Hi, Strom,
Thanks for your work.
I just tried to show RF spectrum using usrp_spectrumsensor.py with ettus usrp1.
The apt cmd shows uhd_003.010.003.000-2 device lib/host installed. No where to apt-get or download udh_3.10.3.0-0 to replace the installed uhd_3.10.3.0-2.
Could anyone please give some advice on how to solve the error?
Once there was a gnuradio livesdr iso pkg file from corganlabs, but I can't find it from internet now. Anyone knows where to download this livesdr pkg?
Thanks.
zeng,xw
