Special Event Callsign N3P
Π Day Special Event
David Sarnoff Radio Club,
Princeton, New Jersey – 3.14.2024

What are we celebrating?

On March 14th, it is “3.14” so say “Happy Pi Day!”

The David Sarnoff Radio Club hosts a special event station every year on March 14th in conjunction with the Princeton Pi Day & Einstein Birthday Party held in Princeton New Jersey.

AI Program imagines… what would Einstein look like as a ham radio operator?

Albert Einstein was born on March 14th, 1879, in Ulm, a city in what is now Germany. He lived and worked in the town of Princeton, NJ, USA from 1933 to his death in 1955, faculty at the Institute for Advanced Study, a private institute of learning near town. Princeton celebrates their long-time resident and the amazing coincidence of time like no other city on earth! There may be many celebrations in downtown Princeton, from PIE eating, to Pi recitation, to Albert Einstein costumes… You may see it on the square. It may not be a massive celebration, but it will be energetic, and that’s the same thing.

The David Sarnoff Radio Club, a club in the Princeton area, will join in the celebration with an amateur radio special event station, N3P. It may be irrational to celebrate pi, but why restrict festivities to one community? We want everyone to join in the fun — at the speed of light!

David Sarnoff and Albert Einstein, a pi connection?

When and How are We Celebrating in 2024?

Listen for our Special Event Station, Callsign: N3P (November three Papa) starting 0000 UTC on March 14, 2024. We use UNIVERSAL TIME for this special event to honor Albert Einstein, the discoverer of universal laws! (in New Jersey that will be 8 PM Eastern Daylight Time on Wednesday, through 7:59 PM EDT Thursday.)

There is no special exchange for Pi Day, just say Happy Pi Day and maybe tell us what State/Province, Country, or grid square you are celebrating in — that’s the only exchange we need!

Eating pie is traditional, but completely optional.
