              IARU 1995 Contest         IR4T M/S Contest Activity
-----------------------------------------------------------------------------

We will be active during the IARU Contest in the next weekend in a  M/S
category. All band will be checked, also 10 m, seem open around 12.30 Z
with W1 e W3, please look for us on 15 m to schedule on 10m.

Well, the thing is that some people do not want ALL the signal to go in
ONE direction and would rather have the beam pattern all messed up in
exchange to be heard well in two (or more) directions.

For example, in SS from the Midwest on 40M, you would want to "spray"
(KA9FOX quote) your signal.  The low beam goes towards East Coast and
the high beam goes towards the longer path West Coast.  To have two
beams in the same direction can actually be counter-productive.  Sure,
you can be loud in one direction, but everyone else is off the back of
the beam.  And, two beams in this configuration is better than a dipole.
(It's like a high gain dipole with two different take-off angles.)

This also applies to the high bands.  Gary, W9XT, has used this method
for years in the 10M contest (gee Gary, I hope I didn't let the cat out).

And, if you're having problems hearing a weak one, you can always switch
to just a single antenna to peak up the signal in a particular direction.
It's FAR quicker than swinging the beams around which can take 20-60
seconds...enough time to work two more stations!
