Really, to all you guys:

There is sense, and there is non-sense here...

Never doubted you ALL had the the sense, just pleased you can enjoy a bit of
non-sense...

And, yes, the first time I found out I had to increase effective radiated
power by a factor of 4 to achieve a factor of 2 on someones S-Meter--I was
disapointed--not sure I have fully recoved from the meaning of that to this
very day--frankly, I expected more... I expect if I consulted a
psychiatrist on all this--he would, most likely, chalk it up to "penis
envy"... and that is why I have not... grin

Warmest regards,
John

Just to get a little context here. . .

Years ago when I was a little bored, I determined that the ratio of the
light output from a common two cell flashlight to the entire light output
of the Sun is a mere 280 dB (10^28). So if you attenuate the Sun by 280 dB
you get the light of a flashlight beam. Well now, if you took that
flashlight beam and attenuated it again by the same amount, then did that
again, and again, 14 times altogether, you still wouldn't quite have
totaled 4000 dB. It's a staggering number, incomprehensible except by some
pretty abstract thinking. It's real, though. I remember reading a paper
long ago about transatlantic cables, and those are the numbers they work
with.
