[Elecraft] K1 DDS VFO Retrofit?

That sounds like a pretty neat idea.

There are a couple of challenges around bandswitching, though.  The K1 has a
bunch of processors in it, apparently to help with the parts count and board
interconnections.  Somehow, you would want to communicate the K1's band
position back to the processor controlling the DDS (or vice versa).  Since
Elecraft doesn't publish their source, this might be a bit of a challenge.
I suppose you could just have a band button on your DDS controller and push
it when you pushed the K1's band button, but it seems like it would be nice
to get it all integrated.  To make that happen will take a fair bit of
reverse engineering.

Still, sounds like a fun experiment if I could ever find the time <g>.  I
actually have the predecessor card to the DDS daughtercard laying on top of
my K1.  Never occurred to me to merge them, but I could see some benefits!
