Hi all,

I've just pushed changes to the 'fairwaves/umtrx' branch which allow
UHD to actually control UmTRX tuning. This means that now we don't
need to calculate Rx/Tx frequencies by hands to run OpenBTS - it will
tune automatically. I've updated the wiki to reflect those changes as

 Changes are based on the Sergey Kostanbaev's work to move all our
LMS6002 control from umtrx_lms.py script to the UHD. The next most
important things to get working there are:
 * gains control aka VGA1/VGA2 in LMS
 * antenna control aka PA/LNA selection in LMS
 * bandwidth filtering control aka LPF filters in LMS
 * automatic calibration utilities
