The 3.5mm and 2.5mm connectors are not compatible with "portable" Speaker-Microphones (10mm / 11mm spacing). Neither mechanically nor electrically (pinning).
You can combine a speakerless microphone (modular RJ45) with a loudspeaker (3.5mm) or you can use a headset (earphone + mic + PTT; 2.5mm).
The old kenwood pinning only allow you to use only a such speaker mic. You can't use 2 separate components with it. So I decide to go to the RJ45 - I already had on my previous prototype (DV-ATRX).
