Ham On A Bike

  Drive Thru Lines, School pick-up Lines, Bank Lines, Grocery Store Lines, Airport Lines and the lists of lines can seem almost endless.  Recently I've come to enjoy standing and waiting in what's called  "THE GRAY-LINE" or "GREY-LINE". Since I'm in the U.S., I'll use the Gray-Line spelling. What is "THE GRAY-LINE"?  For those new to Ham Radio or have not move that far along in their journey of the hobby; it can be defined this way.  "THE GRAY-LINE" is a band around the Earth which separates daylight from darkness.  Propagation along the gray line is very efficient.  The main reason is the D layer of the ionosphere, which absorbs HF signals, disappears rapidly on the sunset side of the gray line and it has not yet built upon the sunrise side.  In the YouTube below Dave Casler explains.  I've worked "The Gray-Line" on many occasions over the years but not in the last few years.  Here it is August 2025 and August is ty...

  This series started out with a less than a couple of handful of "Hams on a Bike". Word got around the world and I've been pleasantly introduced to more and more Amateur Radio operators who in one form or another use bicycling for their Parks on the Air, Summits on the Air, World Wide Flora & Fauna and portable operations.   Here are links to the first two parts of this series. I Am Not Alone! There Are Many Of Us. Part 1 I Am Not Alone! There Are Many Of Us. Part 2   Our hobby is SO GREAT that it has so many sub hobbies. I've come to know ham radio operators who hike with their rigs, kayak with their gear, fish with their gear, fly with their gear, ride in balloons with their gear and even jump out of a perfectly good airplanes with their gear and make QSOs while doing these other hobbies. By now I'm sure you have come to understand that, I Am Not Alone!  There Are Many Of Us. H ere is one of my favorite SOTA operators.  The Ham Ninja - N1CLC ...

  This is the second of my series, "I Am Not Alone! There Are Many Of Us" about Ham on a Bike.  Here is the link to the first installment. Ham on a Bike - I Am Not Alone! - There Are Many Of Us, Part 1 In this post about "Hams on a Bike", I'll introduce you to those who not only push the bounds of portable Ham Radio operations but cycling as well. If you follow my Parks on the Air activations and think what I do is out of the ordinary or extreme, it does not hold a candle to these operators.  Some of them I call extreme "Hams on a Bike" operators. I consider this person to be an extreme Ham on a Bike operator.  Dugbo - KD7DUG, better known as  "Left Coast Ham Radio"; regularly takes his QRP Labs QMX rig, which he built; for his Summits on the Air activations. Dugbo shows what it takes to do a Mountain Bike SOTA activation this time while chasing Adam - K6ARK. QRZ - KD7DUG   There is only one word for this Amateur Radio Operator who takes his ...

If you look at the above photo, it may depict a lonely road. That is far from the truth.    BEHOLD!  I Am Not Alone. There Are Many Of Us. Its just another day in how I've done my portable ham radio activities for years. For various reasons I became Car-Free more than 10 years ago.  Bicycle transportation is widely more prevalent in countries outside of the U.S. However, that doesn't negate some of the U.S. Amateur Radio operators who participate in Parks on the Air, Summit of the Air,  World Wide Flora Fauna activities and others who provide VHf/UHF Public Service communications from using cycling to enjoy portable ham radio activities. For those Amateur Radio operators  outside of the U.S.  who use cycling in their portable operating, it seems to be second nature.  I get replies to social media posts and comments about my Ham on a Bike activities. All the comments have been positive. A lot of inquisitive questions about rigs, antennas, keys, bat...
