Great product  Time owned: 0 to 3 months
I own two vintage radios, a HW-16 and a Johnson Viking Adventurer. Both chirped on most crystals. I was looking at picking up a used HG-10 or similar tube VFO. But they are going for over $100 and some of them need a lot of TLC. So for $79 I ordered Doug's newest DDS VFO.

This is a nice accessory. It went together easily enough (carefully following the step by step check outs) but the LED didn't show any activity. A couple of emails and the problem was found and fixed. My fault. Then I went to Dr Greg Latta's home page and found that he had built this same VFO and has excellent documentation on his building steps, which I followed. If you get one of these visit his webpage.

Adding a buffer amp, built Manhattan style and a step up voltage transformer allows me to drive both old rigs to the highest frequency. Two big advantages: accurate frequency readout and no chirp at all. These are now my daily drivers and I am considering getting another VFO to use with DC receiver projects. Highly recommended for quality and support.  
Product is in production.
