Here the value should be modified to 130% (the parameter step of Tiantun setting is 5, so choose an approximate value of 130).
The default factory parameter of this function is NO, and the adjustable range is NO/YES
ÿ
The calculation formula is:
This parameter affects the later tuning speed, it is generally recommended to set it to NO to save power.
2.0÷1.5x100=130
11÷10x100=110
ÿ
Real standing wave value ÷ local adjustment display value x100= set value
When this parameter is currently YES, the system will automatically switch the signal relay to the pull-in state after power-on, and the radio will
The signal will pass through the internal capacitor circuit of the tuner, and a relay will be generated to consume current; NO will default the relay to
For example, when the radio is transmitting, the screen of the tuner shows that the standing wave is 2.0, but it is 1.5 when tested with a professional power meter. Therefore,
In the disconnected state, the radio signal does not pass through the capacitor circuit in the standby state.
The default factory parameter of this function is 100%, and the adjustable range is 60%-150%
