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 c

No, there are 2 separate streams, both at complex baseband.

Pass them in with the device arguments, just like addr, serial and the
rest. Its just more optional key/value string pairs
device_address["recv_frame_size"] = "1024"

Could anybody please tell me how to set the following parameters? I am
working on supporting UHD in the Python digital communication example
and hopefully I can soon share my code with the list.

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

Cat your /usr/local/lib/pkgconfig/uhd.pc files and
gnuradio/config/grc_gr_uhd.m4 and make sure the version reqs match up.

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.

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.

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

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. Oh,
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:

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