1980’s Boomboxes
Terms like “wow & flutter”, “soft eject”, “high-speed dubbing”, “CrO2“, and “auto-reverse” are retired now, gone from today’s audio equipment lexicon. Some say that’s a good thing. I still have a soft spot for...

Are you concerned that your Wi-Fi router is causing cancer? Worried that your smart electric meter is giving you headaches? There is a lot of pseudoscience, crazy theories, and false information out there when...
I use GR3 and GR2 Analyst on my PC (see “Commercial Radar Software & Apps” on the WX page), but since I’m often caught without a PC, and since we’re heading straight into severe...
I’ve been using RF sim 99 (aka RFSim99) for over a decade, and it’s proved invaluable again and again during that time, and continues to do so. RFSim99 is a freeware RF simulation software utility....

Almost everyone has heard of FM, but not everyone has heard of FSK. Frequency Shift Keying is a modulation scheme which utilizes changes in the frequency of the carrier wave to communicate data. For...
Coaxial cables, antennas, amplifier inputs and outputs, typically have either a 50 ohm or 75 ohm characteristic impedance. Why? It all comes down to the characteristic impedance value for maximum power transfer being 30...
It seems that the ARRL and a number of individuals have been taking a serious look at harmonics and other spurious emissions from various ham transceivers, including the ubiquitous Baofeng range of handheld transceivers....
