[Elecraft] Dummy load

[Jeremiah J McCarthy]

Popular Electronics published an article in 1970 on how to build a dummy
load into a paint can ala the Heathkit Cantenna...Very simply it
consisted of 2 large copper washers, a short length of 1/2" copper pipe,
and ten 510 ohm, 2 watt composition resistors soldered in parallel
between the two copper washers, which were drilled to accept the resistor
leads...A PL-259 was mounted in the center of the paint can lid and the
pipe/washer/resistor assembly was soldered to and suspended from the
bottom the PL-259...This assembly was immersed in transformer or mineral
oil in the can, raising the power handling from 20 watts to 200 watts...I
built one of these and still use it, although I made mine with twenty
1000 ohm resistors, making it capable of 400 watts...In those days I was
running Drake Twins, rated at 200 watts PEP, and never heated the oil...

I recently saw a variety of 2 watt composition resistors at a flea
market...
