Hi Josh, on the SMA connectors I had connected my transmit receive antennas. I
wanted to know if while transmitting and receiving signals using USRP sink and
source blocks, can I silmatenously probe any pin on the transmit/receive
daughter board inorder to see the signal out and in to USRP.
Should we try and put this on CGRAN?
I tried to contact the developer regarding some issues (specifically, that
gps-usrp doesn't compile with the latest gnuradio trunk), but got no
response.

Dear All,
I am trying to issue 5 calls to tx_16sc (of 371 samples each i.e.,
one ETH packet per call) to the USRP2. I transmit a simple sinuswave. If
I set send_now=1 in the metadata it works as expected and I can see
the signal on a spectrum analyzer. If I set send_now=0 I can only

...Okey now I have another problem. I downloaded rev 10851 of the gnuradio
from the trunk and now I get two errors when I try to make.
I configured ld.so.conf as describe in your wiki. But I still have make

Jonathan,
It works ok for me, except for the mpsk_receiver with the setup from
http://www.nabble.com/QPSK-phase-noise-td22934944.html.
This is the constellation I get for a 40 dB SNR BPSK:

You want to probe the SMA connectors. The pins tx0-tx7 are digital
control lines. If you see any signal on the control lines, it is
probably very weak leakage from the DAC.

Since I have tested the tx code (bbn_80211b_tx_port2.py), I wanted to run the

I've been looking over the GNU Radio code and I can't seem to figure what is
being done in /usrp2/host/lib/open_usrp2_socket.cc file. Specifically,
lines 97 through to 128.
What I think is happening is that a pair of connected sockets is created
(97) then a process is forked (102). So, the

A bug was found that effects the XCVR2450 in transceiver applications,
especially tunnel.py. A fix has been applied to the host code in r10853
of the trunk. This fix is for XCVR2450 + USRP (does not apply to the USRP2).

Hi everyone,
The CGRAN upgrades are finally complete. After our server took a hit last
week, I figured it was time to upgrade some things while I fixed some
others. CGRAN is now using Trac 0.11.4 and subversion 1.6.0, with some
python and apache module updates in the background. This seems to
