Microphone Switching for Fun and Profit

When I started in amateur radio, I did the simplest of things – used the hand mic plugged into the front of the rig. Over time, I drifted away from radio usage for a bit and then came back into it (that’s a story for another post.) When I did, I started to make my shack more complex and versatile, and even added new radios for more functionality. Now I had the problem of having different ways of talking into different radios, and I didn’t like that as much. So I designed a switch box that could take some inputs and mix up the outputs to make things more convenient for how I like to operate. I had someone on my radio club email list ask about a product that could do a similar thing, and I mentioned that I built one for not that much time or money. Since he was interested in more information, I wrote the whole thing up as a nice article. And now, I present it to you, my Home-Made Microphone Switch.
