MICROCONTROLLERS IN AMATEUR RADIO
his month we start with three projects that focus not on circuits with microcontrollers in them, but projects that control the microcontrollers already built into our ham rigs. The common thread in all of these projects is a matrix of resistors and switches that provides a specific ohmic value to the radio, triggering a response by the radio. This response can be sending a keyer memory, changing a frequency, or — in the case of the Kenwood project
