Hi Tom,
Thanks for the reply. I have a few more question on this regard and also
some additional questions on benchmark_rx and tx.
1. There is a 'thres' parameter in the receive_path.py code, associated
with the benchmark_rx.py code. The default value is 30. It says, thres =
30, # in dB, will hav

Are you selecting the correct antenna? Its possible the default RX

We'll check it out, but we only have the one antenna hooked up...
It'd be interesting to find out that the SMA connector can pick up the
signal! So I gather there should /not/ be any change in receiv
Hi Josh,
I have no d8psk*, dbpsk*, modulation_utils2*.
Which branch do you use for this?

Hi,
We're using USRP2s with the RFX2400 daughterboards, and we've recently
switched from the old USRP drivers to the UHD drivers as per general
recommendation. However, we've run into a few problems that have us
stumped:

Just found the digital_swig.py is located
at /usr/local/lib/python2.7/dist-packages/gnuradio/digital
So I change "import digital_swig" to "from gnuradio.digital import
digital_swig" and the complaining disappeared. Seems for these python
modules, i still need to give a full path, even I have impor

I had never heard of fastGPS; sounds pretty useful. What is the end goal
for your receiver?

Hi list,
the SpecEst toolbox has more fun and exciting stuff:
- First thing is a GUI. It connects to a file or UHD and can show live
spectral estimates of the incoming signal using any of the existing
estimators. For simple debugging purpose, this is not as useful as
uhd_fft.py, but it's a g

Dear everyone:
You see in usrp_basic.h there is a function named _write_9862() and it
uses function usrp_9862_write(),defined in usrp_prims_common.h. And
usrp_9862_write() uses function usrp_spi_write(), also defined in
usrp_prims_common.h.
usrp_spi_write() uses function write_cmd(), defin
