This is a request to any readers of r.r.a.a who are
capable of performing the experiment that I performed.

Use the EXCEL file at:

http://www.w5dxp.com/CoilZ0VF.xls

to estimate the Z0 of your test coil. If the test entry
is greater than 1.0, try another coil.

Here is the test setup using a 75m Texas Bugcatcher coil:

Using a 50 ohm source, install an autotransformer to
achieve the Z0 of the test coil on its output.

Load the test coil with a non-inductive resistance
equal to its Z0 value.

This will ensure that most of the current flowing
through the coil is traveling-wave current and not
standing-wave current.

Report the phase shift through the test coil.

This is an easy test to do. Of course, none of the
resident gurus will run the test or report the results
if they do run the test because it will prove their
old wives' tale to be wrong.
