Don't think mot combines PTT on tx audio line. They often will put regulated + voltage on Mic line to power hand mics that need power. A small cap will isolate the +v off the mic hi line. OT2 might already have a cap on mic input, not sure. Red - Speaker White - Mic Blue - PTT (if used) Black - Ground
