Remembering Ham Radio Magazines
Ham radio magazines have been part of my life for fifty years. The best of them all was actually called “Ham Radio Magazine”. Remember it? Read more
Loop Amplifier Input Impedance – Keeping It Low
Popular circuits do a pretty good job of providing low loop amplifier input impedance. This means you can use these to keep a loop in short-circuit wideband mode quite easily. Read more
Dipole Versus Wideband Magnetic Loop Performance
Dipole versus wideband magnetic loop performance simulations show that a good active loop will stack up fairly well on the HF ham bands. Read more
Magnetic Loop Magic Continues – Wideband Next
Looking back, I have had a lot of fun with magnetic loop magic. Next up, I will try my hand at wideband active loops for diversity reception. Read more
Watching Digital Radio Signals
If you enjoy looking at signals, you will love watching digital radio signals. Many of these exist across the radio spectrum, from long waves to microwaves. Read more
Translation Tool – Reading Swedish Radio Magazines
Using free translation tool, you can now read foreign radio magazines in your native language. I translated the Swedish radio experimenters magazine Resonans. Read more
Faraday, Maxwell – Scientific Heroes Remembered
Take a moment to reflect on the 19th Century giants Faraday, Maxwell. These wonderful scientists laid the foundations for modern physics and our radio hobbies. Read more
Red Pitaya Ham Radio Homebrew
Take the leap into Red Pitaya ham radio homebrew. Most of what you need for a DIY receiver or transceiver is on this amazing little device. Read more
Ham Radio Beamforming with Phased Arrays
Antenna phasing is used for ham radio beamforming and shortwave listening, especially on the lower bands where conventional beams are not feasible. Read more
