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 members,

our August 2022 meeting will be held on the first Thursday of the month, August 4th, 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 August 4th.  The presenter will be Glen Popiel KW5GP 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.

Glen will present remotely, so we will do our brag session before 7PM and start his presentation right at 7PM, then after a snack break, we will hold the business meeting.

In other CADXA news:

On June 2, Bill Straw KO7SS presented on the upcoming 3Y0J Bouvet Island
2023 Dxpedition.  He talked about the team that has been assembled, some
of the plans of their trip, as well as the preparation they are doing. 
The ship, tents, radios, and antennas have all been reviewed for the
upcoming trip in January 2023.  We are all very excited to follow their
progress to activate Bouvet Island, #2 on the DXCC most wanted list.  If
you missed the meeting, the recording is available for viewing at

On July 7, Tim Duffy K3LR presented Antenna Building at the general
meeting.  Tim is known for being the CEO of DXEngineering as well as the
owner of the K3LR Multi-Multi Contest Station.  He covered basic antenna
types and fundamentals first, followed by descriptions and pictures of
several antennas that were built and in use at the K3LR station.  If you

Our meeting location for 2022:

Bethany Lutheran Church
4300 North 82nd St.
Scottsdale, AZ 85251
33.49913166046699, -111.90521877586293
Located approximately 2-blocks west of Granite Reef Road, half-way between Indian School and Camelback Roads. Again, monthly meetings will be 7PM on the first thursday unless announced otherwise.

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: https://www.youtube.com/channel/UC9nMKw-3r3ygdLWxsGcqV2A
