First Ham Satellite -- OSCAR 1 -- Will Join AMSAT's 50th Anniversary Celebration at Dayton:
A working prototype of OSCAR 1, Amateur Radio's first satellite, will
be on display at AMSAT's Dayton Hamvention booth. AMSAT's exhibit will
be in Building 1 (Maxim Hall) at the Greene County Fairgrounds and Expo
Center in Xenia, Ohio. OSCAR 1 (Orbiting Satellite Carrying Amateur
Radio) was launched into orbit in 1961, at the dawn of the Space Age.
Built by a group of California-based radio amateurs for about $60,
OSCAR 1 was the first nongovernmental satellite. It transmitted a
simple "HI" in CW for nearly 20 days and was heard in 28 different
countries. W1AW Station Manager Joe Carcia, NJ1Q, recently had to
troubleshoot a problem with ARRL's OSCAR 1 in preparation for its
Dayton appearance in a special "OSCAR Park" display commemorating
AMSAT's 50th anniversary. He said it was a "rather humbling"
"Apparently, OSCAR 1 was not transmitting properly," Carcia said. "So,
I took it back into the shop, changed the power cable, and checked the
transmitter. I had to tweak it just a bit." Carcia said the satellite
Only three OSCAR 1 satellites were made. One was launched into orbit,
of course, while the Smithsonian Institution houses the other.
"Assuming it doesn't get bounced around too much en route, it will be
transmitting a chirpy 'HI' on 145.224 MHz," Carcia said. "The load is a
50 W resistor, so you can copy it about 50 feet or so away from the
AMSAT will present Amateur Radio satellite operation demonstrations
outside the main entrance of Maxim Hall, 8 AM - 4:30 PM, on all three
days of Hamvention. "AMSAT will be demonstrating actual contacts with
the operational amateur satellites," AMSAT said in its weekly AMSAT
News Service newsletter. "We especially want to invite youth to make a
contact via an amateur satellite. All are invited to observe,
participate, and ask questions."
AMSAT will hold its forum in Room 2 on Saturday, May 18, starting at
12:10 PM EDT. AMSAT Vice President of User Services Robert Bankston,
KE4AL, will moderate the session.
