W7P - the Year of Pluto Special Event scheduled for December 2015

Pluto and Flagstaff, Arizona are forever linked in history. On February 18th 1930, the astronomer Clyde Tombaugh discovered Pluto at Lowell Observatory in Flagstaff using a blink comparator and photographic plates taken at the observatory. Eighty five years later, NASA's New Horizons probe reached the Pluto system, imaging Pluto, Charon, and the other small moons.

In celebration of the 85th anniversary of its discovery and the arrival of New Horizons probe, the year 2015 has been designated the "Year of Pluto". To celebrate, the members of the Northern Arizona DX Association (NADXA) are sponsoring a special event using the call sign W7P from 0001Z December 5th to 2400Z December 13. Operations will take place at Lowell Observatory from inside the Pluto discovery telescope dome, as well as from the homes of club members using both CW & SSB. There will also be a very special guest operator; Doug Tombaugh N3PDT, nephew of Clyde Tombaugh who will operate for three days during the early part of the event.

Any station who contacts W7P at least once will be eligible for a beautiful glossy commemorative certificate printed on heavy card stock that features a New Horizons image of Pluto, pictures of Lowell telescopes, a brief history of Pluto's discovery, and a description of the New Horizons communication system. A QSL card will be included with each certificate request. The certificate is available for $5 for USA addresses and $7 for DX addresses. Single QSL card requests require an SASE or a minimum $2 donation for both USA and DX addresses.

Please send Certificate and QSL Card requests to:

Dedicated to the Enjoyment of DXing and Contesting

The Northern Arizona DX Association exists to help hams enjoy the fun of radio contests and DXing. Meetings are open to anyone interested in these pursuits.

In addition to chasing DX and taking part in contests throughout the year, our members also take part in DXpeditions when they get the chance.  Please visit our Photo Album to see some of the great DX locations we have operated from.

Back in 2000, we organized a new special operating event; Route 66 On the Air! to celebrate the highway's 75th anniversary. It turned out to be wildly popular and quickly outgrew our small club. See our Club Activities for details on how to participate or visit the current sponsor, the Citrus Belt ARC.
