DQRM of E44OM

 


 I have been checking DXHeat DX cluster for E44OM and this morning I saw them spotted on 10 meters at 28.005 to be exact. I double clicked on NA5B Web SDR to see if I could hear the action, if so then hit the shack to see if I could break the pileup and get E44OM in the log. When tuned to the frequency I was very disappoint to hear a solid carrier being transmitted on the exact frequency for E44OM. Some folks have way to much time on their hands.

EiffelTenna is in Practical Wireless

My bespoke portable HF antenna, called the EiffelTenna, is featured in the October issue of Practical Wireless. I was inspired by a video of Jim W6LG on his Youtube Channel as well as the further work of Jason VE5REV via Twitter (X). It’s a fun build, inexpensive, is very portable, and works 40, 20, 15 and 10 meters. I use Faraday Cloth for the counterpoise and place the tripod directly on it.

The 40 meter operation works as a center-loaded vertical, something I posted on regarding the inductor coils recently. If you intend to build the EiffelTenna, check out that article too. The EiffelTenna base alone would be good for Technicians since it works on 10 meters without a whip or coil. A stainless steel whip on top of the tripod makes for a solid vertical with its own mounting base. For windy conditions, I use some 1lb ankle weights attached to each tripod leg using the built-in velcro straps.

Shown below is the EiffelTenna deployed for testing on my driveway. (Click for full image) It is setup for 40 meters using a JPC-12 inductor coil. Others work as well or better so this was just the option used here because it’s adjustable. The RF sweep has the coil bypassed using KB9VBR’s trick for use on 20 meters. Nearly 50 ohms with SWR of 1.06 at 14.154 MHz. Note how relatively small the counterpoise cloth is in this picture.

This full antenna system packs down into an inexpensive camera tripod bag ($16 via Amazon). A RigExpert antenna analyzer is underneath the Faraday Cloth for matching in the field. Coax from RG-316 with a ferrite bead choke is wound on a wire winder printed by my public library for the cost of resin ($4). Blue ankle weights were purchased at Academy Sports while on sale.

The EiffelTenna uses traditional vertical antenna concepts with unexpected objects serving as both a ground mount and a radiating element. Thanks Jim W6LG and Jason VE5REV for the inspiration!

The Communicator September – October 2025

Back With a Fall Issue

This publication, "The Communicator" from Surrey Amateur Radio Communications (SARC), serves as a bi-monthly electronic periodical for amateur radio operators. It covers a wide array of topics, including historical figures in radio. This month Jonathan Zenneck and Edwin Armstrong. In this issue we also provide technical explanations of radio propagation phenomena such as the Gray Line and solar indices, and practical guides for amateur radio activities like building antennas. We take a closer look at specific radio equipment (Baofeng, Icom, and Anytone), and engaging in digital modes like FT8. 

The Communicator also features emergency preparedness strategies, and the diverse interests and community focus within amateur radio. Furthermore, it touches upon innovative developments like the Linux Handie Talkie (LinHT) and the importance of in-person technical conferences for knowledge exchange.

Now read in over 165 countries, this issue brings you 130 pages of Amateur Radio content from the Southwest corner of Canada and around the globe. With less fluff and ads than other Amateur Radio publications, you will find Amateur Radio related articles, projects, profiles, news, tips and how-to's for all levels of the hobby.
