[Discuss-gnuradio] gain control extreme non-linearity--is my hardware broken?

[Marcus Leech]

I've noticed while playing with the gain control with the DBS_RX and 
USRP that the range
 of 50-79 makes no difference to the signal level, and then when I 
switch from 79 to 80, there's
 a sudden 10dB jump in signal level.  Also down between 40 and 50, the 
gain control only seems
 to produce a 5dB difference in signal level.

This is with the latest tarballs, including usrp-0.10.

Should I worry?
