It came from a VERY old traditional GR build.
I thought *no changes there in source code init stage was altered* after moving 
on to uhd, I was wrong.

Time for me to upgrade from trad to uhd. Latest git trad compile does serve my 
needs still 100%

Thanks,
Patrik

    Hi All,

    I can not see in source code where GR is setting the TVRXx gain. I'm 
referring to
    gnuradio-core/src/lib/io/microtune.cc

    If so (not set), what does it default to, max? See page 12 and forward. The 
tuner document can be found at 
    http://www.poes-weather.com/~patrik/usrp/4937-DI5-3x8899-2.pdf

I don't know where that file came from--it's not in the current Gnu Radio 
source tree.

  But certainly, in UHD, in the "db_tvrx.cpp" file the constructor for the 
"tvrx" class initializes the gains on the device.
