CADXA members,

Our 2022 meetings will be held on the first Thursday of each month, formal meeting starting at 7PM/1900 AZ time, but show up early, in person, or on zoom, to socialize! 

This month's program:

Don’t miss our next meeting on October 6th.  Glen Popiel KW5GP is returning to present on Arduino: The Next Generation.  We look forward to hearing the new and advanced projects in the ham shack that he’s come up with for Arduino devices.

On August 4, Glen Popiel KW5GP presented on Arduino Basics for Amateur Radio. Glen is the author of the High Speed Multimedia for Amateur Radio, Arduino for Ham Radio, and More Arduino for Ham Radio books sold by the ARRL. He gave an overview of some of the projects that can be created with Arduino boards in Amateur radio to help control and automate ham shack functions to small transceivers. The Arduino platform fits perfectly in the ham toolbox to experiment and home brew electronics. If you missed the meeting, the recording at

In other CADXA news:

Several CADXA members have been involved with the special events for the Navajo Code Talkers which are celebrated every August 14th.  Of the 400 Code Talkers who served in WWII, only 3 are still alive.  This year, they also had groundbreaking on a new museum in Tse Bonito, New Mexico.  For more information, visit

On September 1st, Arnie Shatz N6HC presented DXpedition Medic and Operations.  He shared the steps he takes to prepare that are needed to go on many of the DXpeditions he’s been a member of.  A lot of planning is required, including medical history of everyone and a well-organized suitcase of medical supplies.  Arnie shared slides and stories of a few incidents he’s encountered over the years. Following the main presentation, Bill Clark K6WSC, Arizona QSO Party Chairman, shared information on the upcoming AZQP on October 8th.  Full information can be found 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. 

Our repeater in Mesa is on the air and open for use with callsign K5VT/R at 147.32+ with 123.0 PL.

For 2 years we met on zoom. Many of the prior CADXA programs are available for replay at:

President's Message


Central Arizona DX Association

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).
