TX Power

Change transmit power in the active link’s settings. Hardware capabilities and units depend on the adapter and driver. Recheck displayed power and link health after changing antenna, band, or radio.

NOTE: When adjusting the TX (transmit) power settings, it is your responsibility to adhere to the rules and regulations of your country.

Set the power for the active radio​

  1. In QOpenHD, open the active Link settings and find the transmit power controls for Air or Ground.
  2. Select the adapter if the build lists more than one. The device may expose transmit power in milliwatts or as a driver-specific power index.
  3. If separate armed and disarmed controls are available, set both and check the values reported by the unit. Use the radio vendor’s limits and confirm that the supply and cooling are adequate.

Historical measurements below are specific to the tested adapter and firmware.
