    7.4 TX Gain 7.4 TX Gain TX gain is adjusted by using the potentiometers tabulated below. Weak audio is often caused by the transmitter gain being set too low. Excessive pickup of background noise is often caused by the microphone gain being set too high. See Fig. 7.5.2 for the location of the adjusters.
