Well, actually, it is a piece of wire. Its one of my multimeter probes (the 
black one as opposed to the red one) connected to a banana-BNC adapter and 
the banana-BNC adapter is connected to a BNC-SMA adapter connected to the 
RX-A input of the USRP.

I normally get a significantly strong signal from KBIG here, as it is the 
strongest signal in the entire band from 30Mhz to 500Mhz. Its EIRP is 105,000 
watts, line of sight about 35 miles to Mt. Wilson. My office is on the second 
floor and I get great reception from Mt. Wilson.

I can see many other stations from Mt. Wilson here with my spectrum analyzer 
including my ham repeater on 448.9Mhz whose output is just 50watts, also with 
a piece of wire, but it has a -120dBm sensitivity and thats another story 
altogether.

OK, just thought there might be a speed thing going on. I can observe that the 
audio gets a little better if the stdgui window is really small as opposed to 
really large. I tried commenting out the vbox.Add's but it just makes it the 
same as the small stdgui window.

An interesting problem to study.
