Ham Radio Allows Earthlings And Astronauts Chat Away

Astronaut Doug Wheelock

The International Space Station cost more than $100 billion. A ham radio set can be had for a few hundred bucks.

Perhaps that explains, in part, the appeal of having one of humankind’s greatest scientific inventions communicate with Earth via technology that’s more than 100 years old. But perhaps there’s a simpler explanation for why astronauts and ham radio operators have been talking, and talking, for years.

NASA astronaut Doug Wheelock was just a few weeks into his six-month mission at the space station when feelings of isolation began to set in.

Wheelock would be separated from loved ones, save for communication via an internet phone, email or social media. At times, the stress and tension of serving as the station’s commander could be intense.

One night, as he looked out a window at the Earth below, he remembered the space station’s ham radio. He figured he’d turn it on — see if anyone was listening.

“Any station, any station, this is the International Space Station,” Wheelock said.

A flood of voices jumbled out of the airwaves.

Astronauts aboard the space station often speak to students via ham radio, which can also be used in emergencies, but those are scheduled appearances. Some, like Wheelock, spend their limited free time making contact with amateur radio operators around the world.

“It allowed me to ... just reach out to humanity down there,” said Wheelock, who interacted with many operators, known as “hams,” during that stay at the space station in 2010. “It became my emotional, and a really visceral, connection to the planet.”

The first amateur radio transmission from space dates to 1983, when astronaut Owen Garriott took to the airwaves from the Space Shuttle Columbia. Garriott was a licensed ham who, back on Earth, had used his home equipment in Houston to chat with his father in Oklahoma.

Over the last 10 years, ham radio has become more popular, experts say, with about 750,000 licensed amateur operators across the U.S. (not all of whom are active on the air). Helping to drive that interest: emergency communications.

“Ham radio is when all else fails,” said Diana Feinberg, Los Angeles section manager for the American Radio Relay League, the national association for amateur radio. “Unlike other forms of communication, it does not require any kind of a switched network.”

But for some hams, the allure is the opportunity to connect with people all over the world — or even above it.
