The Arduino analogue inputs provide 1024 level discrimination.
Translated to +/- 1000Hz that equates to 2Hz steps. I don't know why
that would be considered not smooth enough?
I sent you the source code by private email yesterday.

> Steve, I've run that idea by a few Arduino guys including AD7C himself. They say yes, you can use one of the analog pins and you can "map" the 0-5VDC to say, an offset of +/- 1000 Hz but they say it's not smooth enough to use as RIT. I would like to try but I don't know enough about writing the code to add that function.
