Many people are discussing the hobby Hamradio.
Is the technic and interest old. Is the internet the next generation for our youngster.
In some way the internet is faster. But is it better then Hamradio.

What if we have a manjor power failure what will work? Internet or Hamradio.

– How do people communicate true there cellphone without any power?
– Will the frige still work?
– Can we watch Television

The answer is simple. NO!! There is only one way to communicate true air HAMRADIO!!!
And if you think the hobby is old and Youngster are not interested you are wrong.

I just saw a very nice movie about a Boafeng UV-5R that is connected with APRS.
The technic these days is just getting better and better. And this at a low price for just $30 dollar.  In the EU it’s about 40 45 euro.

Video not available

As i considering to buy a DMR radio there is more and more coming on the market.
Hytera and Motorola where the very first with Tier-2 DMR equipment. As from januari 2014 also Kenwood started to sell there DMR line.

Prices are not that high as from the very first that D-star was coming alive. Over 600 , 700 euro for  just a mobile radio. and that with a option for D-star.

I think that was because only Icom developed a radio particular for D-star. Yaesu later on started to build D-star but complete with there own network. Well do ya hear any of it. It’s quiet ever sinds.
Hytera mobile radio starts at price for just over 300 euro. But if ya like to have the crown in Hytera then the X1p is a very nice handheld radio.

Motorola stands for well made equipment. And that also gonna cost a few extra bugs.

Register: You need to register otherwise you can not use DMR you can do that on the following link : http://www.dmr-marc.net/request_subscriberID.html

DMR in the Netherlands is not crowed . But more and more users are finding there way to buy a DMR radio.

If you like to see a nice video of DMR PA2JM made one.  www.youtube.com/watch?v=CI-vV-FZiUQ

Shops in the Netherlands that sells DMR equipement.

And some interesting links are:

i’m still deciding what do to. But soon i will be on the air with DMR.

Car_Accident ( just for illustration )

By Charlotte Burrous

 

burrousc@canoncitydailyrecord.com

Posted:   12/22/2013 08:22:48 PM MST

On a cold, bitter night earlier this month, the actions of a Good Samaritan and a ham radio probably saved the lives of a family.

“Amateur Radio (ham radio) is a popular hobby and service in which licensed Amateur Radio operators (hams) operate communications equipment,” ham operator Amanda Alden said. “There are about 750,000 licensed operators in the U.S.”

It began at about 7 p.m. Dec. 6 when Cody Fowler and his wife, Tina, and their two sons, Jacob and Timmy, were on their way home from Pueblo.

“They were on their last leg of their journey, about four to six miles south of (U.S.) 50 on Copper Gulch Road, when Cody noticed the vehicle behind them was no longer (in sight),”  said Alden in a press release.

Because of the bitter cold temperatures and the icy roads, Cody turned around and drove back down the road, where he discovered that a red SUV had slid off into a ditch. The five people in the car had climbed back onto the road.

“Cody could tell there were possibly serious injuries,” Alden said.

But no one in the car had a cell phone because the Fowler family had just purchased new ones in Pueblo. None of them were charged or activated and they could not call 911. At that point, Cody grabbed his son’s ham radio and got through to others on the line, telling them he had ran across an accident and needed someone to call 911.

That’s when Alden stepped in. Known with the sign call K1DDN, she notified  dispatch. With her cell phone in one hand and the ham radio in the other, she kept in touch with both sides to alert them of what was going on.

“Cody said when he got there, it was about 1 below. When he left, it was 10 below (zero),” Alden said. “He was in his shrubs from work in Pueblo. He put on the blizzard suit to stay warm, but he didn’t have any gloves so he was kind of suffering to stay warm.”

In  the Fowler vehicle, there was only one spot available for the family in the wrecked vehicle, so they took turns sitting in the Fowler vehicle to get warm. The family consisted of three teenagers, an adult male and an adult female.

During the course of the evening, two vehicles stopped to help, then 40 minutes later, Colorado State Patrol arrived on scene, followed by Deer Mountain Fire & Rescue and Fremont County Sheriff, Alden said.

It could have been another 30 minutes before someone might have arrived on scene.

“The victims would have had to endure extreme temperatures waiting for emergency services to arrive,” Cody said in the release.

Two of the family members were taken to the hospital and the Fowlers took one of them home.

With all the modern technology available in the world today, things might have turned out differently if the Fowlers had not owned a ham radio.

Although people try to compare to CBs, it’s more technical than that, she said. The operators have to take tests and are issued  a call sign by the Federal Communications Commission to operate on radio frequencies known as  “Amateur Bands.” The bands are reserved by FCC for use by ham radio operations,  said Alden, who  has helped with other emergencies, including the Waldo Canyon fire and Royal Gorge fire.

“But (I’ve) never (been involved)  in a critical time frame such as a car accident,” she said.

782207-Car0038The morning i had a small discussing with a collegue Ham om the Repeater Hilversum.

We did discuss about he problems i have with neighbours about my antenne system.

He told me that it was a bit my own fault with pictures and information on my website. Also the pictures of amplifiers that i put on the web where wrong.
So in that case it means that you not allowed anymore to provide information about equipment on your personal website.

Well that’s why i’m writing now this article. I find it strange. I think is the problem that people doesn’t understand or don’t have the knowledge how things are working.

On the equipment market there is not one Amplifier that hold exactly the 400 Watt what it legal to use in the Netherlands.
Why would ya say?

In many other countries its allowed to use a lot more then 400 Watts. For instance in the USA its allowed to use 1500 Watt or even more for experiments. So to provide a wide angle of people companies are making amplifiers that cover the need of lot of hams.

In that way they can build cheaper and faster in the same time. Otherwise amplifiers will be custom made. And the payment will cost ya a fortune.

** NOTE **
THE MAX limit of power is always 400Watt in the Netherlands.

There is no amplifier that hold 400Watt max. You have to build it yourself. Even then filtering will be worse to drive it to the max.
Is just as driving a car to the limit. It will collapse after a while. So you need a bit overkill to save your equipment.

Not all Pictures on my website are taken by myself .!! I’m not responsible if anything is read in a wrong way. This i will put from now on below any new article.

Team PJ2T CQWWSSB 2013For the resent CQWWSSB contest 2013 i made a trip to PJ2T.  Together with my collegue ( co-worker) Robert PD2UTA and Ton PA1CC we will participate in the contest.

I told Kelly ( N0VD) a long time ago that it would be great someday to be one of the operators of PJ2T. After a while he did ask me in the very early months of 2013. If i would like to participate and never doubt a moment. Later on Ton PA1CC also joined the team and was enthousiast to made the trip. My collegue Robert also joined the team but not as a operator. He wanted to visit curacao as a tourist. Later on Kelly asked him if he would like to be our chef during our stay.

Before the contest i made several qso’s to see what the condition where at that time.
A few flares where spotted just before the contest. Hope that will work out and wont dry out the band.

We did discover lower propagation as of the days before. But had to deal with it. If we have it all the others does.
After the contest we had a big celebration.  A new station record was set. There has never been this score over the past years. Over 40 miljoen point in 48 hours.

 

Contest location

 

The team we had was excellent and really like a family. I made a lot new friends during my stay in Curacao.
A small video will give you a good sample of the station and the weather conditions on Curacao. Till the next time on any contest location.

Radio amateurs in the United Kingdom have set a new 76 GHz distance record of 102 kilometers (approximately 63.24 miles). The September 14 contact between the team of Chris Towns, G8BKE, and John Hazell, G8ACE, at Batcombe Hill, Dorset (IO80rt59) and Ian Lamb, GW8KQW, in Eglwysilan Mountain, Gwent (IO81io36). This is also believed to be the first 76 GHz contact between England and Wales.

The participating hams used full-duplex narrow-band FM between GW8KQW and G8ACE and one-way FM between G8BKE and G8KQW. Signals on 76GHz were exchanged for more than two hours with a very gradual increase in average signal strength after some initial fading. The participants said it has been very difficult to improve on the previous record distances primarily due to the curvature of Earth; if the path is not line of sight, then it won’t work.

Towns jointly held the original UK distance record on 76 GHz of 79 kilometers (approximately 49 miles) for 11 years. A new world distance record on E band of 252.49 kilometers (approximately 156 miles) was set earlier this summer in the US by Robert Johnson, KF6KVG (CM97di), and Goran Popovic, AD6IW (DM06ms), in Kings Canyon National Park.

‘ Breakie breakie here 27 mc -er …. ‘ . That is the image that many people have of the radio amateur . A trucker who chats with colleagues or someone with a self together pieced  radio device is connecting with people on the other side of the world . But then we put the amateurs in a bad light . There are no less than 13,000 registered at Radiocommunications Agency , including astronaut Andre Kuipers . Many radio amateurs , with their pioneering spirit for important innovations what they are taken . Later used by the commercial market.

 

The Agency shall inform the mandatory exams for radio amateur , ensures that radio frequencies are issued , register the call sign of the radio amateur , makes the rules and ensure compliance with those rules . One of the people that goes with the Telecom Agency is , George Petersen , Safety consultant .

george_petersen

extraterrestrial contact

According to Petersen , the group of radio amateurs varies pioneering builders ( the smallest group ) or enthusiasts people who want to score radio contacts far away. “There are every weekend contest to see what you can do . Transmitting for example in Morse code  is very popular worldwide, hundreds of thousands people  are participating in this. ” The group is aging well, says Petersen , and is reducing because of Internet capabilities as for example Skype . “But the challenge of the homebuilder is the magic of making contact with the other side of the world , by air will always be there . ” And sometimes there is even extraterrestrial contact : On his last journey astronaut André Kuipers made into space contact on amateur frequency  with radio amateurs , and he also talked to students through that frequency . Petersen : ” The was the case to follow the ISS station with your antenna and then you had a shedule for over ten minutes to make a contact .”

Petersen: ” the magic of making contact with the other side of the world by air will always remain ”

Economic value

The amateur radio are also broadcast in the commercially very interesting bands from 100 to 5000 MHz . There is increasing pressure on those bands because especially the mobile operators demand more and more space . “I can imagine that the coming years will be critical for the space available to use with amateurradio , but at the same time there are also more and more obsolete at low frequencies for the amateurs . And do not forget. economic value. As in the Netherlands ten or a hundred amateur pioneering the frontiers of technology , then you talk about economic interest. Think of the developments of Software Defined Radio , a new radio technology . ‘

survey

The amateur radio gave Radiocommunications Agency recently a 6.9 for service , as a survey showed . However, they find that the agency should check for social misconduct on amateur frequencies . Additional According to Petersen , the Agency may impose fines for example, insulting or threatening , you should report it to the police . “But if a radio amateur is busy willfully disrupt the transmissions of other
amateur radio or at a frequency broadcasting which, for example traffic communicates , then the agency has sufficient enforcement resources to sanction , including fines and give the amateur a forbidden sign to operate.
