[Discuss-gnuradio] Need help with LFRX
Hi all ! I am interested in observing spectrum around 200kHz and tried the following command : ./usrp_fft.py -R A:0 -f 20 -d 112 with a coil antenna connected to RX-A input of LFRX daughterboard. Should it work ? If so, does it mean that there is something wrong with my antenna ?

Re: Re: [Discuss-gnuradio] How to display mux value?
Hi Steven, It works fine ! Together with Charles Swiger's suggestions, you helped me with three possible approaches : = m = usrp.determine_rx_mux_value(self.u, options.rx_subdev_spec) print "mux1 = %x" %(0x1 + m) print "mux2 = ",hex(0x1 + m) print "mux3 = 0x%08x" % (0xL & long(m)) = Thanks for both of you, Pawel On Tuesday 08 May 2007 16:47, you wrote: > (Sorry for sending this twice, Pawel, I forgot to send to list.

[Discuss-gnuradio] How to display mux value?
Hi all ! Who knows how to display mux value ? print "mux =", hex(usrp.determine_rx_mux_value(self.u,options.rx_subdev_spec)) displays negative values, for example -0xf0f0f0e How to interpret negative value ? and how to interpret 7 digit hex number istead of 8 digit. regards, Pawel ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] LFRX installation questions
Hi all ! I have several questions regarding LFRX daughterboard : Why does LFRX have two inputs (RX-A and RX-B) and not one like DBSRX for example ? Do I need a separate RF front end to use it ? Is it necessary to reburn eeprom after installation of this daughterboard ?

Re: [Discuss-gnuradio] Problem with DBSRX rev 2.1: "No class defined to handle daughterboard (dbid = 13)"
It works ok now, thanks Matt. I burned eeprom because earlier I got a message "Invalid EEPROM contents" It seems now that it wasn't necessary. Pawel ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Problem with DBSRX rev 2.1: "No class defined to handle daughterboard (dbid = 13)"
I have DBSRX rev 2.1, after burning eeprom with the command ./burn-db-eeprom -t dbsrx2 -A -f an error appears when I try to use the daughterboard "ValueError: No class defined to handle daughterboard (dbid = 13)" Similar problem was addressed in http://www.nabble.com/Problem-with-RFX1800:-"No-class-defined-to-handle-daughterboard"-t2068897.html but in my case rebuilding with the latest version didn't solve the problem.
