Just to clarify,
I am not talking about setting the gain in software, spectrum plot gain
for example.
I’m talking about the hardware gain setting controlled via I2C

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
I’m don’t think that code is related to TVRX. For old non-uhd driver
you need to look in the usrp/host/lib/ directory.
If so (not set), what does it default to, max? See page 12 and
forward. The tuner document can be found at
Loading...
In db_tv_rx.cc constructor, line 101, the gain is initialized to
middle.
The gain ranges are also available via the API and you can see many of
the examples also initialize the gain to middle value.
