What frequency range do you need it to sweep?

-Joe K9LY

around normal IFs, ir say 450 -470 slectable, typically 455 +- 445 to 465

No takers on this challenge? Should be simple if I knew enough! Some sort
of saw tooth driven variable frequency oscillator. Not a very wide range
either, say plus or minus 20 Kc/s But must of course be absolutely level
over that range.

Think I have just the circuit for you. It was published in the Eddystone
Users Group newsletter about 7 years ago. Send your real email address
to me at k9ly "at" arrl dot net and I'll send you a PDF of the article.
