I have a following doubt here: there are two cables, one that brings 10.7
MHz if signal from external rf frontend to the usrp, and utp cable that
provides power and control signals for rf frontend. My first doubt was that
WBX LO signal is directly induced in the lines on LFRX board, but as soon

Hi all,
As I described in one of my previousposts, I wanted to have several
receiving paths for 434 MHz, and my USRP is equipped owith WBX and LFTX. So
WBX is one, and for the other, I designed small RF frontend using TI's
CC1000 that donwnconverts the signal to 10.7 MHz which can be used with
LFR
