Ham Happenings: CK6S for Calgary Stampede July 5 to July 15

Read by: NICKI KF4DHK

The Calgary Amateur Radio Association will be operating special event station CK6S from July 5 to 15th. This to celebrate the 100th Anniversary of the Calgary Stampede. The Calgary Stampede is an annual rodeo, exhibition and festival held every July in Calgary, Alberta, Canada. The event’s roots are traced to 1886 when the Calgary and District Agricultural Society held its first fair. In 1912, American promoter Guy Weadick organized his first rodeo and festival, known as the Stampede. He returned to Calgary in 1919 to organize the Victory Stampede in honor of soldiers returning from World War I. Weadick’s festival became an annual event in 1923 when it merged with the Calgary Industrial Exhibition to create the Calgary Exhibition and Stampede. The ham radio special event station CK6S plans to use frequencies in the general portion of the United States phone bands. These will be around 3.825, 7.180, 14.250, 21.320 and 28.475 MHz. A special QSL card will be available through the QSL bureau or direct by following the CK6S/VE6AO QSL instructions at QRZ.com.

Emerging Technology: New Data Transfer Method Promises Up to 2.5 Terabits per Second

Read by: RANDY KJ4TFU

American and Israeli scientists have developed a new technology of wirelessly transmitting data using twisted beams of light that could produce a theoretical throughput of 2.5 terabits per second. Amateur Radio Newsline’s Heather Butera-Howell, KB3TZD, has the story of the science making this possible: The new method of high speed data transfer reportedly uses orbital angular momentum or O-A-M to increase the amount of information that can be carried by a single stream. To accomplish this feat, the researchers twisted together eight 300 Gigabytes per second visible light data streams using O-A-M technology over a space of one meter to achieve speeds of 2.5 terabits per second. The development comes just one month after it was finally proved that orbital angular momentum is actually possible.

Using this new orbital angular momentum technology an infinite number of conventional transmission protocols such as WiFi and LTE, can be twisted together for faster speeds without the need for more spectrum. For perspective, that’s more than 8,000 times faster than the fastest home Internet connection at 300 Megabytes per second. The development team says that it will be working increasing the transmission distance which currently at only 1 meter. The theoretical distance limit for this new method is likely to be less than one kilometer. At least in the foreseeable future.For the Amateur Radio Newsline, I’m Heater Butera-Howell, KB3TZD, in Berwick, Pennsylvania You can read more on-line at tinyurl.com/super-speed-data.

Surplus B-17: Way Back When the Average Man Had Guts…or Was Crazy

Read by: MARTHA KJ4RIQ

Shortly after WWII a guy named Art Lacey went to Kansas to buy a surplus B-17. His idea was to fly it back to Oregon, jack it up in the air and make a gas station out of it. He paid $15,000 for it. He asked which one was his and they said take whichever you want because there were miles of them. He didn’t know how to fly a 4-engine airplane so he read the manual while he taxied around by himself. They said he couldn’t take off alone so he put a mannequin in the co-pilot’s seat and off he went.

He flew around a bit to get the feel of it and when he went to land he realized he needed a co-pilot to lower the landing gear. He crashed and totaled his plane and another on the ground. They wrote them both off as “wind damaged” and told him to pick out another. He talked a friend into being his co-pilot and off they went.

They flew to Palm Springs where Lacey wrote a hot check for gas. Then they headed for Oregon. They hit a snow storm and couldn’t find their way, so they went down below 1,000 feet and followed the railroad tracks. His partner sat in the nose section and would yell, “TUNNEL” when he saw one and Lacey would climb over the mountain.

They landed safely, he made good the hot check he wrote, and they started getting permits to move a B-17 on the state highway. The highway department repeatedly denied his permit and fought him tooth and nail for a long time, so late one Saturday night, he just moved it himself. He got a $10 ticket from the police for having too wide a load. (Armed Services Mutual Benefit Association, May 7, 2012)

3 Additives Your Car Doesn’t Need

By Tara Baukus Mello – Bankrate.com

Read by: Jerry KE4ETY

If you are like most Americans, your car is older and perhaps starting to show its age, so it’s natural to wonder if it doesn’t need a little extra something to give it more oomph.

While it is important to take care of your car and follow the manufacturer’s recommendations on maintenance, don’t be tempted by snazzy advertisements or the dealership that your car needs additives.

Here are three common additives you might be enticed to buy and why you don’t need them.

Gas additives

The claims are big — improving performance, reducing your emissions and improving your gas mileage — but the fact is, none of these additives are necessary if your car is properly maintained.

Those designed to reduce knocking may actually do so, but using them simply masks a problem. It doesn’t fix it. Engine knocking is a sign that your car needs a repair, so make a trip to your mechanic to rectify the problem instead. Tests on additives designed to clean your fuel system have not been shown to make any significant difference in reducing corrosion or deposits and don’t improve performance, while tests on additives that claim to improve gas mileage never have shown significant improvements, the Environmental Protection Agency says. The only gas additive that has proven useful is a stabilizer, but this should only be used in cars that aren’t driven very often.

Extended-life Radiator Coolants

Read by: GEORGE KC4TMV

The proper mix of radiator coolant and water is essential to keeping your engine cool in both hot and cold temperatures as well as to prevent corrosion. Some coolants are promoted as extended life, and they use a different type of corrosion inhibitor.

While the claims are valid, automakers designate their cars for one type or the other, so don’t assume extended life coolant is best for your car, and never mix the two types as that affects the corrosion inhibitors.

Check your owner’s manual to see which type is recommended. Follow the manufacturer’s schedule for draining and replacing the coolant as well. More frequent coolant flushes are a waste of money.

Oil Additives

Read by: ED KE4JWS

With an older, high-mileage car, it’s easy to believe the engine is getting tired and needs an additive to improve performance or reduce wear. But oil additives simply don’t work and may actually harm your engine, according to numerous independent testing agencies.

In fact, the Federal Trade Commission has gone after several companies that sell these additives for false advertising. The dreaded engine sludge that causes an engine to run poorly or even seize is a rare occurrence and typically happens only when oil changes have been neglected or if the car has been driven a lot with an extremely low oil level.
