81. Remove resistor R27 (1Kohm) on AF-AVR unit (X49-1080-00).2. Install a 10Kohm resistor on foil side of AF-AVR unit. See figure 1.3. Install a 1 Kohm resistor on RIT control. See figure 2.4. Install a capacitor (3.3uF - 10uF) between RIT control and ground. See figure 2.5. Adjust VR-2 on AF-AVR unit (X49-1080-00) for the same frequency as thecenter position of the RIT control.Microphone input attenuator for TS-820Author: Trio-Kenwood Communication, inc.Service bulletin no. 14 (16-2-1977)When using a high output microphone (i.e. Shure 444), it is very likely that there will bedistortion of the transmitted audio if the processor is used. The reason the distortionoccurs is because the processor is between the first microphone amplifier and themicrophone gain control. The installation of one of the attenuators shown below willreduce the microphone input to a level that will not cause RF speech processordistortion. The attenuator figures are approximate.
