Internal Adjustments

All internal adjustments are factory set and should not need readjustment under
normal conditions.
1.3

Output Power

The output power is set to the desired level watts by RV2. It determines the
threshold of the ALC voltage which is fed back to the transmitter module to
regulate the power. The output power of standard amplifiers can be set to any
level between 25 and 75 watts. The high power versions with "H" suffix model
numbers can be set between 50 and 100 watts.
