HQ stations in IARU HF Co...

Good info on HQ multipliers in the IARU contest; I'll be on.  (Blatent
commercial follows:  Work me!)

Aside from the list of callsigns you sent, which were from previous year's
contests, and a few obvious ones, how would one identify some of these other
HQ stations?  I wouldn't guess that LU4AA or IU2A are mults separate from
their respective countries.  Makes using logging software kinda tricky also.

If the K1KI source could publish a list of other HQ callsigns that were on in
this year's contest, that would be most helpful---especially if that could be
done shortly after the fray is over.

As promised, here is your first, pre-deadline report of claimed scores!  If
you are not listed, it means I haven't received your entry yet, so get busy
and sent to me.  Likewise if the data is wrong.

The new group lead by AD5Q, who one of only three to have sent all the
requested info in correctly on the first attempt, has a commanding lead for
the Multi-Single plaque and similarly W8QLS for the Multi-Single plaque.  

I sure pays to get out there and join in with the big local group; just look
at all the help they got!  

The only Clean Sweep goes to Check Log W6QHS.  Come on now people, we've got
a hundred of those little BROOM and DUSTPAN awards on order!

Lucky for you that the deadline to send in your entry isn't 'til a whole
week from Saturday!  So send me your entry by the new deadline of 15 July
and join in the fun.

Hi Ed!
I'm pleased you have taken my comments on the design of serious 
competitive HF antenna systems in the positive light in which they were 

A free space wavelength on 80M is 280 feet, and the top of my horiz
polarized quads is at 175 ft, so they are a mere 5/8 wavelength high at 
the top!

By the way, an alternative way to look at the lobe splitting problem is 
to think about the distribution of power across the surface of a sphere.
A lossless source illuminating a sphere is a 0 dBi (isotropic) antenna.  
If this same lossless isotropic source is placed at ANY height over a 
perfectly conducting half-space, grating lobes appear, and only one 
quarter of the sphere is illuminated (the lower half of the sphere is 
blocked by the perfectly conducting half-space, and the the energy reflected
from the conducting surface adds to the direct radiation from the source 
(ie produces 6 dB gain when it is exactly in phase), and subtracts (ie 
produces a perfect null when it is 180 degrees out of phase).  This 
grating lobe radiation is exactly what is seen with a Yagi over real 
ground, except the Yagi also has a pattern, which concentrates the 
radiation in the lower forward lobe or lobes (depending on the directivity 
of the Yagi).  No power is lost in the production of grating lobes, 
except that more nulls are produced!  Think about it...

More about vertical polarization later!  There really are reasons why its 
not preferred by serious HF antenna designers, except in very specialized
