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 ?
Regards,

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,

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 ?
Reagrds,
Pawel
I tried it uder Ubuntu and openSuse and it runs fine.
(openSuse required python-gtk and pyxml packages)
Up to now, I have tested several visual components, and I had only problem with
USRP source.
Below is detailed output.
I think it will be very useful tool and look forward as you continue this
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.

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)"
