Kol Yisrael
Kol Yisrael was originally an underground Haganah radio station that broadcast from Tel Aviv. It started consistently broadcasting in December 1947 under the name "Telem-Shamir-Boaz", and was renamed to "Kol HaHagana" ("Voice of the Haganah") in March 1948. With Israel's declaration of independence on May 14, 1948, it was transformed into the official station Kol Yisrael. Another station named Kol Yisrael operated in Haifa, and was renamed "Kol Tzva HaHagana" (Voice of the Defense Force).
