Another trick to get higher frequencies is to use an image that is
produced the DAC. If you program the DAC to 29.3 MHz, you'll also get RF
at the SampleRate +/- DAC Freq. So you'll get a signal at 128 - 29.3 and
128 + 29.3. So in this case 98.7 and 157.3. The signal levels will be
lower, bu
You simply can't do that. The hardware on the USRP has a DAC capable of
128MS/s (iirc), which means that AT MOST you could get it to put out a
64 MHz signal. If you shift over by 98.7MHz, then that'll be past the
DAC's ability to reproduce an accurate signal (it will in fact fold over
to like 98.7
Hi gnuradio's
I'm trying to FM TX, can I do this with the fm_tx4.py:
[EMAIL PROTECTED]:/home/gr-build/gnuradio-examples/python/usrp # ./fm_tx4.py -c 98.7
When I run it I get this:
[EMAIL PROTECTED]:/home/gr-build/gnuradio-examples/python/usrp # ./fm_tx4.py -c 98.7 ddc_freq = 98.7

Hi all,
I'm trying to re-use the USRP code (where I can) for my own SDR device
which also uses the FX2 chip. I've managed to install the GnuRadio onto
my Debian system and have built the USRP source code.
When I run the usrp-0.8/host/apps/test_usrp_standard_rx executable I get
an 'usrp[0] de
