Horse-Shoe Trail Bike Ride

I headed out this morning with the dual purposes of getting in a bike ride and doing a little portable QRP operating.  My destination was a 3-mile section of the historic Horse-Shoe Trail that runs through Warwick County Park.

I had never been on this section of the trail before, so I didn’t know exactly what to expect.  It’s a beautiful trail and very well maintained.  The stone and sometimes rocky surface was better suited for a mountain bike.  My old hybrid bike was able to handle it with no problems, though.  At the bottom of a rocky hill, I came across an open field and decided to set up the radio there.

I set up an experimental antenna that uses a compact 20-foot telescopic pole I picked up recently on eBay.  It’s basically a variation of the Rybakov Vertical with a 25-foot wire fed through a 4:1 unun.  I laid out one 25-foot radial on the ground.  I mounted the pole by simply placing it over a screwdriver shoved into the ground.  Since the wire is longer than the pole, I attached the unun to the bike’s handlebar and ran a short coax down to my KX3.  The KX3’s ATU matched it easily from 40 through 10 meters.

I called CQ on 20 meters and had a nice chat with Lynn, NG9D, near Chicago.  I think he thought I was crazy using an untested antenna out on a trail.  (I had a backup!)

Moving down to 30 meters, I worked Mike, W9KY, in Indianapolis.  I finished up on 40 meters with a short 2-way QRP QSO with Jack, WD4E, in North Carolina and a nice QSO with NY2MC aboard the USS Ticonderoga in Whitehall, NY.  I did a little more experimenting with the antenna before packing up the bike for the ride back.

As I expected, this antenna isn’t a real barn burner on 40 meters but it seems to work well enough for casual operating.  The pole weighs about 12 ounces and collapses down to about 26 inches, making it easy to transport via bike or backpack.   I definitely need to make some refinements to the antenna, though.  If it works out, it will be the subject of a future post.

It was a nice morning in a beautiful park.  I’m looking forward to exploring some of the other trails.
