A low-cost Arduino project expanding on the button tutorial, where three inputs act as "buttons" generating Morse code on a WOTDUINO. This keyer, costing around £4, offers learning potential and hints at more complex ham radio applications.

This is a contest keyer for the AEA MM-3 Morse Machine. It integrates with OmniRig for your radio's frequency. It has a built in logbook as well as a keyboard keyer. You can also export your log as an .adi or cabrillo format for contest submission. Please find my contact details on QRZ.COM for any suggestions or help 73 ZS6WAR

This page presents a project involving attaching an amateur radio transceiver to an Arduino to create a 'fox' signal for radio direction finding practice. This project can be used to practice direction finding skills by locating a radio transmitter in a hidden location. The project involves transmitting the station ID using Morse code and can be a fun and educational activity for students or hobbyists interested in radio direction finding. The author shares their experience with radio direction finding and provides instructions on how to build the project using a Baofeng UV-3R radio and an Arduino Uno.
