Due to the ongoing situation with COVID-19, the May meeting will be held virtually using Zoom. The meeting will be Thursday night, May 6th starting at 7:00 pm (0200Z). You can begin checking in at 6:30 pm and visit informally with other club members on Zoom until the meeting starts. We often begin our in-person and now Zoom meetings with introductions and maybe a “brag” question to the group.  We will have this stage from 6:30 to 7:00 pm, at which time our presentation will begin. The club business meeting will be held after the presentation.   Please turn off your computer camera and microphone when the formal part of the meeting starts. The link to the Zoom meeting will be sent to all members just prior to the meeting. Our meetings are open to all. If any of you reading this would like to join via Zoom or would like any other information about CADXA, send me an email: aa4q [at] .

The May 2020 CADXA presentation will be “Ferrites & Common Mode Chokes” Kevan Nason, N4XL.

It was a newly discovered interest in contesting that started Keven Nason, N4XL, on his quest to understand the concepts behind advice offered by successful hams.  He sought to discover the reasons why he was being beaten so badly by people using shacks similar to his.  It turned out there were many.

He joined the U.S. Navy shortly after being licensed in 1975.  He found it difficult during his 20-year career to work DX while onboard submarines. He was able to set up dozens of portable and fixed stations when on shore following standard “common knowledge” practices, some worked well, and some didn’t. The Naval Nuclear Propulsion program taught him if you understood why something was done, then you could make better decisions when faced with unusual circumstances. After deciding to achieve competitive contest scores he applied that philosophy to the design and operation of his own shack. His research rewarded him with many Southeast regional contest wins and by often finding his call in the North America Top 10 list for his chosen category.  Those results have been achieved using a modest station of a Kenwood TS590 transceiver, tribander at 50 feet, an elevated vertical, some wire antennas, and a better grasp of how to make them work as they should.

The April program was presented by W3LPL,  "HF Ionospheric Propagation”. The replay is available at

CADXA has several year-long on-the-air activities set up similar to CQ’s DX Marathon. This allows members to track their progress working DX against other members. It encourages working the common ones again every year in between chasing the really rare DX entities. Also, someone with a smaller station working lots of casual QSOs might beat out a DXCC Honor Roll guy with a KW and a ton of aluminum in the air. Tune in to our meeting to see this month’s status!

​In this day and age, clubs may be looking for socially distanced speakers.  At CADXA, many of our members have presentations on the world of DXing, QSLing, Contesting, Station Construction, and related subjects ready to present to your club.  We know how to present via programs like Zoom.  Contact us through our website or email us at cadxainfo [at] or direct me at aa4q [at] for details.

See you on Zoom for the May meeting.

President's Message

CADXA is the largest ham radio DX club in Arizona with over 140 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).
