DDS

Inexpensive AD9850 DDS boards on eBay

Hi everyone.

No updates for a while. We're getting ready to move house so I've been busy with lots of things around that.

Thanks to those who have emailed me reporting that they've built the Arduino DDS-60 controller.

An Arduino based DDS-60 controller

A recent project has been the building of a digital VFO based around the DDS-60 kit and Arduino controller. It's a useful thing to have either as part of a homebrew transmitter or transceiver or as a piece of test equipment. It can generate RF from 1 to 60 MHz in 1 Hz steps with the stability of a crystal oscillator and can run as a QRSS beacon. It's nothing particularly original and it's not rocket science but it might be helpful for someone wanting to get started with DDS and microcontrollers. It's still a work in progress and I'll be happy if anyone wants to contribute ideas or discussion.
