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.

Hello radsel,

sorry, but in moment I have no time to draw the circuits, because I have to finish a scheduled work until saturday.

here I give you the datasheeet from my server database. Look at page 13 to 15. There is the description and 3 different circuits for sweeper.

If you have questions, you can ask me.
