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

[Ben Reynwar]

That sounds like the example is out-of-date.  It's calling some
function that expects a different number of arguments than it is
giving it.  If you included the entire error output then we could
better see what the problem was (i.e. which function is raising this
error).

Cheers,
Ben
