[Premium-Rx] Receiver Frequency Display Accuracy & Calibration

[Gary Mitchelson - N3JPU]

Well the original question was how to do this "without the use of
specialized equipment". My answer states this is a way to do it without
calibrated equipment.

I'd prefer to do it with calibrated and accurate equipment if I have it
available, a lot of people do not have this luxury.

It sounds great.
I hope your arrangement is accurate and calibrated,
and it performs to the makers specs and tolerances.

I have a deep misstrust of PC measuring systems,
as I have been caught before,
when software and hardware claim accuracies,
which vary with PC interrupts,
or are interploated between samples.
