Hey, guys I am studying the examples these days. I met a question when I read am_rcv.py. Why do we need a offset frequency of 30kHz in this case? src.set_rx_freq (0, IF_freq) actual_IF_freq =src.rx_freq(0) actual_offset = actual_IF_freq + station The three lines are conf

GLONASS spec's are available on-line from Russia. Google found the site, and the spec is a decently sized Word document. The GPS L1 Freq is a CDMA signal at 1575.42 MHz, with a signal BW of~3 MHz. GLONASS is FDMA, with 25 500 kHz channels from 1589 to 1610 MHz. I suspect that you could design a

I've posted a number of OTA (Over The Air) samples on my web page. These include 7.2 and 10.0 MHz captures in the HF band. (As requested by someone on this board). Also included is 2 second snap shot of GPS L1 carrier. Should be good for some software work. Captures: http://www.kd7lmo.net

Hey all,   I was looking at the build codes(.h, .cc., .c, .i, .py) for the USRP and the Gnuradio Docs seperately and I am not sure where exactly these two meet. I was guessing that the fusb would be calling both the headers from usrp and gnuradio, but doesn't seem like it. Can anyone please point m

Thanks for the information. I did install the RPMs as well as version libstdc++-3.3.3-7 from FC2. The wxPython*rpm were expecting version libstdc++.so.5 of the C++ libraries. However, I have the same core dump issues. Using the nbfm_rcv.py from the latest CVS gnuradio-examples it runs correc
