Method 2:
Use the Betaflight GUI command.
We could also use the Betaflight CLI commands to change the frequency
and power of the VTX.
For example, set the frequency to 5865 and power to 200mW ( 1 for 25mW /
2 for 200mW);
set vtx_band=1
set vtx_channel=1
set vtx_freq=5865
set vtx_power = 2

How to Use the PitMode
PitMode allows racers to power up their video transmitters during race events without
interfering with other racers and still having the ability to change VTX settings or do some
testing. Range is limited to 2-3m and transmission happens on the selected frequency.
The PitMode is active when only red LED flash solid.
How to active the PitMode:
Enter the OSD menu by radio transmitter sticks.
FEATURES -> VTX SA -> CONFIG -> PIT FMODE. Then select the PIR status.
How to exit the PitMode:
As the same above, select the OP MODEL to FREE
to close the PitMode. Then the VTX will recover to the 25mW power status.
