Activating NPOTA from the Sleeping Dunes National Lakeshore

What’s the saying about being busier than a one-armed paper hanger? Whatever it is, the phrase kept coming to me New Year’s Day as, in 26 degree weather made even colder by a stiff westerly wind off Lake Michigan, I was trying to sting up an antenna outside my Roadtrek CS Adventurous XL motorhome at the Sleeping Bear Dunes National Lakeshore.

I was essentially one-handed.

Still recovering from my Dec. 2 total shoulder replacement, I had just been cleared by the doctor to drive, but was left with strict instructions to go easy – very easy – on the right arm and shoulder.

I was participating in what will be a one year amateur radio event called National Parks On The Air commemorating the Centennial year for the National Parks Service. The goal is for ham radio operators to use portable radio gear in NPS sites to make as many two-way radio contacts with other amateurs around the world, this promoting National Parks and showcasing the amateur radio hobby.

I opted to make the 250 mile trip from my Michigan home to the Sleeping Bear Dunes National Lakeshore,  made up of 64 miles of beaches along Lake Michigan, two islands, 26 inland lakes, more than 50,000 acres of land, and the monumental 450-foot sand dunes from which it gets its name.

Jennifer and I have been there many times over the years, but all of them in the summer and fall.

This was our first winter visit and I wanted to activate the location on January 1, joining some 85 other amateurs who were doing similar things across the country at other NPS properties on the first day of the year. Thousands more hams scoured the airwaves looking for our signals, making contacts that qualify in various awards based on how many NPOTA stations one makes two-way exchanges with.

But before I could even turn on my radio, I had to set up an antenna system. With one arm. In the cold.

I bought the antenna system from Spiderbeam, a company that specializes in portable and lightweight amateur antennas. It consists of a fiber glass pole that telescopes up, section by section, to 40 feet high. I found a post on the edge of the parking lot that I could secure the pole to and, mostly using my left hand to lift and my right hand to screw tight the telescoping sections as they rose up, I was able to get the pole to its full height with no problems.

Then it came time to sting out the Aerial-41 Model 404-UL antenna,  made up of insulated  multi‐strand  copper‐clad  steel  wire that has 1mm outer diameter,  very low wind load  and weighs only one ounce,  yet it still maintains a breaking strength of 22 lbs. There were two lengths of the ultra thin wire I had to unwind, securing them in an inverted Vee shape. The first went just fine. I tied it off and started on the second. Then I had problems. The wind caught it just right and, suddenly, it was tangled. I had to untangle it pretty much with one hand. One gloveless hand, since gloves made it too cumbersome to straighten the wire.   The special lightweight coax used has lower loss than typical RG‐174U, yet weighs only 185gr

Eventually, I straightened and unkinked the wire on the second leg and secured it, too.

Then it was time to unwind the coax. It, too is very thin.The special lightweight coax used has lower loss than typical RG‐174U, yet weighs only 6.5 ounces. Alas, as I started to uncoil it, the coaxial cable feedline tangled. It was a really stiff wind. Cold, too.

Same process. Lots of muttering from me. Jennifer, inside the warm RV, once said “Everything okay?” I muttered an answer it was good she didn’t hear.

But the coax was only 40 feet long. Slowly,  it unraveled and I was able to feed it inside the Roadtrek, where I connected it to my Elecraft KX3  transceiver, which in turn was powered from a direct connection to my Roadtrek’s 12 volt battery system. I plugged in the computer I  use to control parts of the radio, loaded my Maclogger DX logging program and I was in business, once I stopped shivering.

The heater inside the Roadtrek made a very comfortable 72 degrees. Jennifer made me a cup of hot chocolate as I started making contacts.

In two hours, I worked 117 stations in 33 states, three Canadian provinces and Puerto Rico. I had a ball.

I parked  at what is known as the Dune Climb area. The Dune Climb is the main attraction for the kids who love to run and roll down the dunes in the summer. Located just about 5 miles north of Empire on M-109, you can see it on the west side of the road. Visitors love to bring their children and friends to the Dune Climb because they remember how much fun they had playing in the dunes when they were here as children. Jennifer and I had climbed in many times with our kids and grandkids over many summers.

But in the winter, it is equally as popular. For sledding.

Dozens of kids, bundled up like Pillsbury doughboys and carrying all manners of sleds and toboggans and snowboards, made the long trip up the snow covered slopes, stopping often to rest. The trip down was much faster. Many tumbled down after losing their sleds on the steep decline, their laughter and squeals carried on the wind to the parking lot below.

I played ham radio for a little over two hours. Taking the antenna system down was much simpler, with no tangles.

It was a good shakedown trip for me after the surgery and a welcome break from the cabin fever that plagued me during the month of recuperation following the surgery. It was also great preparation for our upcoming winter campout at the Tahquamenon Falls State Park in Michigan’s Upper Peninsula on Jan. 23.

Think I’ll bring along the radio gear for that event, too. The North Country Scenic Trail is a multistate hiking trail administered by the NPS and it runs right through Tahquamenon Falls, making it another place I can activate for National Parks on The Air.
