BY DAVE BROWN, W7FYW,* AND BOB WERTZ, NF7E
L
ast summer, the Northern Arizona DX Association
(NADXA), our local DX, radiosport, and contesting club,
began a discussion of creating a special event to tie in
with Lowell Observatory’s “Year of Pluto.” Lowell Observa-
tory, located in Flagstaff, was used to discover Pluto back in
1930, and was celebrating the 85th anniversary of the dis-
covery in 2015, along with last July’s fly-by of Pluto by NASA’s
New Horizons spacecraft. Lowell Observatory decided to cel-
ebrate both events, calling it the Year of Pluto.
When we approached the observatory staff with the idea
of having an amateur radio event centered around their cel-
ebration, they were very receptive and welcomed us to their
campus for the nine-day event, which was to run from
December 5-13.
On the Air
We had scheduled each operator for at
least a one-hour time slot. Everyone
knew when they were to operate before
the event started and that saved a lot of
confusion and waiting around for a sta-
tion to be available. We started our
operations on 20 and 17 meters. It was
slow to start, but after a short period,
contacts starting piling up. Then here
they came! If you have never been on
the other side of a pileup, you are miss-
ing out on pure terror. It really does
improve your ability to operate. By the
end of the nine-day event, we had com-
piled over 4,600 QSOs, worked all 50
states and 65 countries, including over
350 contacts with Japan. A lot of inter-
est in Pluto from around the world! Not

t the 2015 Dayton Hamvention®
Youth Forum, we had a special
international guest presenter.
Then 17-year-old Tom Jose, VU2TO,
wowed the audience with his amazing
resumé and his stories of helping the
police and emergency communica-

situations.
Many of my young presenters contin-

after the Dayton Youth Forum. This is
one happy, side perk of having moder-
ated the Dayton Youth Forum for the
past 29 years. Tom has kept me post-
ed on his visits to schools in his ongo-
ing efforts to introduce ham radio to stu-
dents in India. His latest communiqué
had me beaming with pride about this
young man’s accomplishments.

do: First, get transmit audio from the computer to the radio.

USB interface, but West Mountain Radio <http://www.
