This month we start with a project from Luc Decroos, ON7DQ. Two of Luc's other projects were featured in my March 2019 CQ column. Luc's new project is the KX3 Memory Commander, a small external 6-button controller for the Elecraft KX3 to send any of six CW or Data stored messages or two recorded SSB messages. This is an easy-to-build Arduino project with minimal parts but a lot of useful features. First, it lets you send the messages by simply pressing one button for each message instead of the two buttons required on the radio. In addition, it allows you to avoid accidental changes of other radio parameters caused by not pressing buttons in the correct order. It also allows you to place the box at a convenient location and to fully document the contents of each message directly next to the corresponding button.
