optimizing transmit Power

The DRH-01-100 is factory tuned to achieve a minimum of 100 Watts RF 

output across the full band of the repeater (136 - 174 MHz). RF power 

can be adjusted to a lower output on your operating frequency within 

the parameters of the power amplifier. The minimum power output of the 

DRH-01-100 is approximately 50 Watts.

To access the DRH-01-100 transmit power

notE: Changing the power settings at one frequency may cause 

degraded performance at other frequencies. If the operating 

frequency is changed the RF power must be readjusted for that 

frequency.

To meet the minimum 100 watts specification the power DAC 

should be reset to its original value prior to changing the operating 

frequency.
