Hello,
About 10 years ago I modified a Baofeng speaker/mic for use with Remoterig and served me well. But because it was a cheap speaker/mic, it has finally fallen apart.
I found this speaker mic made by Retevis model HK002 for Kenwood that works very well, has good audio, and I sound ok. Use in RRC radio settings, Codec inp gain 5 and Codec inp preamp to "Yes".
Attached is the mod I did. Speaker/Mic found on Amazon (Retevis HK002) , and important is to use hot glue to secure crimp, as the cable is thin and can be a bit loose in RJ45 connector.
Use Kenwood wiring for TS-2000, and additional jumper as indicated in image to pass speaker audio to pin 7.
