Superstar 121 Talkback help
- Thread starter dipd1108
- Start date
Take audio from R160-C126 Junction and feed to IC4 pin 4 via 1uF cap and 100k potentiometer to set desired level.
You forgot to ground the junction of R197 (10k) and D80 (Anode, or non-bar end). This turns the Mute function off when in TX. Can switch on and off this way.
I have noticed with this mod that the volume controll on the radio changes the volume of the talkback. I wonder if relay talkback will help the situation?
