Dear all, After updating my FC3 and reinstalling the latest tarballs I think I have a distribution with a working USRP module (with Basic Rx,Tx and 4937 daughterboards). Thanks for the comments/suggestions.
However there are still some issues that I have not resolved: benchmark_usb.py works fine and gives me a max of 32MBps rate. It also gives a warning: usrp_standard_rx::set_decim_rate: WARNING rates > 128 result in incorrect gain. How should I interpret this? Also, some of the examples in usrp import the module as "from gnuradio import usrp" but in the code they use "usrp_tx = usrp1.sink_s (0, tx_interp)" The way I fixed this is to import usrp1 explicitely "from gnuradio import usrp1" Is this the right way to fix this problem? I would expect that "from gnuradio import usrp" also import all versions of usrp, ie, 0 and 1 Any thoughts on this one? Also, wfm_rcv.py and wfm_rcv_gui.py seem to be different in the way they access the RF front end: the former does it explicitely (and gives me errors) while the latter has this part commented out. I do not get any errors when I run the wfm_rcv_gui.py script, but I do not receive any FM stations either (my 4937 daughterboard is sitting on board B). This is the output I get when running ./wfm_rcv_gui.py 97.1 RX d'board A: Basic Rx RX d'board B: TV Rx usrp_standard_rx::set_decim_rate: WARNING rates > 128 result in incorrect gain. All windows open with data, but I only hear noise...same for any other frequency I tested. I wonder if the file included in the tarballs is obsolete...
