Israel

The September before the creation of the State of Israel, the station ZC6AA identified its location as “Tel Aviv, Israel.”

4X and 4Z were activated when the state of Israel was proclaimed, however afterwards some individual operators adopted call signs assuming that the territory was still “Arab Palestine”. The UN Headquarters signed “Jerusalem” in 1947 and “Jerusalem, Palestine” in 1957, with callsigns ZC6UNJ and ZC6UNU.

During the Suez crisis in 1957, some Israeli operators signed in the Sinai with an Israelis prefix, but with a /SINAI appended to their call sign.

Israel can issue a National Israeli call sign in the series 4Z8 to foreign amateurs whose countries participate in the CEPT Recommendation T/R 61-02.

The Israeli Amateur Radio Club (IARC) was founded on February 18, 1948, and is a member at IARU.  Presently call signs are issued within Israel by the Ministry of Communications according to this table:

Call sign block License Category
4X0, 4Z0, 4X2, 4Z2, 4X3, 4Z3, 4Z6, 4X7, 4X9 Special Events
4X1AA–4X1ZZ, 4Z1AA–4Z1ZZ Extra/Class A
4X4AA–4X4ZZ, 4Z4AA–4Z4ZZ, 4Z5AA–4Z5ZZ, 4X5AA-4X5ZZ, 4X6AA–4X6ZZ General/Class B
4Z9AAA–4Z9ZZZ Novice/Class C
4Z7AAA–4Z7ZZZ Technician/Class D
4X8AA–4X8ZZ Honorary
4Z8AA–4Z8ZZ Foreign

In July 2012 a 4Z5 operator was upgraded to class A without a callsign change.

In 1924, Hiram Percy Maxim, President of the American Radio Relay League, realized that amateur radio had become international, and that there should be a global organization to take advantage of that growth. He was also aware that radio frequencies thought to be of little use, which had been assigned to amateurs, were capable of long range communication with low power and simple antennas. This resulted in administrations reconsidering the reassignment of these frequencies from amateur use into commercial and military applications.

In March of 1924 Hiram P. Maxim met in Paris with an international group of talented radio amateurs from France, Great Britain, Belgium, Switzerland, Italy, Spain, Luxembourg, Canada and the USA which made preliminary plans for an international organization to be known as the International Amateur Radio Union (IARU). A Congress was arranged in Paris in April 1925 to create the permanent global amateur organization. Amateur Radio representatives of 23 countries then met in Paris to create the International Amateur Radio Union and to adopt a constitution.

While most of the 23 countries represented at the April 1925 meeting were from Europe, there were also delegates from North and South America, and from Japan. On April 17,1925 the first constitution of the IARU was unanimously adopted. At the final plenary session on April 18 some 25 countries were in attendance. All actions of the organizing Congress were approved and the International Amateur Radio Union was born, with Hiram P Maxim as its first President.

The Pilot Radio Corp. was founded by Isidor Goldberg. He was born in Manhattan, New York, in 1893 and graduated from Hebrew Technical Institute in Mechanical Arts in 1908. From 1910-1914, Isidor Goldberg was a test pilot for Curtiss Aeroplane and Motor Corporation and Curtiss Airways. Afterwards he sold aeronautical supplies and model airplanes. In 1915 Goldberg was granted a U.S. patent for his invention of an emergency lamp.

In 1919, Isidor Goldberg founded Pilot Electric Manufacturing Co. in Brooklyn, New York, to manufacture parts and kits for home radios. In 1930 a second plant was established in Lawrence, Massachusetts. The name of the company was later changed to Pilot Radio and Tube Corp. and, in 1932, to Pilot Radio Corp. By 1936 Pilot products were being sold in more than 90 countries. In the late 1940s and early 1950s plants were built in Britain (prior to World War II), South Africa (by 1953), and Israel (in 1947). All three plants were sold in 1959. Goldberg was president of the company from its inception until his death in 1961. 

As president of Pilot Radio Corp., Isidor Goldberg was a leader in developing and introducing new products and new uses for communications equipment. The company was the first to introduce a civilian short wave radio (WASP, 1925) and a battery-powered, portable radio (1937). In 1930, he also developed long distance ground-to-air communications with his “flying laboratory”.

The 1899 Americas Cup Race was the first time that reporters could send back information on the progress of the race thanks to Marconi…..

From Wikipedia:     The 1899 America’s Cup was the 10th challenge for the Cup. It took place in the New York City harbor and consisted of a best of five series of races between the defender, Columbia, entered by the New York Yacht Club, and Sir Thomas Lipton’s Shamrock, representing the Royal Ulster Yacht Club. Columbia won all three races against Shamrock.

From Wikipedia about Columbia:    Columbia, a fin keel sloop, was designed and built in 1898-9 by Nathanael Herreshoff and the Herreshoff Manufacturing Company for owners J. Pierpont Morgan and Edwin Dennison Morgan of the New York Yacht Club. She was the third successful defender built by Herreshoff.

Columbia had a nickel steel frame, a tobin bronze hull, and a steel mast.

Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) was an American painter and inventor. After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs… More at Wikipedia

In 1832, following a three-year European tour, Samuel F.B. Morse sailed home to America. Tucked away in the hold was Gallery of the Louvre (1831–1833), a massive six-by-nine-foot canvas that would take him 14 months to complete. Morse intended for the painting, which depicted some three dozen of the Louvre’s greatest works displayed together in an imagined museum gallery, to serve as a sweeping art history lesson for the American people. This painting, he was certain, would finally propel him to fame… The rest of the story at Artsy.net

 From Eham Forum… Post by: WF0H on February 23, 2003… I am not sure when this started, but it was well established in the early 1950’s, which were probably the heyday of the 807 tube.  I once had a Johnson-Viking mobile rig from the late 1940’s that had an 807 final in it – a wonderful CW and AM rig, too. In the 1930s, the popular tube was the Model 45. By the late 1950’s, the tube of choice was the 6146, so it probably stared someplace in between those two eras.
