Ever wonder why K1EA/K1AR always win?
There is a vicious conspiracy behind all those victories...(see P.S.)
I recently moved to another QTH about 30 Kms away from my station, at my =
parents home.
Having no radio to distract me I started thinking about the decision maki=
ng process in the CQWW and in any=20
contest in general as far as Running or S&P is concerned.
I believe one must update his decisions every 10 minutes, and you can eit=
her choose to Run or to S&P.
Lets say at the beginning of your next decision your score is:
S0=3DP*Q*M
where P equals points per QSO, Q equals QSOS and M equals multipliers
If you decide to Run for the next 10 minutes at the end of those 10 minut=
es your score will be:
S10R=3DP*(Q+x)*(M+v*x)
where x will be the number of QSOs you will work in the next 10 minutes a=
nd v will be the velocity you will=20
work the multipliers.
If your decision is to S&P your score at the end of those 10 minutes will=
be:
S10S=3DP*(Q+y)(M+y)
where y is the number of new multipliers you found during those 10 next m=
inutes.
If you think S10R will be greater than S10S RUN if not S&P. Sounds easy..=
.doesn=92t it?
In order to calculate the value of x that gives the indifference QSO numb=
er between Run or S&P all we have to=20
do is to equal the two equations:
S10R=3DS10S
P*(Q+x)*(M+v*x)=3DP*(Q+y)(M+y)
resolving the equation in order to x
x =3D (-(Q*v+M)+SQRT((Q*V+M)^2+4*V*(Q*y+y*M+y^2)))/(2*V)
(SQRT=3DSquare Root)
So if you think during the next 10 minutes you can actually work more QSO=
s than x you should RUN otherwise S&P.
Looking at the formula there are two variables you don=92t know upon taki=
ng your decision:
v - Velocity of Multipliers during the next 10 minutes
You don=92t know how many multipliers you would work, in case you
decide=
to Run therefore you must=20
estimate what this number will be. I use the last 500 QSOs to estimate v =
(use the number that gives you the=20
highest correlation, depending upon your location, upon the time during t=
he contest, upon how strong your=20
signal is etc.). Also the historical value of M/Q during the last 12 hour=
s at 12:00, 24:00 36:00 and 48:00 is a=20
good indication. So in the next 10 minutes I assume I will work the same =
proportion of Multipliers per QSO I=20
did in the last 500, for example.
y - Number of Multipliers you are going to work in the next 10 minutes.
You don=92t know how many Multipliers you will work if you decide to
S&P=
therefore you must estimate this=20
number. Of course this depends on how good you are, how many Multipliers =
you already have, how powerful your=20
station is etc. But just for your reference, on Sunday from a DX location=
, after 12:00 if you can find more=20
than 3 new Mults in 10 minutes, that would be really great (PY0FF 95 CW).
Now the K1EA/K1AR Conspiracy.
K1EA/K1AR competition at the East Coast is using CT as their main logging=
program.
They look at CT screen and they can value the time worth in minutes of a =
Multiplier..
So instead of thinking in the next 10 minutes think of time you will spen=
d working a new multiplier or the=20
number of QSOs you can work during that period of time (the rationale beh=
ind it is exactly the same).
How does CT calculate that number?
Well K1EA CT thinks
if you S&P for 1 mult your score at the end will be:
S1S(CT)=3DP*(Q+Y)*(M+Y)
and if you run instead of S&P for 1 Mult
S1R(CT)=3DP*(Q+x)*(M+0)
then for S1R(CT)=3DS1S(CT)
x=3DQ/M+1+1/M
therefore the value in minutes of a multiplier in CT is given by:
(Q/M+1)*(60)/(rate last 100 QSOs)
CT assumes that for y=3D1 x=3D(Q/M+1+1/M)
instead of=20
x =3D (-(Q*v+M)+SQRT((Q*v+M)^2+4*v*(Q*y+y*M+y^2)))/(2*v) =20
Running examples x(CT) is always greater than x for reasonable values of =
v (depending of v, but about 50%=20
greater)
So when you have to make a decision to Run or to S&P and look at the valu=
e of a multiplier in CT you think you=20
have more time to work a multiplier than you really have if you would con=
tinue Running.
If you are a strong believer in conspiracy theories you will think K1EA/K=
1AR use the correct value for the=20
worth in minutes of a Multiplier. Their competition thinking they still h=
ave time available to look for one=20
multipliers in fact don=92t and lose precious QSOs and points S&P when th=
ey should have been Running.
That is why they always win........
P.S. I don=92t believe in conspiracy theories=85

This sounds like the buildup of electrostatic charge on an ungrounded
antenna. I've had similar problems with just the wind blowing in dry air.
I'll bet this is old news to the Colorado contingent ;-) A 100k-ohm,
1/2-watt carbon composition resistor from the antenna to ground will drain
away the static charge without affecting the RF parameters. An RF choke
will do the same thing, providing a DC path to ground.

No, I don't think the two are equally bad. Snow static might be worse and
there are definitely differences between regions in how bad rain static
is. I've seen plenty of lightning in snow storms, by the way. The snow,
because it falls in air of low humidity (the moisture is frozen) has a
better chance to build up charge and hold it. The rate at which
snowflakes hit the antenna seems to me to be lower than for raindrops,
too, introducing another variable, that of rate of charge delivery. (this
is getting too arcane) Also, I think there's plenty of intra- and
inter-cloud electrical discharge in snow clouds.
> 2) Is the "static" due to charges imposed ONTO the element FROM the rain???
The static is the response of the receiver to a transient burst of energy
resulting from the sudden transfer of the charge on the drop or flake to
a surface at a lower potential. i.e., your antenna. Another way of
generating that transient is for the charge to suddenly get "really close"
to the antenna, causing a displacement current in the antenna. Either
way, it's a burst of noise across a wide frequency spectrum. So the
static results from the sudden transfer of charge at or near your antenna.

Subject: Guy wire thread
Message-ID: <199604271555.LAA12612@cais.cais.com>
Steel guy wires loosen up with age due to thermal expansion/contraction.
They need to be adjusted (read: tightened) periodically, probably annually,
if the environment produces winter/cold and summer/hot temperatures. Also,
they will be tighter in the winter than in the summer due the the ambient
temperature and their coefficient of thermal expansion.
Many hams seem to prefer loose guy wires. I don't know why. All of my
mechanical engineering research shows that when things are loose (eg, bolts,
plates, etc) they are subject to other stresses (tension rather than
compression, for example) that might cause the material (steel) to weaken
and potentially break. There is a study about such failures which was done
many years ago that verified this (I don't have the reference).
My research shows me that steel guy wires should be tightened to
approximately 10% of its breaking strength. For my guy wires, 5/16 EHS,
that means about 1200 lbs. Other size guy wires should be tightened
according to their maximum rating as well.
While I have an engineering degree, I'm not a mechanical engineer. So, my
information has been gleened from various texts and discussions. But, my
conclusion is that you want your guys, bolts, nuts, etc., tight, not loose.
If they are loose, you're asking for trouble.
