Transmitter Power

Note

Radio Tuning Procedure
The radio requires two power level adjustments, a high power or rated power
adjustment, and a low power adjustment.
• After POWER tuning, measure and note the DC current to the radio on
each channel in the high power level. These values are needed for the
Current Limit tuning.
• The larger the softpot values, the lower the transmit power.
