My friend Art, a radio amateur, built
a transmitter for operation on the
70 cm band (420-450 MHz),
but it didn’t work. There was
plenty of RF drive into the final tripler, but the output was
very low. Ed, his friend, came over to see the new rig.
“You’re too neat, Art!” commented Ed.
“Don’t let my wife hear you say that! Whatever do you
mean?” asked Art.
“Look at your wiring. It’s all neatly bundled into the corners
of the chassis, with nice right-angle bends. That’s okay for
the power wiring, but not for the RF lines. Connect them
directly by the shortest, straightest route.”
Later that night, Art reworked the RF wiring in his new
transmitter and turned it on. The output power was what it
“Well I’ll be (expletive deleted)!” Art exclaimed.
