Leuke buurman..............

I have a qso with a niebor abt 4 houses up from me on ten meters every day on 28.100 MHz and he is abt 300 yards from my ant ,if he is running 100 watts wud that ruin my rig ? i can run the attn. and it helps but im just curious if the 100 wats he is running wud hurt my radio.

Well this feller is 90 years old and he taught me c.w well he is training me ,but i think sometimes he dont know hes running 100 watts,and one time i asked him to turn dwn his pwr and i think i affended him,i dont want to make him mad cuzz then he might not come back to our sked,he is an ww2 vet and was in the invasion of normady and has lots of c.w. exp. and neet to hear some of his storys of the past ,he can get moody sometimes and i dont want to affend him ,he might take it the wrong way wen i ask him to turn it dwn . hee hee .ornary sometimes .
Rem : Why not walk the 300 yards, take a couple of beers with you and that way
you'll a) get the exercise, b) work up a thirst, c) still have your
natter and d) save electricity for both himself and yourself?
Rem : Do you think just a couple of beers would be enough ?
Cheerio from John Snell. / G0RDO

Rem : Use a dummy load on your end as the antenna when you are working your friend. You two are close enuff distance wise that either one of you can hear the other well enough. I have been able to work out to 4 miles or so on a dummy load in the basement with 35 watts or so, accidentally of course. This way you know your front end is safe! 73 Paul WD8OJL

Rem : Part 97, Section 97.313(a) states that "An amateur station must use the
minimum trnasmitter power necessary to carry out the desired
communications."

Morse Code Class from 1941

Rem : Interesting video. I had the pleasure of living across the street from
another 1,000,000 watt VLF transmitter on the Navy Transmitter site in Hawaii.
During installation testing they created homemade lighting with 500,000 volts
that would jump from the top of the 20 foot insulator just outside building to
the ground. It was surprising when I walked into the building for the first
time. The building is the transmitters. When you stand at the control panel
you are actually inside a transmitter. Each stage of the transmitter has door
for the technician to gain access for repairs. It is a standard size door like
you have in your house. The top half of the door is glass with wire between
the layers. The name of each transmitter circuit was on the door for each
stage. This transmitter I believe had 8 rooms from the Oscillator room through
to the Final Amplifier room. The transmitter was connect to an antenna held
up by two 1500 foot towers. Each tower had a 3 person elevator inside of it to
allow civilian riggers to ride up in to do maintenance.
Amazing stuff! W1RO

Deze call komt in NL niet voor

Well..... my station is a HeathKit HW-16 hooked up to a dipole at 25'. I run it "rock-bound" but, more than often, use a HG-10B vfo. If I had my d'ruthers... I'd d'ruther run the same old rig... but one that didn't chirp or shoop. I have a blast with this silly thing!

Obvious anti QRP?

Life is to short for QRP?

The listener to a weak QRP signal deserve the credit for a good qso not de QRPer (pa3egh)

I do not wish to promote QRP or participate in any activity that does so.

I do not find working stations with weak signals unless they are DX stations worthy of such effort.

Rem : Cookie - Why not? - Jack
Rem : My point...there's something for everybody in ham radio & SKCC. To each his/her own.
73's, Tim, KD8GZ,

Rem : Tim, if you find it fun to put out a weak signal for others to try to copy, go for it.

I don't find it fun to have a big tower and beam so that others can turn down their power to the point I can barely hear them and then brag about what great operators they are and how much fun they have. I don't have fun with the three repeats then finally looking up your Name to complete the QSO.

Rem : Cookie...This is a hobby that can be enjoyed many different ways.

Deep Solar Minimum info from NASA

Looks like we're in a record setting low right now. Hmmm.

Rem : I have been enjoying the low sunspot numbers. The low bands have been fun!
However, the astronomer in me is not having fun looking at a blank sun
(of course, there are always prominences you can look at, with a
Hydrogen-Alpha solar scope, no matter what part of the sunspot cycle we are in.)

Sri only in Dutch - The end of Morse-code -

Voor diegene die de OTC-jaardag niet hebben bezocht het volgende bericht.

Door Jan Pieter Oelp, 'JaPiO' PA3CLQ

Geertruidenberg aan de Maas een April 2009

De dood van de Morse-code / Morse code RIP ? eindelijk een feit !

Dit komt niet zo maar uit de lucht vallen, uit twee forums uit de USA die gelekt hebben heb ik vernomen dat de MORSE-code (in feite de Vail code), de American code, Japanese code en andere machine language CW code komt te vervallen.

De verschillende overkoepelende communicatie organisatie n.l.

ARRU, American Radio Relais Unie

IARL, International Amateur Radio Laegue

CFC, Communication Federal Commission

BGSR, Britain Great Society Radio

IUT, International Union of Telecommunication,

hebben unaniem besloten dat de aloude codes niet meer van deze tijd zijn.

Men wil harmonisatie met moderne digitale modes en wensen vanuit de ICT ook met betrekking tot verbindingen via landlijnen zoals internet.

Bij de bestaande morse-code is het aantal tekens variabel en dit strookt niet met de nieuwe digitale gedachte van standaardisering van tekenlengtegelijkheid.

Een en ander voor bevordering en optimaal gebruik van de telecommunicatie-etherinfrastructuur en de best denkbare ordening van het radiospectrum, geldt overigens ook voor de nieuwe code verbindingen via landlijnen (internet) ten aanzien van het onderbrengen van de digitale informatie die via de modernste modulatietechnieken in steeds kortere doch snellere/kleinere timeslots moet worden geïncorporeerd.

Maar ook regulering van (gezien vanuit de nieuwe gedachten voor modern en technisch denken) uitwassen in de vele reeds bestaande vormen van communicatie mogelijkheden heden ten dagen. Dit is slechts één aspect in het grote geheel.

De genoemde organisaties dragen vanuit hun expertise bij aan een mondiaal niveau met betrekking tot beleidsontwikkelingen die gelijke tred moet houden met de snelle technische ontwikkelingen. Het zal duidelijk zijn dat het wettelijk kader daar voor vast moet liggen in de wet op de telecommunicatievoorzieningen (WTV)

De nieuwe code bestaat uit vijf tekens, elk teken kan een punt of een streep zijn zodat we twee tot de macht vijf is tweeëndertig verschillende karakters kunnen vormen.

Ons alfabet heeft zesentwintig letters. De zogenaamde Griekse Y wordt geëlimineerd het gebruik van de letter I en J kunnen worden samengevoegd zodat de letter IJ ontstaat met de zelfde functie als de in de ban gedane Y, totaal dus vijfentwintig letters.

Omdat we ook nog leestekens en cijfers hebben is tweeëndertig verschillende karakters te weinig.

In de vele studies betreffende is tijdens brainstormingsessies voorgesteld (of the record : boze tongen bewerem zuidelijke buren) om de cijfers te spellen, het cijfer 1 wordt dan vervangen door de nieuwe code E E N , cijfer 2 wordt dan geseind als T W E E, het leesteken ? wordt dan als V R A A G T E K E N geseind zijnde tien maal vijf karakters zodat met minder verschillende vijf karakter tekens kan worden volstaan wel ten koste van enige snelheid voor de met name genoemde telegrafisten die dit nog met uit de tijd zijnde handbediende apparatuur zoals een seinsleutel die met een verticale beweging van hand en pols (h&p) twee contacten op elkaar brengt om de gewenste code voort te brengen. Uiteindelijk heeft men na lang beraad, vele vergaderingen en kostbare vlieguren t.a.v het heen en weer vliegen dit voorstel toch maar verworpen.

Leestekens zijn belangrijk daarom is er uiteindelijk gekozen om een LETTERS dan wel FIGURES teken toe te voegen om aan te geven dat de volgende 5 karakters een LETTER of een FIGURE is zoals een cijfer dan wel een leesteken zodat b.v. het cijfer 1 niet als E E N dus uit drie maal vijf is vijftien karakters bestaat maar uit slechts vijf karakters, in feite geheel passend in het nieuwe denken.

Algemeen werd aangenomen dat met de dood van de Morse-code ook deze groep, dit type marconisten vergrijst en uiteindelijk ophoudt te bestaan, men denkt aan een jaartje of zesenzeventig.. Duidelijk heeft men hier de toekomst voor ogen.

Voor de ouwe CW-knarren is deze omwenteling even pijnlijk, maar uit studies en de uit het verleden opgedane ervaring leert dat de overgang weliswaar waarschijnlijk helaas niet voor iedereen vanwege vastgeroeste gewoontes en een mogelijk gebrek aan intellectuele vermogens en aanpassing problemen vanuit een mogelijk moeilijke/arme jeugd of een of andere handicap of iets dergelijks toch een uitdaging zal zijn en zij - de nieuwe technische mensch - het moeizaam maar gestadig eigen zal maken.

Klein voorbeeld ter verduidelijking, de roepnaam HS5HHH bestaat uit 24 dits dit is absoluut absurd en komt met de nieuwe code niet meer voor.

De nieuwe vijf karakter code ziet er als volgt uit :

A of - ..---

B OF ? .--..

C OF : -...-

D OF $ .--.-

E OF 3 .----

F OF ! .-..-

G OF & -.-..

H OF £ --.-.

I OF 8 -..--

J OF " ..-.-

K OF ( ....-

L OF ) -.--.

M OF . --...

N OF , --..-

O OF 9 ---..

P OF 0 -..-.

Q OF 1 ...-.

R OF 4 -.-.-

S .-.--

T OF 5 ----.

U OF 7 ...--

V OF ; -....

W OF 2 ..--.

X OF / .-...

Y OF 6 .-.-.

Z OF " .---.

FIGURES ..-..

LETTERS .....

Meestal begint een oproep of QSO met letters, het zal duidelijk zijn dat er begonnen wordt met het uitzenden van de vijf karakters voor LETTERS het cijfer in de roepnaam zal vooraf moeten gaan door FIGURES gevolgd door het cijfer of cijfers vervolgens door LETTERS en de rest van de letters uit de suffix, lijkt omslachtig voor het handmatig produceren van de code doch een en ander is toch op automatisering van het berichtenverkeer gericht.

A Verry Nice Joke.

I was going to send some comment referencing Dihydrogen monoxide--DHMO.
Several years ago, a middle school student built a science fair exhibit about
how easy it is to mislead people in matters scientific. He collected I don't
recall how many adult signatures on a petition to have the substance banned.
Penn and Teller repeated the experiment for their cable TV show, 'Bovine
Excrement,'--use the blue pages of your inner dictionary for the actual
name--with the same result

Here's a link exposing the 'truth' about it.
http://www.dhmo.org/facts.html <------for the chemistrys among us

Enjoy.
Rem : Also reminds me of the city council (also in CA) that tried to outlaw
the use of dihydrogen oxide.
Luckily this happened on April Fool's day. Obviously written by a ham.
(S)he must be having a great time with it.
73, Neil NG5NG

Rem : DHMO... It was good to laugh at :-) Dihydrogen monoxide (H2O) HI!
And really there are people who can seriously be mislead, even in governmental circles...
I remember 10+ years ago when a documentary film showed a recently
discovered animal, a so called "oil-eater", a rat-sized mammal who could
eat and process waste oil, rubber and other harmful objects. Only weeks
later when the whole Central and Eastern Europe were taling about it
excitedly turned to light that it was a joke only made by some young film makers...
That's life.

This is kinda long but, I decided its time to pull it out again.

Here goes:

8 GOOD REASONS FOR NOT GETTING ON THE AIR

1. I CAN'T COPY VERY WELL
Copy skills get better with time and practice. Nerves is certainly a factor at first. The answer to nerves is exposure. Get on the air and practice those skills. After all, you're not copying vectors for a brain exploration surgeryЕЕjust fun stuff. What if you do miss some? Eh?

2. I MAKE MISTAKES IN SENDING
Who cares? Everyone does! If you show me an op who sends flawless CW, I'll eat my hat. Even keyboarders make mistakes. Its what you do when you make one that is the measure of an op. A good op corrects his mistakes. When you glide past mistakes it leaves the other guy guessing.

3. MY CW IS VERY SLOW
Accuracy transcends speed! Accuracy is absolute, while speed will increase/improve over time. What you DON'T want is to get faster at sending poorly. Fast and poor are an awful twosome. Practice sending well, at a speed which is comfortable for you. You WILL make mistakes,Еjust correct them and move on.

4. I GET LOST IN QSO'S
As many have suggested, by writing down the parts of a typical exchange/qso, you will be better able to get through a qso. Its really funny how few comments are directed to spelling. Spelling slows us down and trips us up in many qso situations. When you practice off-air, its fine to use a sheet of text, but I find that sending as if in a qso is much more helpful. Practice this by sending out of your head. You'll get used to sending off the cuff and your spelling will improve tremendously.
If ragchewing is your goal, keep your exchanges short, at first. Don't try to say too much in one exchange. That way, it will give you time to think about what you'll say next, and will slow the other op down as well. That will make his transmissions easier to copy. Keep it casual, and don't let it become hard work.

5. MY PALMS SWEAT
Keep a hand towel at your operating desk. My palms sweated on my first date too but, it didn't stop me. Remember, no one can see you! Try PRETENDING you're as calm as a cucumber. Think of yourself as a "take charge" op who can handle any situation. As an op thinkest, so shall he be on the air.

One particular activity that improved my confidence and ability to handle most situations was learning traffic handling on the Maryland Slow Net. Net speed was maximum 10 wpm (and flexible), the instructors were patient and considerate. That training gave me the confidence I desperately needed. I'm now an Instructor/NCS on that Net and watch the transformation of new ops from tentative and unsure to ops who would be welcomed on NTS traffic net throughout the country. Its easy and painless and proceeds at the new op's own pace. Even if you don't become an active traffic handler, the training is invaluable for learning general operating practices.

6. PEOPLE WILL THINK POORLY OF ME
Bull Crap!!! Everyone expects new/inexperienced CW ops to be somewhat tentative, make some mistakes and miss some copy. They expect it because THEY PERFORMED THE SAME WAY WHEN THEY WERE NEW/INEXPERIENCED. Some well-meaning ops, in an attempt to sooth the nervous new op will say, "Aw, no one will notice your mistakes" Bull crap! Of course they notice them! They'd have to be idiots not to. BUT, no one cares about a your mistakes. This is a hobby,Е..a means of having fun. It WILL be fun if you stop agonizing over it. The amount of fun you have at CW is inversely proportional to the amount you worry about it.

7. I'LL DO IT WHEN I GET BETTER
That's fine if you like spending your time procrastinating. "He was gonna get on the air tomorrow" would make a unfortunate epitath. "He really enjoyed his ham radio hobby and his CW" is a much nicer one. I waited until I was over 60 to finally get started in Ham radio. I often think of how much fun I could have had over the years if I had just bitten the bullet and jumped in. Now, I'm trying to make up for lost time. But, we all know that's impossible.

8. I HAVE PROBLEMS WITH THIS OR THAT TYPE OF KEY.
OkЕ.use whatever you're good with, and develop your skills on the others at your own pace. Whatever you do, don't try to swage your fist into a type of key that frustrates you. Learning new skills, while not easy, should be fun. Measure your progress in small chunks. Don't set your goals too far ahead. You must be able to see progress. If speed improvement is your goal, measure it one word per minute at a time. Don't try to go from 5 wpm to 10 wpm. That's doubling your speed!. It would be like me trying to go from 35 wpm to 70 wpm. Never happen,Е..go from 5 to 6. Then to 7, and so onЕ.

Continuation of .... / Rebuttal to the following;

8 GOOD REASONS FOR NOT GETTING ON THE AIR

Here are my five reasons I can't get on the air. Not in any particular order;

1. I'm at work, repairing other people's radios.
2. My XYL is dragging me off to some family gathering or Church.
3. My spouse/child/parent is ill or injured and I have to run to the hospital to visit them.
4. I'm in the hospital and they won't let me run a longwire out the window.
5.I'm in a coma.
