https://youtu.be/umpNTNauP_UI am quite end with this remoterig pair with kenwood ts-480.
No mic lead connected in control rcc( pin 3 disconnected), power 5 W, dummyload. micgain 55,pumping noise disappears( when set to ab. 30) when turn micgain lower, can hear that brum still. When processor is on, noise is huge.
This pair were in remoterig for repair and should be okay.
When put microphone straight to radio sound is perfect.
Any hints
I think I forget my remotestation dream
