Surviving the Switch to LED Lighting
By Kirk A. Kleinschmidt NT0Z
How inefficient is incandescent lighting? Kirk explains, “Common incandescent bulbs emit just 15 lumens per watt, which is an electrical efficiency of about 2%. In ham antenna equivalents, that’s on par with a vehicle-mounted mobile whip on 80 meters, or a full-wave HF loop made from barbed wire and pinned to the ground! An LED bulb typically produces at least 75 lumens per watt, which is vastly more efficient.” But the price for this efficiency is radio frequency interference: RFI. Kirk has guidance for coping.
UK Local Radio: A Mixed Bag
By Chrissy Brand
In her travels around the UK and the EU, Chrissy’s ear is always tuned to local radio. So, how is local UK radio stacking up? She finds that “some stations are more local than others, and some seek to innovate where others merely imitate what is already heavily represented across the dial.”
Revisiting the Airspy HF+ and YouLoop Indoor Antenna
By Georg Wiessala
Software Defined Radios (SDRs) have redefined the listening RF landscape breaking all kinds of reception barriers. Georg finds that coupling the best SDRs with the best indoor receiving loop antennas takes the radio hobby to even greater heights.
Multiple Satellite Reception from a Single Ku-Band Antenna
By Mike Kohl
It all started for Mike back in the early 1980s when building C-band multi-satellite receiving antennas for installations in Alaska. Since then, he has been pushing the limits of what a single Ku-band dish can receive. It actually has to be seen to be believed.
Northwest US AM Broadcast Radio History
By Richard Fisher KI6SN
The northwestern US 100 years ago was vastly unpopulated with some of the most rugged territory in the country. The fastest way to travel then was by radio. While many eastern US radio pioneers get most of the ink in history texts, the northwest US was there, step-for-step for the radio revolution. Richard details some of the earliest history of AM radio in Washington, Oregon, Idaho, and Montana.
The Moscow Radio Laboratory and the Birth of Radio Moscow—Part One
By Scott A. Caldwell
The Russian Revolution of 1917 just happened to coincide with the rapid development of the first electronic revolution—the global introduction of radio. Scott traces the development of electronics in Russia and the inevitable collision of Socialism and mass communications.
