As a former broadcast news director and part-time broadcast engineer, I still remain fascinated by the communications wonder known as AM radio.  This article by the anonymous "Wandering Engineer"  struck a familiar chord and reinforced a wonderful memory.  According to this experienced radio engineer, not enough of us in the Amateur Radio Community talk about the "hyperband" and its standard medium wave broadcast cousin or the role ham radio plays in our profession.

The author believes it was the "romance" of AM radio many years ago that spurred our interest in becoming amateur radio operators and, eventually, broadcast engineers.  You can get a feel for what the standard broadcast band was like before IBOC (In-band-on-channel), digital modulation, and switching power supplies gradually supplanted tube-powered transmitters and brought in a new age of digital broadcasting by venturing into the expanded AM broadcast band between 1610 kHz and 1700 kHz.

You may have discovered this fairly new band by tuning below the 160 meter amateur radio band (1800 kHz to 2000 kHz) just before you "called it a night." One hundred sixty meter enthusiasts have done a remarkable job of restoring old AM, plate-modulated transmitters so they can work the "gentlemen's band" of 160 meters.  When 160 meters rolls into my home on Hawaii Island, it's a joy to listen to the outstanding quality some of my fellow hams have incorporated into these transmitting veterans.

If you can spare a few moments before you "throw the big switch,"  tune down into the "hyperband" of 1610 kHz to 1700 kHz and get ready for a real treat. Power limitations (10 kW day, 1 kW night), shortened antennas, and uncertain propagation make many of these AM stations a difficult catch, especially in Hawaii.  These stations remind me of my younger days, huddled over an old Hallicrafters S-38 or Hallicrafters SX-62A receiver trying to pull out the "tough ones" on the standard broadcast band (540 kHz to 1600 kHz).

Every once in a while, I fire up the old SX-62A and relive some of those memories by exploring the upper ends of the standard broadcast band and its younger siblings in the "hyperband" of 1610 kHz to 1700 kHz.  My early days as a MW and SWL fostered a keen interest in radio, something that helped me get an Amateur Radio license and a low-paying, but totally satisfying , job in the broadcast industry.  Even though I retired from active broadcasting, I still get a thrill out of working the "hard" ones.

Perhaps it was no surprise that I gravitated to amateur radio, since the engineers who maintained my stations were hams and encouraged me to get a license.  This article is a nice trip down memory lane. Thanks for the memory.

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
