Does anybody have a copy of the source code for the newest version of USRP
(not GR-USRP) or know of a place to get it besides Sourceforge CVS? The SF
CVS repository has been down the entire week and I am not hopeful that it
will be up anytime soon. Thanks for any help!

It just seeemd strange to me that a very large number, d_freq, which is

The function has the right name, mod_2pi, but the wrong implementation ;)
These are commonly called bugs ;) Hence my comments above about doing the
mod the right way.
Roger that. Plowing right ahead with a hacked 1st order PLL filter,

Ah ha - it's invert either I or Q.

phase1 = gr.multiply_const_ff(-1)

I have to make an antenna array to discover the direction of arrival of one
signal. For this, I need to connect four antennas to the USRP board, and
export the data to an algorithm that will detect the direction of arrival.
Does anyone have an example that uses the four ADCs of USRP board?

G'day,
I'm trying to create a gr-audio-portaudio package for pkgsrc. Running
gr-audio-portaudio's configure script will lead to the following error
message:
echo $ECHO_N checking for portaudio = 19... $ECHO_C 6

Thanks to tons of grunt work by Eric, we have used the highly tuned
ring buffers in the audio_portaudio_sink code and it functions nicely
with a little bit of operator help.I can now get solid performance
on all Linux hosts with the example code
mono_tone_portaudio.py and
