Adjusting PitMode Power Level on VTX

Hello everyone,

I’m currently working on a build running ArduCopter V4.6.0, using a Foxeer F405 Plug V2 flight controller and a Foxeer Extreme VTX connected via IRC Tramp.

I would like to know if it’s possible to adjust the minimum transmission power in PitMode, for example to 25 mW instead of the default 0 or 1 mW.

Because when my drone switches to PitMode, I completely lose video signal unless I’m within about 10 cm of the VTX antenna.

If there’s an option in Mission Planner or a setting I might have missed, I’d really appreciate your help.

Thanks in advance!
