The Northern Arizona DX Association will be continuing with year six of the 10-year special event
countdown to the 100th anniversary of the discovery of Pluto by Clyde Tombaugh at Lowell Observatory in
Flagstaff, Arizona. This annual 9-day event is held each February through the 2030 anniversary. This
year's event will take place February 14-22, 2026 (UTC).
Club members operated from Lowell Observatory and their home QTHs using the special event callsign W7P. Doug Tombaugh (N3PDT), Clyde Tombaugh's nephew, operated during the event as W7P/Øand those contacts with Doug or his team counts as an additional endorsement on the certificate and can also be used as a wild card for any previous missed year. A beautiful color certificate suitable for framing and endorsement stickers for each year worked during the event, are still available. 2026 was a banner year for the event with more QSOs, both CONUS and DX, than any previous year. W7P: 4250 Contacts - W7P/Ø: 2297 Contacts - 81 DX Entities |
