[Discuss-gnuradio] Difference in gain using gnuradio 3.1.3 and the trunk (at least on RFX1800)

[Per Zetterberg]

Dear All,

I have connected a signal generator to my USRP and I am using a CW. Thus I
have a constant input power. I am running the usrp_rx_cfile.py utility
(exact command line below). If I run gnuradio 3.1.3 then the amplitude I see
is 16dB higher than if compile from the trunk (checked  out a week ago or
so). I think it has to do with the new daughterboard  code being different
from the old python one. I am using an RFX1800 daughterboard.

The signals are also conjugated with respect to each other
