We're new to gnuradio and have a shiny USRP2 with a DBSRX
daughterboard. More details are below.
The system is kind of working, but usrp2_fft.py reports Failed
(or Invalid if there's a typo) for every frequency we enter regardless
of whether it's in the supported range or not. Oddly, the entered value
does affect the spectrum display and the signal we're supplying does
show up sometimes, but the relationship between the frequency we enter
and our generated signal is unclear to us.
srp2_probe returns sensible information:
Converter Rate: 100000000 Hz
Gain Range: 0.0 - 84.0 step 1.0
Freq Range: 500000000 Hz - 2600000000 Hz
I've looked at the source and don't see an obvious way to get
more information on the failure. Is there one?
Are there other diagnostic tools we should try?
We're using raw ethernet (and running everything with sudo).
Should we use UDP or UHD instead?
Any tips would be much appreciated.

Configuration details:
Ubuntu 10.04
We originally installed the prebuilt 3.2.2 package available via
the Synaptic Package Manager, but uninstalled it.

Did you do the conversion steps necessary to get a DBS_RX to work with
the USRP2?
