IC-720 CAT Control using Arduino Nano

Alan AG7XS


If anyone is interested I put a couple of posts up on the  Icom  IC720  io/group about using an Arduino Nano to control an IC-720 via the 24 pin connector on the back by emulating an IC-746 on the Nano and then converting the command to 4 bit parallel format with appropriate DBC and RT signals.  Audio is through a USB Sound Dongle to a MacBook Air.

Here is a video of it working with WSJT-X.
