[Discuss-gnuradio] usrp_nbfm_ptt.py Error: __init__() takes exactly 4 arguments (6 given)

[mario behn]

Hi,

I'm trying to make usrp_nbfm_ptt.py to work with a N210 Rev.4. on
Ubuntu 11.10 and with Gnuradio
3.5.2.1

After my normal system info (see below), however, I get following message:

The debugged program raised the exception unhandled TypeError
"__init__() takes exactly 4 arguments (6 given)"
File: /home/usrp1/USRP/gnuradio/gr-uhd/examples/usrp_nbfm_ptt.py, Line: 81

I wonder if anyone has seen this error and let me know what I'm doing wrong.

With kind regards

Mario Behn
