External key pad for ICOM IC-705
thingiverse
In chapter 13-2, [KEY] of the Basic Manual you can find a discription of an external keypad. The wiring is simple. In addition to the keypad a paddle or straight key has to be connected to the key connector of the IC-705. Therefore my keypad has two femal socket jacks 3.5 mm which are parallel connected. One for a 3-wire (stereo) cable to the transceiver and one for the paddle. I found simple keys at https://www.ebay.com/itm/254253094621 All other parts I found in my spare part or tinker box.
