ICOM 756ProIII Memory Keyer

So I have been wanting to do this for a while and finally got around to it. I have long looked at the I-Mate but never wanted the price for what it did. So I went about hacking up my own interface and here it is!

K7MHI Button Box for ICOM 756 Pro3

The button box has memory keys for contesting as well as a PTT button, frequency up and down buttons, and the switch is to disconnect the MIC from my Heil ProSet Plus, I do this because I run my Rigblaster Advantage directly to the rear accessory port so I don't need to mess with things going digital. However using that port opens the mic on the front jack... this was my workaround!
