Dear Matt,
Can I connect multiple USRPs to one GPSDO kit ?

I have downloaded (git clone http://gnuradio.org/git/gnuradio.git), built and
installed (according to wiki instructions) the latest version of GNU RADIO.
I am working on Ubuntu 10.10 platform.
I have the following exports added to bash.bashrc:

I am having the same problem. When the configure breaks on UHD it says I
need libuhd.1.x.x. I have libuhd.0.0.2 in /usr/local/lib and uhd.pc is
in pkgconfig directory. I have PKG_CONFIG_PATH=/usr/local/lib/pkgconfig.
I have also done sudo ldconfig. I really dont want to wipe my whole
system.
Hi, All,
I'm using USRP1 with XCVR2450 daughterboard.
I transmit packets with OFDM modulation as in benchmark_ofdm_tx.py.
Using usrp_fft.py I detect the wave form as

Hello,
The TVRX2 sounds very interesting. How are the two receivers mapped to the
output? Does each receiver map to a different frequency range on the output?
The two receivers would be great for decoding and following trunked radio
systems with a dedicated control channel.

2) TVRX2 Daughterboard
The TVRX2 daughterboard replaces the original TVRX. It is a dual
receiver covering 50 MHz to 860 MHz. There are 2 entirely separate
receivers which can be used simultaneously, either on the same or
different frequencies, each with a bandwidth of up to 9 MHz (thus

If you are using 2 USRPs then the simplest way to do this is to put the
GPSDO in one unit and connect it to a second with a MIMO cable.
If you need to connect
I'd like to record raw broadcast (rx_cfile) with either a USRP1 or USRP2
(have both) but with all samples known to as accurate as the system
clock, preferably millisecond to sub-millisecond accuracy. I considered
writing a block that outputs the number of milliseconds since midnight
as shorts that

Dear all,
What's the lowest power of the signal that LFRX can capture? How can I
receive a signal between -20dBm and -10dBm by LFRX?
I already set the USRP gain to the greatest, 20dB, but still cannot really
capture any signal.

Yes

Hi,
Look at the schematic of LFRX and change the resistors in the feedback to get
20dB of gain more. Your bandwidth will be limited to about 15MHz but LFRX will
be still usable in the full bandwidth, or you can set lower gain to get more
bandwidth if needed.
With my LFRX set to 20dB of gain I
