This page is not maintained and is here for historical reference. The project is way out of date and has been abandoned for now.
This project began as one of those "Here's a neat chip, what can we do with it?" conversations and grew from there. The heart of the beacon is a relatively new Direct Digital Synthesis(DDS) chip from Analog Devices. The original idea was to use some of the unique features of this DDS chip to implement a simple FSK441 Meteor Scatter beacon. From there it turned into a much more capable and "versatile" signal source.
The VersaBeacon is a frequency agile, modulation agile RF source using a DDS chip and minimal support circuitry. It covers a frequency span of 1MHz to 150MHz in 1 Hz steps and provides a variety of modulations including:
