Year Three of the 100th Anniversary 10-Year Countdown Special Event
The 93rd Anniversary is 11-19 February, 2023 (UTC)
This is the 3rd year of the 10 year special event celebrating the discovery of Pluto.
Members of the NORTHERN ARIZONA DX ASSOCIATION will be operating from Lowell Observatory and their home QTHs
operating on most bands and modes from Feb 11th thru 19th. We will be using W7P as our callsign and will also
have W7P/0 operating from Kansas City. The W7P/0 station is managed by Doug Tombaugh, N3PDT, who is the nephew
of Clyde Tombaugh, the astronomer that discovered Pluto back in 1930! There are a number of new telescopes at
Lowell Observatory for the public to use including the beautiful 8" Moonraker refractor shown below. Also, there
is a 32" reflector with a short focal length as well as others. More details can be found on our callsign W7P on
QRZ or on our website at www.nadxa.com under activities. We hope to have you in our log! Be sure to get this
years QSL that shows Clyde looking through his homemade 9" telescope back when he was 22 years old.

Last year we had over 7000 QSOs including 58 DX entities, and over 17,000 hits on QRZ.com! This year we
hope to surpass those numbers.
