Hey, kaos513....
check the voltages on IC4 (TA7222AP) in both receive and transmit and let me know what the they are.

(PIN 9) 6.9V RX 6.4V TX
(PIN 8) GROUND
(PIN 7) GROUND
(PIN 6) 1.9V RX 1.97V TX
(PIN 5) 1.9V RX 1.97V TX
(PIN 4) 12mV RX 102mV TX
(PIN 3) 15mV RX 100mV TX
(PIN 2) 6.6v RX 6.5V TX
(PIN 1) 13.7V RX 12.8V TX
-75

Pin 10 is only reading like 12.32 vdc when I tx goes down 12.22vdc all other pins are close to your readings
