The Transmitter Controller has a digital panel meter which displays Forward RF 

Power and Reverse RF Power as detected by the RF power sampler attached to the 

end of the combiner. The reading on the display is determined by the setting of the 

selector switch and accompaning green LED indicator. The readings are in 

KiloWatts and have an accuracy of better that 2%. However, it is recommended that 

an external watt meter be used for a more accurate reading. See illustration 3-7 for 
