I am new with sparksdr and I customized sparksdr to run with radioberry. Now I have one problem, to know if ( or how ) sparksdr controls the the power output and reach the 5 watts from the module PA5W_V2. I tried rf gain without success.
In pihpdr I can control the PA5W_V2 power output.

Thank you.

Below the VFO there is a drive slider.  Make sure to move that up:

Mine is 161 currently.

On HL2 we need to enable the PA under the three ... menu, but I don't know if this board needs that.
There is also a setting for "Tune Drive" that is set separate from the VFO drive.  The note uses the tune drive level.

Hi Josh.
Thank you for your help.
The drive does not work for my config, ( Radioberry + PA5W_V2 ), I think can be a compatibility problem related to my radioberry that is a chinese hardware. It is working nice with pihpsdr, but sparksdr is a wonderfull product and I m interested in using it.
