I am currently gathering parts for a synthesized DDS VFO as per the James
Hagerty Wa1FFL design. There was an article in QST a few years back about this
kit. I have the PCB, and most of the parts now. The kit comes with info on how
to interface with "boat-anchors". I hope to finish this in the coming months.
The cost is $40.00 for PCB, and a few important chips. Finishing the kit looks
like the total cost is about $125.00 depending on how fancy you make it (like
the chassis selected). The DDS chip can be custom programmed, and I picked 2.5
to 12.5 Mhz. I figure that will allow me to run 160-15 meters on my Central
electronics 20A (beat against 9 mhz). I will have to double the VFO to run 40
meters however ( 9 + 7.29 = 16.29, so I'll double the VFO at 1/2 that..maybe a
push-push doubler).
Sure looking forward to getting away from drifting VFO's, or being
"rock-bound".
