...well, they didn't call it a varactor, but that's the modern equivalent. What
it is is a voice coil and magnet assembly, but instead of driving a speaker it
moves a small brass collar up and down around two plates of a capacitor. It
could be used to generate direct FM by hooking it across a VFO tuned circuit.
Or make a sweep generator!
It is about 3" x 3" x 3" and weighs about 3-1/2 pounds. I will send it to
anyone who wants to pay the postage from 93705. I haven't tried it, but it
looks to be in good condition -- the coil moves freely and the whole thing is
relatively clean. Somebody must need this.
