KH6JRM's Amateur Radio Blog

I can't believe how fast the Christmas holiday is
coming.  Wasn't Thanksgiving just a few weeks
ago?  Time seems to quicken with advancing age.
As a child, it seemed forever until the holiday
season arrived.  Anyway, the season is keeping
the newsroom busy--and that's a good thing.  At
least I still have a job.  I wish I had it in my power
to get those unemployed back to work.  Meanwhile,
I'll be able to sandwich in some needed antenna work
before the weekend. I will be restringing the vertical
this Saturday, since the combination of salt air, rain,
and insect damage is destroying the #14 gauge wire
attached to the 33' fiberglass mast.  The insulation is
slowly degenerating under the tropical sun.  This project
has been on the back burner for a few weeks.  Follow-
ing the maintenance, I'll work a few hours on the Swan
100-MXA--mostly cleaning pots and blowing the dust
off the case.  The circuit boards appear in good shape,
so everything should be up to speed by Saturday evening.
Most likely, I'll just make a few casual contacts and relax
a bit with the J-38 key on the lower 25kHz of 40 meters.
Have a good weekend, protect yourself on the highway,
and have some egg-nog for those of us in Hawaii.  Aloha,
73 de KH6JRM.

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

If you can't see the video, please insert this title URL into your browser search box: Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas. The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lack
