Central Arizona DX Association


October Meeting

CADXA is the largest ham radio DX club in Arizona with over 130 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).

The October Meeting will be held at 7:00 pm on Thursday night, October 4th, at the PERA Club.  Mike Fulcher, KC7V, will make a presentation on his participation as a referee in the 2018 World Radio Team Championships (WRTC), a/k/a the “Ham Radio Olympics”.  These were held in Germany and 60+ 2-person teams competed in this 24-hour event held the same weekend in July as the International Amateur Radio Union (IARU) contest.  Mike was lucky enough to referee the winning team from Lithuania.  Come and hear about how the WRTC organizers set up a level playing field of identical stations (except for the radios) for this very special event and how Mike stayed awake for 24 hours to do his job as a referee.

Please feel free to arrive early to socialize with your friends.  Refreshments will be served at the break.  Guests are always welcome. 

The new parking lot south of the PERA Club is the place to park for the meeting while building construction continues in the old parking lot.

The September meeting was attended by over 50 members and guests who came to hear Ned, AA7A, and Bud, N7CW, discuss their summer trip to KH1/KH7Z, Baker Island in the South Pacific.  Along with other members of the Dateline DX Association, this team made nearly 70,000 QSOs and may have changed the face of future DXpeditions with their groundbreaking use of the FT8 digital mode.  The trip to this rarely visited Top Ten most wanted DXCC entity was anxiously awaited by DXers around the world, especially in Europe.

The team was told by their U.S. Fish and Wildlife chaperon that it never rains on Baker.  Well, that turned out to be fiction as members of the team had to use some muscle against the side of their tents to keep them collapsing from the rain and wind provided by a surprise gale force rainstorm that destroyed their 80-meter vertical antenna at the beginning of their stay.  Some of their Elecraft radios appeared to have drowned in the rain but proved to be miraculously resilient after being dried out the next day by the intense island heat.

The FT8 story was impressive with a single operator able to run two stations simultaneously on different bands while maintaining rates that could reach 400 QSOs per hour.  No RTTY operation by a past DXpedition has come close to that kind of rate.  A limiting factor seemed to be the failure of too many hams to read the readily available guidelines on how to use the new FT8 “DXpedition mode” and wasted their time and the Baker operators’ time by not following those instructions.

President's Message

Sept. Meeting Recap

Now that the 6-meter Sporadic E season has ended, there is not much DX activity above 17 meters.  Most of the activity during the daytime is on 17 and 20 meters and as the days grow shorter, there is growing activity on the low frequency (LF) bands – 40, 60, 80, and 160 meters.  The latest reports from the solar gurus indicate we have another 1-2 years before hitting the bottom of the sunspot cycle.  That is a good reason to pay more attention to the LF bands where there is nightly activity and DX to work.

We are getting close to the time for convening the CADXA Nominating Committee for 2019.  I encourage members to step up and take a turn as a club leader.  Let me or any of the Board members know of your interest so we can pass it along to the Committee.  After completing my third year as President, I am looking forward to having the word "Past" before my title in 2019.  The timing is important to me because I have recently been elected a Director of the Northern California DX Foundation (NCDXF) and it will take up some of the time I have spent leading the club these past three years. 

We have recently heard from our colleagues at the Northern California DX Club (NCDXC) that CADXA will be tasked with taking a leading role in running the International DX Convention (IDXC) in 2019 in Visalia, CA.  Ned, AA7A, and I will once again organize and run the programs for the convention.  Larry, WO7R, will handle the Banquet Seating responsibilities and XYLs Jan and Debby with assistance from Jim, K7MY, will again run the Prize Room for the raffle. 

These responsibilities for Visalia are time consuming, but have proven to be financially rewarding for the club in the past.  We are looking forward to this opportunity for CADXA's participation.

Mark your calendar for Saturday night, January 19, 2019.  We have reserved the PERA Club that night for the 2019 Awards Banquet.
