TX audio chain

It started as a simple project to construct a switch box so I could use a single microphone with multiple radios in my home shack. It’s ended (although i’m not sure it will ever end!) with more knobs, buttons, switches and flashing lights that the flight deck of a Dreamliner.

I’m still experimenting and will be posting a walk through soon so stay tuned but for now, here’s a little picture…

Just a quick post about the stock microphone on the Icom IC-7200. If you have a “made in China” version of the HM-36 then you can make your audio a lot better.

Forget messing around with the mods listed over the internet and jump right in with a kit from AB5N. His microphone element along with the associated modifications will transform your HM-36 into a great sounding microphone.

I tried 4 different modifications and the AB5N came out on top. Highly recommended.
