2025 was CADXA's 50th Anniversary year!!!
We are the largest ham radio DX club in Arizona with over 100 members, many of whom are on the ARRL's
DXCC Honor Roll and several members have traveled to distant places to activate countries with minimal or no amateur radio activity. We encourage any ham interested in DXing to join our club, learn about the many aspects of talking to hams around the globe and 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).

WELCOME to the Central Arizona DX Association website! We appreciate your visit and encourage you to join us at our meetings or on Zoom.
The next CADXA meeting will be on Thursday, November 5th at the Scottsdale Senior Center located at 1700 N Granite Reef Rd, Scottsdale. Doors open at 6:00 pm for socializing; the program generally starts at 6:30 pm. Guests are always welcome.
The November program will be "New Developments in the WSJT Suite of Digital Programs" by club member David Christle, KD0BTO. David has been actively involved with Joe Taylor's WSJT program development team. He will discuss the newest program in the suite called "JTTY."
For two decades, the major modes from the WSJT project have followed the same pattern: transmit in one period, listen in the next, decode at the end of the cycle. JTTY breaks that pattern. It was announced on September 23, 2026 with WSJT-X 3.2.0-rc1. It is a keyboard-to-keyboard mode that transmits when you press a key and prints text as it arrives, just like RTTY. The development team describes the goal as the operating feel of RTTY with much better weak-signal performance and a much lower error rate. The target audience is clear: RTTY contesters who have watched FT8 and FT4 take over activity but still prefer running with function keys and a serial-number exchange.
