[TenTec] which side

The April article in QST is sometimes no more than a stray or similar short
item.  It's there, you just have to look for it.

'tis a shame, they've had some classic suckers over the years, and I'll
admit that I've fallen for one or two from time to time.  I think my
all-time favorite was Suppressed Sideband AM, but the Laser Antenna Elements
comes close.  And I really, really miss the annual DXH&PDS meeting in "How's
DX," but that's another story.

CQ also used to have an annual article, I don't know if they still keep up
with the tradition.

At least we still have the Poisson d'Avril Contest, which of course K1DG
wins every year.

I nominate Larson to be the author of the next April Fool article in QST.  I
bet he would write a good one.  Or have they quit running them?  There was a
problem several years ago because there were a few people who actually tried
to build whatever crazy thing was described.  A few months later the
Correspondence column included some angry letters from hams who had been
fooled.  It was great.  Don't know if that annual tradition has continued or
not.

Ok here's how it's determined. In electronic technology, you use
the "Left hand rule" to determine the north pole of an electromagnet. You
wrap the fingers of your left hand around the coil in the direction of
the current and stick out your thumb. The thumb end of the coil is the
north pole.
For ham rigs, we do just the opposite to determine the side of the rig
most likely to react to a magnetic field. In other words, we use the left
hand rule in reverse.
Note the direction of the current flowing into the Omni VI from the  +12V
lead (RED). Of course, current flows away from the radio so place your
hand (under) the red wire and point your thumb in that general direction.
Your knuckles will then point in the direction of maximum magnetic
suseptability.
Now of course we know this rule only holds true north of the equator.
Below the equator we must reverse all the above.
If this high tec methodology proves excessively complex then one could
always revert to the experimental method whereby one trys the supply on
one side of the Omni and if that doesn't sound right, try it on the
other. But we are way beyond that.
