Simple beacon controller

    Detailed here within is a simple beacon transmitter controller. Originally developed to be integrated into either a 2m or 70cm FM transmitter for use as an aid to propagation investigations, or as part of a hidden transmitter i.e. FOX hunts.

    The beacon controller presents a keyed 600Hz tone at a level suitable for direct connection to the microphone input of most modern commercially built transceivers, a closing contact for transmitter keying, and three indicator LED's to show the controllers current operational status.

Design concept:

    The design concepts primary goals were as follows:
