but the PSK31 Audio Beacon has lasting value for the PSK31 enthusiast.€ The au-dio tones generated by the Beacon can be presented as input to any SSB transmit-ter — a Warbler, PSK-20, PSK-40, or even a Yaesu FT-1000MP.€ Thus, a PSKer can easily put a beacon signal on the air for all the same reasons that CW beacons are

The PSK31 Audio Beacon is an easy, fun and intriguingly useful project that has evolved from an ongoing design effort to reduce the complexity of a PSK31 controller. A conventional PC typically provides the relatively intensive computing power required for PSK31 modulation and demodulation. With this Beacon project, however, the PSK31 ...

The data-driven audio waveform is fed to an amplifier IC that drives a speaker - and voila, the familiar and melodious PSK31 warble is able to be heard! When presented as input to a PSK31 receiving system such as DigiPan, these modulated audio tones are decoded and the programmed beacon string is displayed. A keyboard or data terminal may also ...

The Audio Beacon features PSK31 encoding and audio waveform generation using a single-chip SX28 RISC microcontroller operating at 50 MHz. The beacon has a choice of three base carrier audio frequencies, namely: 500 Hz, 1 kHz, and 2 kHz. As an added bonus, students are introduced to RF amplifier concepts by taking the output from the audio ...

PSK31 Beacon. The Mk2 beacon keyer is a self contained PCB roughly 90 x 65mm. The beacon texts are user programmable via the RS232 serial port. The keyer generates AF tones for both PSK31 and RTTY. The audio tone output level is adjustable up to 3v p-p. Beacons may be in 50 baud RTTY (170Hz shift) or PSK31.
