TBS Tracer Manual
Transmission power
The transmitter’s RF output power is highly configurable and can be selected dynamically via the menu.
With 100mW you can achieve 15 km of safe range in rural conditions.
It is recommended to use the dynamic power option. This will allow you to fly at very low power and the
system will increase the power automatically (faster than you can hit the power switch yourself) if you are
about to lose the link.
Some output power restrictions apply depending on the available power source:
Power source
Available output power
USB power input (+5V)
25mW (14dBm)
RC radio power input (+3.5 to +12.6V)
25mW (14dBm), 100mW (20dBm)
To change RF power:
1. Enter the configuration menu/ LUA script select “General”/ “Tracer TX” and “Max Power”
2. Pick the RF output power you require and exit the menu to confirm
3. The change is instant if the required input power is available and can be done at any moment
Every 6 dBm increase in output power results in a doubling of the theoretical possible distance that is
achievable.
If you set a power level that is outside the connected power source, it will still be remembered for later but
the output power will be limited according to the table above.
