I'm planning on wiring mine so the mic's power up with the CB TX switches, just haven't gotten around to it yet, should be a good rainy day project.
I have thought about the wind noise in the headphones of the 1800 intercomm. Has anyone thought about adding a simple normally open momentary push button inline with the microphone feed line? I don't want to re-invent the wheel if it has already failed. I would think that if you would put this switch in the line, the mic would be off all the time. Then, when the driver or passenger wanted to talk, they could simply push the button which would complete the mic line, and talk. While it wouldn't be a perfect fix, it would be cheap and stop the continuous wind noise problem, or at least I think it would. But, like I said, the simplest does not always work...
