If there is a microphone impedance problem, then the plug is technically not compatible with mil std PTTs. This would be something that United Star would have to change on the radio. But I think that because they have the Kenwood two pin plug and the U-283 plug, both are probably wired into a single circuit. This means that if they changed the impedance of the microphone circuit to match the mil std PTT, it would then not work with standard Kenwood types. So I don't see this happening any time soon (if at all.)
