Telemobile HX340 external mic/ptt

After some blind testing and a lot of debugging:'s the external mic/ptt schematic for the Telemobile HX-340 handie

Without a schematic of the radio I have no idea if this is the best way for connecting an external mic/ptt but, anyhow, it worked.
Audio is not perfect but workable and can be tailored with a better mic or slight change on the bypass cap.

Have a nice weekend!
