KH6JRM's Amateur Radio Blog

Things are quiet at the KKBG-FM/KHLO-AM news
room on this Memorial Day.  I just finished an exciting
2 days at the Hilo Drag Strip where the Big Island Auto
Club celebrated the 40th edition of the Memorial Day
Drags.  The station has broadcast coverage of the drag
racing season for 27 years and that falls under my job
description.  Extensive use of the FRS (family radio
service) and MURS (multi use radio service) is used
at the track to maintain contact with the tower, pit
areas, drivers, security, and track crew.  Low power
UHF FRS radios (0.5 watt TPO) and VHF MURS
radios (2 watts TPO) give those of us in the tower
a good 1.5 to 2.0 mile range.  The track also has a
legal, 100mw AM station for the fans, who can tune
in on the tower chatter at 1610 kHz. The 8' whip is on
top of the tower and gives a decent signal out to
a mile.  My reports are cell-phoned to the station
(4 miles away) for broadcast.  Racing fans may want to
get a good hand-held scanner and follow the action.
This isn't ham radio, but it does give us some radio
"face" time unitl we can fire up the rig at home.  Have
a good weekend.  Aloha, 73, 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
