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? Thanks Achilleas
