Hi,
I have used the gr-atsc receiver and the TVRX to prove to track and
decode DTV/HDTV signals. I am trying to do the same thing with the
RFX400 board, although I am running into trouble. There is an
available signal at 491 MHz, which works fine when I record data with
the TVRX, but the

Hi,
I am trying to record I/Q data from two daughterboards (currently a
TVRX and a RFX400) on one USRP simultaneously. I have no trouble
recording data from either of these daughterboards independently, but
when I try to record data simultaneously, I receive the following error:

To anyone using the following:
I'm using the USRP with a Microtune UHF band tuner.
What I see is that there is a significant artifact at 512 MHz, and a few
more, but
another 'clear' artifact at 640 Mhz.
I believe these to be induced by the digitzing clock of 64 MHz.
However, since I avoid 'h
Between "gr_simple_squelch_cc" and "gr_pwr_squelch_cc"? Besides that
the latter inherits from a base class, and is generally a little more
robust (e.g. allowing for ramping on and off), I don't see any
significant differences between them. Thus I'm wondering if both are
used by folks, and

Hello everyone,
I am planning to implement a small software-defined radio with a bandwidth
of say 50-300 MHz at first. The system should be able to receive AM, FM, PM
signals over the mentioned RF spectrum with upto 10MHZ baseband information.
This would require an IF of at least around 11-12MHz.

Hi David,
You can get the project from
http://www.sdr-cn.com/wiki/wiki.asp?db=WikiAsp&o=GnuradioVc6project ,The
project only include the gnuradio framework codes,I think it isn't fit for "a
pure c++ interface to the USRP",maybe more work need to do. I believe it is
more useful for newbie to
It is working, thank you very much. Now i have to find out how i can
record 27.195Mhz to file and re-send it afterwards.
Is there a sample that does that allready?
Greetings

Any idea what is happening here? I'm wondering if my signal is so weak,
that the 8-bit option is truncating all the data off. When running
usrp_wfm_rcv.py I can only get one strong FM radio station.
Are you using a decent antenna? I used a stretched paper clip[0], which
