Let Portable Antennas give you a Noise-Free Vacation
By Keith Baker KB1SF/VA3KSF
An increasing cacophony of mostly man-made RF noise on our HF bands makes it ever more difficult to hear particularly weak incoming stations, sometimes to the point of making reception of favorite shortwave or ham DX stations all but impossible at home. Keith shows us how you can take a break from noise using portable antennas that really work.
What You Should Know before Investing in an Antenna
By Richard Fisher KI6SN
Whether you are a relative newcomer to amateur radio, SWLing, TV DXing or VHF-UHF scanning, or are a seasoned card-carrying veteran, only you will know the antenna parameters best suited for your amateur station or listening post. Your own passions, needs, capabilities, real estate, budget and a jillion other factors inform your antenna choices. Richard helps sort out the options and explains how to get the most S-units per dollar spent in pursuit of DX.
Wi-Fi Radio Primer Part 1
By Thomas Witherspoon K4SWL
Always a hard-core shortwave radio listener, Thomas likes the tactile experience of turning the knobs of the shortwave, tuning in stations across the globe. So, when online listening became popular, it never occurred to him to give it a try. Then, at the 2012 Winter SWL Fest, an excellent presentation on the merits and technologies behind Wi-Fi radio intrigued him. After downloading and installing the Pro version of the TuneIn radio app, he had to admit, it was a pretty powerful listening experience…one he could easily get used to.
Piggy-Bank Ham Radio Part 1
By Cory GB Sickles WA3UVV
After hearing someone bemoan the “high cost” of amateur radio and how such a “prohibitive expense” was preventing many from becoming hams, his knee jerk reaction was, “Really?” Sure, if you’re referring to a super-mega-über contest station, then he might agree, but just to get started, you don’t need deep pockets—just some preparation and some well-placed effort. Cory outlines a “cheap and dirty” way to start enjoying HF—with the basic Technician class license. Just as ham radio itself has no barriers as to age, the ideas he shares can work for anyone, whether you’re a student, retiree or somewhere in between.
Multiple FTA Satellite Reception Techniques Revisited
By Mike Kohl
The most cost effective way to get into Free-to-Air satellite reception is with 75 to 90-cm antennas for most Ku-band reception because they’re cheaper and shipping costs are less. But needing to monitor multiple FTA satellites forces a decision about whether to use multiple Ku-band antennas linked together with a DiSEqC switch, or to motorize one or more antennas. Which Ku-band satellites do we actually watch on a regular basis? After the busy Galaxy 19 satellite at 97 degrees West, what satellites do we need continuous access from on a 24 hour basis? Mike shows us how to properly set up a motorized Ku-band dish or use a DiSEqC switch.
