2207? I assume that is a partial component number? If you want some help, why not give a complete part number?

Hello Keith,

I think radsel means the XR2207 from EXAR. This is a voltage controlled oscillator.

Hello radsel,

do you mean XR2207 from EXAR?

This IC is discontinued for a long time. You can only get a datasheet here.
Look at page 13 to 15. There you find a instruction to build a sweeper.
