Tuning SWR for a receiver - was RE: [Scan-DC] on glass

[Glenn Morris]

BlankThere are devices that are used for tuning antennas well up into the
GHz range. As Andy said, they are low power emitters. Mine had an analog
(printed graph) frequency range and the needle moved to show the notch that
the antenna best fit. I would then adjust the antenna to match the range I
needed it to cover. Unfortunately, I can no longer remember the manufacturer
of the device. It's been too long. (Sometimes this morning is too long!)

In any bureaucracy, the people devoted to the benefit of the bureaucracy
itself always get in control and those dedicated to the goals the
bureaucracy is supposed to accomplish have less and less influence, and
sometimes are eliminated entirely. - Pournelle's Iron Law of Bureaucracy
