A Simple DC Power Polarity Checker
Save your equipment from reverse polarity disasters
.
John Burnley, NUØV

One of the most common mistakes I make while building simple radios is incorrectly hooking up my power supplies. Adapter supplies sometimes have the polarity reversed. Some are even ac and not dc. I try to check the polarity with a volt ohm meter (VOM), but if I forget, there can be chaos. My operating over the past 2 decades has been with homebrew QRP radio kits from clubs or vendors. These use the common barrel connectors that have powered amateur radios and accessories for decades. There are technologies like Anderson Powerpole connectors that would alleviate polarity issues, but the cost of the connectors and cables were more than the radios themselves. I needed an easy, inexpensive, and consistent solution.

Anderson Powerpole Polarity Tester
Dino Papas, KLØS

Historically, hams have had to deal with manufacturers using many different radio and accessory power connectors that were not standardized. This made it difficult to quickly power and interface radios and accessory equipment at different locations, whether at your own radio desk, in your vehicle, and especially during emergency and community support activities.

To address this problem, the world of ham radio public service, including ARES®, adopted Anderson Powerpoles as their de facto standard for power and accessory connectors during emergency operations. A Powerpole polarity tester like the one described here can immediately and safely tell you if the mating connector is wired incorrectly with a reversed dc polarity.

Do-It-Yourself NMEA Based GPS Time Display
This Maker-Faire style time display project is an extension of the Themis Project
.
John C. Westmoreland, AJ6BC

This article explains and examines a DIY style of project in detail, with a simple programming example and some low-cost module components that can be used to make a nice high-quality display to show the current local time, or for that matter can be modified to display time in any zone or customized to display what the user/programmer wishes. The tools required to make the display will be explained in enough detail that users, programmers, and readers can customize the display in any form they wish.

The Story of the J68HZ Dream
William J. Schmidt, K9HZ/J68HZ

It is every contester’s dream to own a very capable station in a desirable part of the world that is competitive, maintenance free, and a place that the rest of the non-ham family wants to visit. To that end, my wife and I set out to find that place. Our search started more than 20 years ago with our first trips to the Caribbean. Our family loves the sun and water, so we made arrangements to go to the Caymans, Turks and Caicos, Bonaire, St. Lucia, Curacao, and St. Vincent. Each island has its own charm and feel. I had the opportunity to operate at many of the contest stations on these islands, and I realized the Caribbean could be the perfect location of another competitive contest station. Our observation was that many of the locations were either good for the family or good for contesting, but few checked both boxes.



What’s the Buzz?
Eclectic Tech  Episode 27 Preview  February 11
Learn about extremely slow CW – otherwise known as QRSS – with Clint Turner, KA7OEI. For years, amateurs have been sending slow Morse at low power levels to test propagation at HF frequencies and below. Find out what the QRSS community is doing today and how you can join in the fun.
Also, when it comes to your station computer, what is an “audio device?” Is it a microphone, a headset, or something else? The answer is “all of the above,” but the details may surprise you.

 
On the Air  Episode 14 Preview  February 11
This episode is loaded with information about what to look for when shopping for an antenna tuner. Here’s a peek at the kind of info you’ll get:

Antenna Tuner Shopping Tips: Continuous Power or Peak Power?

  • Antenna tuners carry “Continuous Power” and “Peak Power” ratings. Continuous power ratings are usually lower than PEP (“peak envelope power”) ratings and indicate the power that the tuner can handle for an extended time. PEP indicates the maximum power the tuner can tolerate for a short time.
  • When to Buy for Continuous Power. If you plan to operate at high continuous power levels, get an antenna tuner that is rated for the same continuous power you think you’ll be using at your station. If you’re using a 100 W transceiver, make sure your tuner is rated for a minimum of 100 W continuous power. You’ll need it if you’re operating digital modes like FT8, because they require your radio to constantly generate output, possibly for an extended time.
  • When to Buy for Peak Power. “PEP,” or “peak envelope power,” is only maintained for a short time. If you don’t think you’ll ever want to operate at high continuous power levels (for example, if you mainly operate SSB or CW), you can save money by choosing a tuner based strictly on its PEP or SSB power rating.
