My favorite low tech dummy load is the one my father
came up with: a couple of
resistors (carbon composite is best, carbon film or metal film will do), 1-2 watt size,
in a jar filled with water. Works just fine for 100 watts or so, and is useable not
just
for power supplies but for HF transmitter testing.
Why am I thinking of the Heathkit Cantenna?
