I just cracked open a Ramsey PR-2. The secret sauce is a upc1678,
available at mouser for $2.50.

Hi all
Newbie here. I am using FLEX 2400 daughterboard with USRP. On
the exploring GNUradio web page it is mentioned under the title "what goes
in FPGA" that there is a NCO and Decimation filter in FPGA. I did a quick
scan of the FLEX 2400 receive schematic and it appears to me that it

Thanks, Matt. So i

As mentioned earlier, I'm working on a front-end board for the Basic-RX
to provide some gain and selectivity for HF use.
Question -- has anyone figured out what sort of gain is optimum ahead of
the the Basic-RX for use as an HF receiver? I can easily tweak the
front-end design to provide anything
Thanks for the report.

Following the trac instructions my Cygwin installation was going smoothly
until
hitting wxPython. I installed the latest version 2.8.0.1.
Some observations:
1) the statbmp patch appears to already be applied

Hey,
1) I want to add a switch for which USRP (the which_board argument) is
used in the example scripts. -w seems to be used by some scripts
(usrp_siggen.py for example); is -W open?
2) What's the proper procedure for submitting patches? I've seen people
email to the list...
Thanks,
Dan

I tried it uder Ubuntu and openSuse and it runs fine.
(openSuse required python-gtk and pyxml packages)
Up to now, I have tested several visual components, and I had only problem with
USRP source.
Below is detailed output.
I think it will be very useful tool and look forward as you continue this

I have been working on a graphical interface for gnu radio. I was
wondering if there are any gnu radio enthusiasts willing to check out my
program and give me some feed back. I call it gnu radio companion or
GRC. Here is the link http://www.joshknows.com/?key=grc
Thanks,
