After successfully installed uhd and gnuradio from the next branch on
F13 i run a simple gnuradio-companion test with a flex 1800 as the
source and an FFT sink.
It seems that when i use a uhd source my signal is ~ 80dB lower than
when using a USRP source. What is the explanation of this?
Also, it used to be that I needed to be in the “usrp” group in order to
access the USRP.
Now i deleted this group and i still have access to usrp (even when the
source is not a uhd one but a usrp source)!
My understanding is that if i use the uhd device then i can do that
(ie, don’t need to be in the “usrp” group) but it seems to be happening
even with the usrp source.
What am I missing?
