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

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.
