I like your baking pan setup as well! Will a Kilowatt
allow you to bake brownies!

Did I mention I also have a couple of Slinkys? Am I desperate or what?


Eh, the slinky concept may not be so desperate in its most serious
application(s). Some years ago when my company was equiping a new Navy test
facility along the Pacific Coast in San Diego, we met a designer who
demonstrated a vertical antenna that the Navy was already buying.

It used a compact log spiral counterpoise of multiple wires. The vertical
radiatior was a "Slinky" element which was raised or lowered within its
(35'?) housing by a motor-driven reel and a nylon rope. It had programmable
memory tuning or, screwdriver-style, you could just run the slinky up or
down to hit the spot you wanted. That day, I recall hearing WWV on more
different frequencies than ever before.

$10,000 in the 1980's.
