Calling all amateur radio operators: Fermilab employees are taking to the air waves.

From December 2-17, the Fermilab Amateur Radio Club, whose membership includes laboratory employees, former employees and guests, is commemorating the lab’s 50th birthday with two weeks of ham radio activity. Tune in at the right frequency at the right time, and you could communicate directly with a member of the Fermilab community to ask your burning questions. How does an accelerator bring particles to near light speed? When did the universe begin? How did Fermilab begin?

You just might hear a friendly voice—or receive a Morse code message—at the other end.

The club has established a call sign for this special two-week event: W9F. They will operate daily on all frequencies and modes—voice, Morse code and others. The anticipated frequencies of operation are 14.260, 14.340, 7.250 and 7.275 MHz. There may also be operations on 7.040, 10.130 and 14.040.

“Amateur radio is the original electronic social media,” says Fermilab engineering physicist Kermit Carlson. “It’s practiced as an avocation without pay or pecuniary interest by people worldwide.”

According to ARRL, the national association for amateur radio, there are more than 800,000 amateur radio operators in the United States and roughly 2 million worldwide—in virtually every country.
