An Inovato Quadra Linux computer can be used to build a Ham Clock device for the Ham Shack. This inexpensive $40 computer provides a low cost alternative to the Raspberry Pi. The YouTube "Ham Clock. Installing, Configuring, and Walkthrough- Inovato Quadra for Ham Radio" by "Ham Radio Dude" W3DJS, looks at this alternative approach. Most of this video is about installing Ham Clock.The device does not appear on Amazon but can be found on the manufacturers web page: www.inovato.com
