RX")

 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.
