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:
