I just bought one of these. I hope to hook it up to an Arduino and turn it into a VFO. Or a signal generator. Six bucks!

Hi Bill, You can find Arduino code to use the AD9850 for WSPR or QRSS here: 73, Gene W3PM
I would prefer to thank you for the efforts you might have created in writing this article. I’m hoping the same best get the job done from you in the long term as well. In fact your creative writing abilities has inspired me to start my personal Blog Engine blog now.
Bill, I don’t know what happened to the URL in my first comment. It is http://www.knology.net/~gmarcus/ 73, Gene W3PM
Hello, eBay is full of those modules, in fact the strange Engrish sounds like directly lifted from many of the Chinese auctions selling this. Is this one from Amazon actually any good? (distortion, noise, etc.) Regards, Jan
FB Bill. The DDS modules are a lot of fun, and really easy to get running with an Arduino. http://www.usedradiomall.com/dds-update/ After testing with an Arduino, I used the module as a basis for a carrier generator for an AM transmitter. I’m using an ATTiny84 to control it in this case. http://youtu.be/1hcdbFBY5VY 73, W6CSN
