There's One Line I Don't Mind Waiting In. "THE GRAY-LINE or GREY-LINE"

Image
  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 QRPp Fishing Lure Helped Me Snatch A BIG ONE Working My Greyline

Image
  Renowned Golfer Jack Nicklaus made this quote about fishing.  "There are always places to go fishing. For any fisherman there's always a new place, a new horizon".   I equate that quote to my portable Amateur Radio activities. There are always places to go operate Ham Radio.  There are always NEW Parks on the Air, Summits on the Air, Islands on the Air and other places to operate portable and another day or opportunity to make a QSO. During my daily Early Bird Parks on the Air activation on August 13, 2025, I decided to operate QRPp ( less than 1 Watt ) with my QRP Labs QCX 40 Meter Mini with a 9 Volt / 200 mAH battery.  Due to the excessive heat in the Ohio River Valley in Kentucky, U.S.;  I try to get out around dawn to "Beat the Heat" and recently take advantage of the morning greyline over my QTH. I don't operate QRPp often but I looked back at my previous QRPp operating and found I seem to do this when HF band conditions are questionable.  ...

These 2 Go Together Like Peanut Butter & Jelly. The QRPGuys Mini Tuner & YouKits HB-1B CW Transceiver

Image
   In May 2023, I purchased a 40 - 15 meter Mini Tuner Kit from QRPGuys. I didn't get around to assembling it until July 2023 which was likely not the right time for me to be building things.  For me, the summer months are the height of my bicycling and portable ham radio activities. It was an easy simple build less than an hour assembly.  The chart below show the amount of wire needed for 40 - 15 meter.       I had over 500' of 26 AWG wire so that was not an issue. I cut 100' of wire and started the process of building and marking the wire per each band and for the counterpoise.  I cut 72' for the total length to fold back for each band and a 28' counterpoise.  I found this approach very tedious and cumbersome. I spent the better part of two days while doing POTA activations trying to construct a wire to my satisfaction. At the time I found it was taking too much time away from my operating fun and put it all away. Fast forward to May 2...
