Telemobile HX340 external mic/ptt


After some blind testing and a lot of debugging:


 
...here'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!
