Homebrew vertical dipole

I’ve been looking around for good ideas for a portable HF antenna and finally settled on Robert Johns’ (W3JIP) plan from a QST article (Aug 88). The antenna design is a vertical dipole (6M to 40M), using a loading coil at the base of the vertical with a tap and the other half the dipole is formed with a 1/2 wave length cut of wire. The coil is mounted on a 3/4″ PVC pipe which slips into a 6″ length of aluminum tubing. The tubing then slides into a bracket designed to hold a flag. Mounted on the bracket is a SO-239 with the center pin making contact with the bracket. The main element sitting on top of the coil is 8′, but you can lengthen it to 11′.

I spent the morning gathering the parts, had a hard time with some of the specific items, but ended up with a couple work-arounds. I put the coil together first, that went pretty easy. W3JIP’s plan calls for #8 aluminum ground wire for the coil – which no one has. I used copper instead. I wrapped the copper around a 4″ piece of PVC. The directions call for 12 turns, but I only purchased 12′ of copper (the directions didn’t say what length to get)… ended up getting 9 turns. I mounted the coil to the PVC and then secured the trailing end up the coil to a piece of aluminum tubing inserted inside the PVC. The element gets mounted above the coil and I secure the tap at the base of the element.

Once I had everything together, I went outside and mounted the coil section to the top of a tripod, inserted the 8′ aluminum element above the coil, set the tap at the top of the coil, ran a length of wire out as the other half of the dipole, ran some RG-58 out from my Icom 706 and after playing with the tap a bit was able to get out to Texas on 20M.

I have some more work to do:
– better secure the SO-239’s center pin to the bracket and bottom of the coil
– attach a banana plug to the ground side of the SO-239 to allow quick changes for switching bands
– find a way to secure the base of the antenna to a painter’s pole

I know the antenna will work on 20M, now I would just like to get it working on 40M.

Lighthouse activation

On Sunday I headed out to Fort Monroe and activated the Old Point Comfort Lighthouse with limited success. About 4 hours on the air and two contacts. The first contact was Colorado, a loud, booming 59. The next was Virginia Beach…. about 5 miles across the water. I need to come up with a better plan than my hamstick vertical. I’d like to do the next activation during Amateur Radio Military Appreciation Day coming up on Memorial Day weekend.

Anyone have any antenna ideas?

World Amateur Radio Day 2006 certificate

World Amateur Radio Day, Tuesday, April 18, commemorates the founding of the International Amateur Radio Union (IARU) in Paris in 1925. The 2006 theme is “Amateur Radio: A gateway to information and communications technologies (ICT) for today’s youth.” With support from PZK, the Polish Amateur Radio Union, MK QTC, the Polish radio amateurs’ journal again will sponsor the World Amateur Radio Day (WARD) certificate. To qualify, stations must complete 10 HF contacts or 5 VHF contacts on April 18 between 0000 and 2400 UTC. To obtain the full-color certificate, send a log extract including the list of QSOs and $6 US (€5) to: The Radio Amateurs’ Journal MK QTC, Suchacz-Zamek – Wielmozy 5b, 82-340 Tolkmicko, Poland, on or before May 31, 2006. The World Amateur Radio Day certificate also is available to SWLs who log the same numbers of reports.

Digital Modes Samples

Click on a digital mode to hear a brief (most <100 kilobytes) sample of the sound these modes make. Hopefully this link will help you identify a mode you've heard (or help me identify ones I've heard!). Many folks have submitted excellent quality, lengthy files which are no trouble for me to accept, but I do generally drop the sampling rate and length to make them more reasonable to download over a dial-up line. The intent here is more for recognition by ear than for signal analysis. I have higher quality samples of some files, please email me to request them (up to 3MB). http://kb9ukd.com/digital/

Shore thing Virginia Beach lighthouse is a beacon of history

By KRISTIN DAVIS

Old Cape Henry Lighthouse should have disappeared when its lantern went black more than a century ago.

Cracks split through its stone face and inspectors deemed it unsafe. A newer, more modern one beamed a few hundred feet away, safely beckoning ships into the Chesapeake Bay.

But from the time Old Cape Henry went up in 1791 until its replacement was lit in 1881, the lighthouse was more than a guide. It was a landmark, a symbol of a young country’s progress.

So Old Cape Henry stayed.

That’s a lucky turn of history for me and dozens of others who climb its winding staircase on this warm March day. And lucky for the thousands of others who’ve followed in the keepers’ footsteps over the years.

This is my second visit to Old Cape Henry, one of a dozen lighthouses I’ve visited in Florida, Virginia and North Carolina. I do not collect miniatures or wallpaper my house in the bricked, painted and patterned towers, but they do intrigue me.

Lighthouses represent another age, when sailors relied on stars and simple instruments and beams of artificial light to guide them. They represent a time when a man or woman spent years by the lonely sea, climbing hundreds of steps in heat and cold and storms.

Today Old Cape Henry Lighthouse is just two miles from Virginia Beach’s hub, but getting there isn’t easy. Because it sits on Fort Story military base, visitors must first pass through security. This could involve a car search.

Once you are on the other side, away from the glittery allure of shops, restaurants and million-dollar beach houses shoehorned along the shore, you’ll find a largely unspoiled landscape–much like it was when light keepers lit Old Cape Henry’s oil lamps.

U.S. history here is nearly as old as it gets. The first permanent European settlers landed at Cape Henry in 1606, made their way up the James River and founded Jamestown.

Old Cape Henry lighthouse overlooks the place they first stepped ashore. Old Cape Henry came along 185 years later, after Virginia had gone from colony to state.

By then the beacon was long overdue. For half a century the Colonial governments of Maryland and Virginia got tangled in “red tape” over its construction. When the materials were finally bought and delivered, the Revolutionary War intervened.

The lighthouse was among the first orders of business when the very first Congress of the United States met in 1789. It was also the first federal work project.

Cape Henry Lighthouse took about a year to build and cost $17,700. (“Old” was added when the new one opened in 1881.)

The slim, octagonal tower was made with stone from our very own Aquia quarries in Stafford County–the same sandstone used in Mount Vernon, the White House and U.S. Capitol. You can also find it at Kenmore, home of George Washington’s sister Betty Lewis and her husband, Fielding Lewis, in Fredericksburg.

Workers had quite a time hauling the heavy, awkward sandstone all the way to the coast by way of the Rappahannock River.

Today the 90-foot lighthouse stands as tall and imposing as it must have in its early days, though I imagine salty winds and rain have faded it.

The light that warned ships is more than 100 years gone, but visitors can stand inside its lantern and see where oil lamps–and later, reflecting Argand lamps–once glowed.

It costs $4 to climb Old Cape Henry. A friendly staff sells tickets inside a quaint gift shop where lighthouse coins, books, coasters and shirts line shelves.

The shop’s back door leads outside, where Old Cape Henry stands at the top of a steep set of stone steps.

It is early March, but the weather feels more like midspring. The sky is soft blue, and warm breezes blow in from the bay.

Old Cape Henry is dim and cool, retaining its winter chill thanks to the stone exterior and brick lining added a few years before the Civil War. The black iron staircase spirals up like neatly positioned dominoes.

The view from the bottom is dizzying. I climb anyway, counting the steps as I go.

The original stairs were wooden–and flammable. They remained for 60 years without incident and were replaced during a renovation.

When I reach the platform where a vertical ladder leads to the lantern, I’ve counted 85 steps. But I can’t be sure because three little windows have distracted me along the way.

It is warm and bright inside Old Cape Henry’s small glass crown. I take in the unobstructed, 360-degree view.

This would have been a good day to be a lighthouse keeper, standing as high as the birds over a sparkling blue bay.

Next Solar Cycle to be Later but More Intense, New Research Suggests

NEWINGTON, CT, Mar 7, 2006–The next solar cycle, Cycle 24, will be a year or so late in arriving but will be far more intense than the current cycle now winding down–perhaps as much as 50 percent stronger. That’s according to a new computer model unveiled March 6 by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. The researchers developed the first “solar climate” forecast using a combination of groundbreaking observations of the sun’s interior from space and computer simulation. Key to predicting the solar activity cycle is an understanding of plasma flows in the sun’s interior.

“We understood these flows in a general way, but the details were unclear, so we could not use them to make predictions before,” said NCAR’s Mausumi Dikpati, who published a paper on her research March 3 in the online edition of Geophysical Review Letters. Magnetic fields are “frozen” into the solar plasma, so plasma currents within the sun transport, concentrate and help dissipate solar magnetic fields, Dikpati explained. She said the new application utilizes innovations in direct study of the sun’s interior as well as historical data on which previous forecasts have depended.

The new technique of “helioseismology” allows researchers to see inside the sun. Helioseismology traces sound waves reverberating inside the sun to build up a picture of the interior, similar to the way ultrasound technology can create a picture of an unborn baby. The new model, known as the Predictive Flux-transport Dynamo Model, has simulated the strength of the past eight solar cycles extending back to the early 1900s with 98 percent accuracy.

If proved correct the forecast offers a sort of bad news/good news scenario for Amateur Radio operators, but not all solar scientists agree with the newest prediction. NASA solar physicist David Hathaway has declared that Cycle 23’s solar minimum already has arrived. Nonetheless, Hathaway, who was not involved in the Dikpati study, says he is excited about the new model.

“It’s based on sound physical principals, and it finally answers the 150-year-old question of what causes the 11-year sunspot cycle,” Hathaway said.

Hathaway says his own research concurs that Cycle 24 will be more intense than Cycle 23. However, he predicts the next solar cycle will begin late this year or early next year rather than a year later. He points out that historical data suggest that the more powerful cycles begin earlier rather than later.

Under the model developed by Dikpati and her colleagues, the poor HF propagation of Cycle 23’s terminal stages won’t reverse course until late 2007 or early 2008, and Cycle 24 won’t peak until 2012. But higher intensity normally means more and longer HF band openings–with the exception of solar storms. As the sunspot cycle bottoms out, however, conditions can be more favorable for VHF and UHF operation.

For public utilities and satellite operators, the new model’s prediction regarding solar storms is mostly bad news. Depending on their intensity, solar eruptions–with their powerful releases of radiation–can disrupt power grids on Earth and satellite operations in space, including communications links and GPS. Previous forecasts for Cycle 24 had suggested a significantly milder intensity.

A next step for the NCAR researchers will be to develop an advanced model that can give advance warning of individual solar storms, says Richard Behnke of the National Science Foundation. NASA’s Living With a Star program and the National Science Foundation funded the research.–information from NASA, NCAR and news reports was used in developing this report

On the far side of the world

Summer in Antarctica means temperatures in the mid-20s to the mid-30s with fog, snow drifts and winds reaching 65 mph or more. Hardly an ideal vacation destination, but for Dr. Gary Stouder it’s where he wanted to spend his winter.

“I want to do this because this is the biggest adventure of my life,” he said in an e-mail interview. “I have always wanted to be in the Antarctic, and this was a great opportunity.”

Stouder is part of a group of 20 ham radio operators who have battled the frozen tundra in order to set up their radios and contact people all over the world from Peter 1 Island, Antarctica.

“There have only been about 50 humans to set foot on Peter 1 Island,” he said, noting that the area is less traveled than outer space.

On Friday, the team broke camp and prepared to journey back home. During their time on the remote island, team members took 17,000 photographs and established radio contact with hundreds of ham operators around the world. They also set up a weather station and explored the rugged terrain.

The isolated location has an extinct volcano, icebergs and little wildlife. It is the most desolate place on the earth, but for a ham radio aficionado, it represents a unique opportunity to communicate with the rare site.

Because of its remoteness, the island counts as another country and for hams around the world, having confirmation of contact with Antarctica is akin to having Willy Wonka’s golden ticket.

“It’s kind of like a stamp collector getting a rare stamp,” Stouder said, noting that the group has made about 70,000 contacts so far.

According to Stouder’s wife, Joy, this isn’t the first time Stouder has tried to reach Antarctica. Last year, he traveled as far as the southern tip of Argentina before weather and travel complications canceled the trip. He didn’t think he would get the chance to go, but then after seeing “The March of the Penguins,” she said he got fired up about the trip again.

“I was a little bit scared at first, but I think it is important to let him seek his adventure,” she said.

Stouder has dual roles on the mission. Not only is he one of the hams transmitting from the island, he also serves as the group’s medical officer. His medical equipment includes a defibrillator and IV fluid. He said that the group is eight days away from the nearest medical care.

“This is a great challenge for me to be ready to do this even though I hope everyone stays well,” he said. “I also really like being able to make contacts with people throughout the world.”

Stouder became interested in radios when he was 10 years old, listening to the short wave and dreaming of faraway places. He said he got his first ham license when he was 17. Over the years, he has talked to almost every country in the world, not to mention places out of this world.

“We’ve talked to the astronauts on the International Space Station with school groups,” Joy Stouder said.

Stouder said that he doesn’t have another adventure on tap after this. He works part-time with the Hancock Health Network, but both he and his wife enjoy traveling to exotic locales such as Australia, China and Japan. He is scheduled to return March 6.

“We both have an adventurous spirit,” Joy said. “But I hope this trip (to Antarctica) will fill that void for a while.”
