10.5 TX LEVEL METER CALIBRATION
This process aligns the metering of the transmit level with the actual output of the amplifier. This only
needs to be done if the front (digital) or rear (analog) module is changed or if the transmit level
potentiometer on the rear of the amplifier is adjusted. The process consists of enabling the transmitter
on the digital board to output a full scale signal (10 Watts) and then adjusting the amplifier output until
