It's only a matter of time before a X-Class solar flare or strong Coronal Mass Ejection hits Earth head on with devastating results to our power grids, communications, and our digitally managed economies.  If we're not prepared for the inevitable, we could wake up the next morning in the 19th century.

By early October 2016, NOAA should have a better idea of just how dangerous X-Class flares and CMEs are, thanks to a new method of predicting the intensity of solar geomagnetic storms.  Scientists have successfully integrated the data gained from sun-orbiting satellites into a new model that "spells out which power grids are at risk" from intense solar activity.  The new tool should give us some advanced warning of intense solar activity, so that sensitive medical, communications, and economic systems can be better protected.

This quest is urgent, considering the past effects of solar storms, beginning with the 1859 Carrington Event that destroyed telegraph stations to the 1989 solar flare that wiped out Canada's entire Hydro-Quebec grid for hours, leaving millions of people without power.  Solar flares have "friend" transformers in South Africa and overheated transformers at a Swedish nuclear power plant.

As radio amateurs, we should be aware that our solid state, digitally sophisticated equipment is equally susceptible to damage.  That's why I have an old tube rig standing by in case my more modern transceiver becomes an expensive door stop.  It might be advisable to build a Faraday Cage or other shielding device for your transceivers in the event we are warned of a super strong solar flare.  You may also want to consider alternate power sources should the flare destroy the electric grid.  The warning is out. The time to prepare is now.

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
