RE:  Special Prefixes - 30 March to 30 May - 
     Pr‚fixes sp‚ciaux - le 30 mars au 30 mai

On 19 February 1996, Industry Canada Quebec Region authorised all
Canadian Radio Amateurs to use special prefixes to mark the 50th
anniversary of UNICEF.  UNICEF is the United Nations agency
concerned with the protection of children victimised by war.

le 19 f‚vrier 1996, Industrie Canada r‚gion du Qu‚bec a autoris‚
tous les radio amateurs canadiens … utiliser pr‚fixes sp‚ciaux …
commemmorer la cinqantiŠme anniversaire de l'UNICEF. L'UNICEF est
l'agence de l'Organisme des nations unies qui se concerne de la
protection des enfants victimis‚ par la guerre. 

>From 0000UTC 30 March until 2359UTC 30 May, Canadian Amateurs may
replace their normal callsign prefix with a special prefix as
follows:

Du 0000TUC 30 mars au 2359TUC le 30 mai, les radio amateurs canadiens
peuvent remplacer le pr‚fixe ordinaire avec un pr‚fixe sp‚cial
comme le suit:

Warm, dry days are the noisiest; cold, damp ones are the quietest.  Which is
why (this is true!) I moved to Seattle.  Most of the time it's whisper
quiet.  Unfortunately, being this far north, quietness also includes the DX.

Subject: Matching Transformer for Quad
Message-ID: <14A8016517E at btv0g3.nov.uni-bayreuth.de>

Hi Contesters,

it=92s time for me to set up a new cubical quad antenna. After 15 years
my good old HYGAIN 244 quad passed away due to storms and corrosion.
The output of my cubical quad manufacturers search brought the result
that HY GAIN don=92t longer produce the quad. There are several quad
manufacturers in business. So I ordered some catalogues. Currently I
have two catalogues from LBA (Lightning Bolt Antennas) and a company
called CUBEX. I intend to buy a 5 band quad antenna. Both
manufacturers offer 5 band quads. LBA quads are the cheaper ones. With
my HY GAIN 244 quad it was no problem to feed the antenna with 1 coax
cable for 10/15 and 20 m. This quad worked with a superb gamma
matching whitout interaction.

LBA and Cubex quads are availlable with a matching transformer.The
antenna is fed with a single feed line. It has a balumn/transformer
arrangement that is evidently a toroid 1:1 arrangement with longscrews
sticking out where you put the elements on and have washers between
them. Also an SO-259 coax fitting for the coax to connect to. Simple
and very effective.

KI7M reported me that one thing !SURPRIZED! him about the LBA quad,
when he put it up all the bands had near perfect SWR! He has never
seen this with any other quad. It makes him want to remove the
transformer and feed the elements direct with the coax to see what
difference that might make. Just too good to be true.

K5ESW reported:

There is probably interaction. When you consider that a 20M element
will be two wavelengths on 10M, you can see why. The 20M element will
have an impedance on 10 that will be a close match, and therefore take
current.

Since all driven elements are connected together, current will flow
from the source into each element depending on the impedance at the
particular frequence of the source.

The question he has not yet answered, is what is the interraction, of
just having the elements there (not physically connected).

He also found some interraction at 12M, but not as bad as on 10M.

So I=92m a little bit confused. Does anybody made the same experiences
with using a matching transformer?? Are there any other quad producers
offering quads with gamma match?? Is a matching transformer as good as
single feed lines for each band? If the machting transformer effects
the gain of the quad it is  inevitable for me to install a remote
switch to avoid five additional coax cables.

Your comments are apreciated very much!

Hello Contesters!

Here the score of my fun entry for the ARRL CW Contest single band 20m.
I was only QRV on Saturday from 12.00 to 18.30 on Saturday and about two
hours on Sunday.

The Equipment was a FT990 with 100W and a KT34A up about 10m. The Call was
DL1EFD/a. For those who do not know, the /a means "alternative fixed QTH".

I made 207 QSOs and worked 37 states and provinces, giveing a total of
22.977 points.

Best 73 es gl to all de Carsten, DL1EFD
