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).

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:
