Hi Mike,

Coherence has become a shallow rhyming proof rendered as
"SoThereIt's!" (a mumbled qed). It is a convenience of a special
solution which requires artificial constraints that over the course of
"debate" have become necessary correlatives to a general "law" of
optics. In fact, few have examined what "coherence" actually means,
but instead it has been Xeroxed by Cecil into the argument.

Both Mike and Tom have been able to disconnect this term as one of
necessity for monochromaticity (not required) and instantaneity (also
not required). This lack of requirement (that requirement having been
artificially injected into the discussion) is historically exhibited
in work going beyond 100 years old. The first work was with
sun/starlight that is neither pulsed nor monochromatic, and yet and
all, interference was clearly found which led us to this discussion.

  Unused Antenna Port ?         


Author: Robert11
Date: Mar 9, 2008 10:44

Hello,

I will be using a single antenna going to an A/B switch so I can feed the
antenna to either one of two Scanners (receive only).

Apparently the switch does Not ground the unused port.

Was wondering if having the scanners antenna input jack just "floating"
while the unit is off has the potential for damaging the radio ?

I guess I should also ask the corollary: If the unused scanner is turned On
accidentally, and the port is floating as before, any potential liklihood of
damage for this case ?

Guess I am worried about static buildups, etc.

Thanks,
Bob
