I've discovered that after I turn on the USRP and start receiving there is some noise which because of some strange reason disappear when I start the transmitting part of the board. For frequencies around 150MHz with the WBX-board
and USRP1, the noise floor is reduced by 5dB, and seriously improves reception. To make sure that I receive well, I made myself a simple script like this: #!/usr/bin/ from gnuradio import usrp u= usrp.sink_c
