Middle Country Public Library in Centereach

Actress Hedy Lamarr co-patented frequency hopping with
piano composer George Antheil in 1942.
Their system used a player piano roll to change between 88 frequencies to make
radio-guided torpedoes harder to detect and jam.
You are invited to attend Radio Central Amateur Radio Club's
April meeting on Wednesday April 24
at 6:30 PM at the Middle Country Library in Centereach.
Our April meeting topic is Spread Spectrum communications. Our guest speaker will be Bill Bock, a senior applications Engineer at Rohde and
Schwartz. Spread spectrum was originally conceived by film star Hedy Lamarr during the World War II era to provide secure communications for the
Allies. Today Spread Spectrum is used in a broad array of military and commercial applications. Join us at the April meeting to learn more about
this fascinating topic.
Radio Central Amateur Radio Club meetings are open to non-members as well as members.
