Switching Power Levels via RC
Parameter [VTX_POWER] is assigned to RC9 ([RC_OPTIONS])and connected to the Green [SD] switch on the TX16S
Start with all switches selected "away" from you
In this "away" or first position, the Green SD switch will show 0mW or 25mw on the OSD. This corresponds to the VTX outputting 25mW
In this "middle" or second position, the Green SD switch will show 200mw on the OSD. This corresponds to the VTX outputting 250mW (Ardupilot -> AKK VTX software mismatch)
In the "down" or high position, the Green SD switch will show 800mw on the OSD. This corresponds to the VTX outputting 1W as confirmed by observing the VTX Red LEDS
Manual VTX power selection
Hold the vehicle pointing away from and pitched down at a 45 degree angle
Look through the square hole at the rear of the frame and you will see the three VTX indicator lights
Green LED is the 12 "Bands"
Blue LED is the 8 "Channels" within that band
Group of 3 RED LED is the power indicator
Follow that;
O = Red LED on
X = Red LED off
OXX = 25mw
XOX = 250mw
XX0 = 500mw
OOX = 1000mw
OOO = 2000mw
OXO = 3000mw
On the VTX on the left side in this view orientation (near the RC RX) is 2 buttons
Use the button closest to the Nose to switch between power/channel and band.
One single short press to cycle through the 3 parameters.
Use the button closest to the rear antenna to a change setting within the selected parameter. Use the above VTX power LED table to select the desired power output.
In the US the FCC requires that the operator is a licensed "HAM" radio operator to transmit a radio frequency of greater than 1W.
