Anyone got a circuit for wobbulator (or an instrument for sale in
Australia)?

What frequency range do you need it to sweep?

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.
