The grc dialtone flowgraph py would work ONLY if i changed BOTH
self.audio_sink_0 = audio.sink(44100, "hw:0,0", True)
to
self.audio_sink_0 = audio.sink(32000, "plughw:0,0", True)
and
self.samp_rate = samp_rate = 44100
to
self.samp_rate = samp_rate = 32000
not sure what to make of that...

can some one tell me what exactly does the gr-qtgui module add to gnuradio ?
im having troubles getting it to compile, and if i don't really need
it then why bother?
the gui should still work without the qt libs correct?

somethin i have in my head i want to throw out there...
how hard would it be ( or is it even possible? ) to create a device that
appears to gnuradio to be a functioning USRP but actually passes data to and
from capture files. This would be nice when working on programs but away
from hardware, and
I would like to get my usrp conneced to my TVRO satellite dish. I am
wondering...
Is the DBSRX daughter card suitable for direct connection to a satellite LNB?
I am thinking it will be easier to let the sat receiver do the lnb
power and polarization control
Is it be safe to connect to the lnb loop-
most sat boxes have a IF output for secondary receiver, i will use the
reciever to power the motor / lnb / polariztion control. just wanted
to make sure any crap coming down the line wont blow up the dbsrx but
it sounds safe
thanks
