W6PQL 23cm Beacon Project

This page details the construction and operation of a 23cm (1296 MHz) beacon designed by W6PQL. The beacon utilizes a PIC microcontroller (16F628A) to generate CW and FSK keying for a crystal oscillator, followed by frequency multiplication and amplification. Key components include a 1296 MHz crystal oscillator, a series of frequency doublers and triplers, and a power amplifier stage using a Mitsubishi M57762 module, capable of producing 10 watts output. The design focuses on stability and reliability for continuous operation. The microcontroller code, written in assembly, is provided, allowing for customization of the beacon's callsign and message. The beacon is intended for amateur radio operators interested in microwave propagation studies and equipment testing on the 23cm band. Schematics, parts lists, and construction notes are included to guide builders through the project.
