AUDIO1, AUDIO2, DVM (IC2/pin 23, 24, 25) each needs biased with half the AREF voltage (voltage divider 2x 10k resistors).
The inputs are disconnected from existing circuit and fed through a 0.1uF capacitor from respectively IC5/pin 7, IC5/pin 1 (OpAMP I/Q inputs) and IC5/pin 18 (DAH).
IC2/pin 25 (DVM) might still be connected to D6 to support CAT interface.
-
DAH line is pulled-up with 10k to AVCC, and terminated with 10nF capacitor to GND; so that the microphone is biased.
R7, R10 increased to 82k; C4, C7 is decreased to 1nF.
