of Hamfests, and stuff that got away...
This weekend (staring Fri afternoon, thru Saturday) 'the big' New England
Hamfest/flea, at Rochester, NH will be on. (I'll try to find a tesla T to
wear, I'll be gone by noon Sattiday).
As to 'things getting scrapped, i got, too late to act on, or share, a flyer
for the 'dispersal auction' of the equipment from the now defunct Super
Conducting Super Collider.... THAT would have been fun.
======================
A small comment on the way components work in the real world. I suspect
lots of folk know this, but it may be helpful to make it explicit:
Things Change With Frequency.
(Thats too broad to be useful so let me give an example.)
Take a paper/oil cap, say one designed for power factor correction. It not
only gets lossy as frequency goes up, at some point it STOPS being a cap.
It becomes an inductor. Really. Same is true of all caps (and all components,
to some extent. The exact freq varies with the design of the cap (or whatever).
I have put a cap, that i was using for RF bypass, on a tracking gen/spectrum
analyser rig and watched it resonate, all by itself, at 30 MHz or so. (That
was a smallish cap, on the order .001 uF. I was using it below 30 MHz,
so that was ok...)
A standard 'trick', if wide band performance is important, is to pu a low value
cap in parallel with a high value cap. That way, as the high value cap gets
lossy/up capacitive, the low value cap will still look like a cap. The combo
will still resonate SOMEWHERE, but at a higher freq.)
(If that collection of tesal papere IS for sale, lets start a collection of
cash....)
