What would be a good project for the SI570 chips? I have some that just arrived and it would be nice to have few things;

1. A low cost version that is stand alone and does not need a computer, with simple displays but options for a 2x16 display if it doesn't raise the basic cost too much.
2. A controlled LO for the SoftRock series, since the chips can go to 200+MHz 10M is not a problem since it needs half that frequency. My thoughts in that area is to make the controller respond to the Flex Kenwood CAT command set. It's a well defined set of commands that covers a lot of areas, and it's being expanded to even cover thing like a panadapter display. The oscillator would of course only respond to items that are relavent. A nice addition would be that the oscillator controller would control bandpass filters to match the LO frequency.
3. A general purpose oscillator for the shack, to be used as a signal source, some kind of manual or controlled attenuation of the signal would be mandatory for it to be useful.
