If my recollection is right, Yuri presented a photo of a loading coil in

Their readings were significantly different.

Hi Richard,

The astonishment arises from this commonplace being tarted up as a
revelation.

As for go/no-go sieves, mine is does it make more than a dB
difference? In this case, barely 0.5dB.

So as a metrologist, plus or minus a dB is good enough? Do you use the
number 3 for Pi? That's only .02 dB off.

Heck, Pi is only 0.63 dB higher than e so they are
virtually interchangeable.

Some state (Tennessee?) once tried to pass a state law
requiring Pi to equal 3.00.

Hi Jim,

Error is a fact of life. My sieve of "does it make more than a dB
difference" is not a statement of error however.

A simple example of error is found in
That's only .02 dB off.

:-) What decimal fraction of a tenth of a Bel do you think the ratio
Pi/3 represents, Richard?

Seventy third's de AC6XG

It only matters if you put your lips to Pi.

The difference between .2 and .02 is less than a dB, so that falls below
your 1 dB threshold. ;-)
