LT Spice refuses to cooperate. It gets jealous when I am too clever at
fooling it, and stalls or throws errors on random modes.

Now I'm doing the DDS math in PowerBasic and making .WAV files, and
letting LT import them for post filtering and plotting and FFTs.

I've just about decided that the academics and RF s-param boys have
over-complicated the DDS situation. If all I need is a digital clock,
I don't much care about all those radio things.
