Ham Radio : External Controller

I began my Arduino based project about 7 years ago.

I was a relatively new Operator, with an equally shinny new radio, an Icom 7300 that I’d bought in late 2016.   Unlike historic transceivers, the functionality of many of the buttons and switches normally associated with operating a Ham Radio were provided via a touch screen interface.  That was fine, except that I soon found frequent pecking at the screen a little annoying.  
Fortunately, most of the “controls” and their attributes are accessible via a serial communications protocol which required a small hardware interface and initially just a little software for an Arduino.  I soon had a few buttons which could change Modes ( LSB, USB, AM, FM ) and later Bands ( 160, 80, 40, 20 metres ) too.

I’m happy to share more detail about progress and where it’s heading, in the mean time attached is a brief video
