Chris,
Marcus had mentioned about experimenting with ICRON Ranger 2101 USB 2.0
Extender for about 150foot. Check out these threads...

From the FAQ, ALL daughterboards work on both the USRP1 and USRP2.
3. Does gnuradio-3.1.3 work with USRP2?
No, you'll need to use the newest SVN code.

Does the USRP2 use ethernet to transmit data? I just saw a picture of it.

Hi,
I'm putting my USRP and antenna on a 56 foot mast. For my application
the USRP must be near the antenna. I'd rather not deal with the
logistics of placing the computer on the mast as well. Any ideas on how
I can get the USB data from the top of the mast to the ground where my
computer is?

Hi Dimitris, I scanned over your code and think you just need to add
"self" to one statement. We add self only if there is an external
port. Your rds_rx block has an input but is a sink and therefore no
output. Therefore at line 102 rds_rx.py you may want to add something
like:

Hi,
I would like to know if it is possible with GNU Radio to have callbacks
from a processing block into python to trigger a reconfiguration. A
possible scenario is a radio which changes its receiver frequency when a
the signal was lost (due to a change in the transmitter frequency). For

Hi
I'm very new to GNU radio and just recently managed to get a successful
compilation working. Simple built in-examples (such as benchmark_tx/rx) are
working fine.
However, I was wondering it was possible to transmit more complex data via
USRP, such as a JPEG file. Any guidance/source code/rele

Are you aware that the isolation between the transmit and receive channels
of USRP daughterboards is generally < 40 dB? (This fact made it impossible
for me to use the Transmit channels in my application.) It is quite
challenging to have transmit and receive channels operating simultaneously,

Hey,
I have two XCVR2450 Trancievers.I have also two wire antennas connected to
each.
So,I have separate transmit and recieve paths, but I am using a single USRP.
I am using the transmiter and reciever daughterboards at almost the same
frequency.
I am transmitting at 2.45GHz and I expect to reci
