WLW RADIO Crosley Broadcasting Corporation

WLW Radio Tower
On March 22, 1922, Crosley and his Crosley Broadcasting Corporation began broadcasting with the new callsign WLW and 50 watts of power. Crosley was a fanatic about the new broadcasting technology, and continually increased his station's capability. The power went up to 500 watts in September 1922, 1000 watts in May 1924, and in January 1925 WLW was the first broadcasting station at the 5000 watt level. On October 4, 1928, the station increased its power to 50 kilowatts. Again it was the first station at this power level, which still is the maximum power currently allowed for any AM station in the United States.
At 50 kilowatts, WLW was heard easily over a wide area, from New York to Florida. But Crosley still wasn't satisfied. In 1933 he obtained a construction permit from the Federal Radio Commission for a 500 kilowatt superstation, and he spent some $500,000 (at least $17 million in 2010 dollars using a CPI conversion factor of 0.13 building the transmitter and antenna.
It was the first large amplifier used in the United States for public domestic radio broadcasting and was in operation between 1934 and 1939. It was an experimental amplifier and was driven by the radio station's regular 50 kW transmitter. It operated in class C with high-level plate modulation. The amplifier required a dedicated 33 kV electrical substation and a large pond complete with fountains for cooling. It operated with a power input of about 750 kW (plus another 400 kW of audio for the modulator) and its output was 500 kW.
In January 1934 WLW began broadcasting at the 500 kilowatt level late at night under the experimental callsign W8XO. In April 1934 the station was authorized to operate at 500 kilowatts during regular hours under the WLW call letters. On May 2, 1934, President Franklin D. Roosevelt pressed a ceremonial button that officially launched WLW's 500-kilowatt signal. As the first station in the world to broadcast at this strength, WLW received repeated complaints from around the United States and Canada that it was overpowering other stations as far away as Toronto. In December 1934 WLW cut back to 50 kilowatts at night to mitigate the interference, and began construction of three 50 ft. tower antennas to be used to reduce signal strength towards Canada. With these three antennas in place, full-time broadcasting at 500 kilowatts resumed in early 1935. However, WLW was continuing to operate under special temporary authority that had to be renewed every six months, and each renewal brought complaints about interference and undue domination of the market by such a high-power station. The FCC was having second thoughts about permitting extremely wide-area broadcasting versus more locally oriented stations, and in 1938, the US Senate adopted the "Wheeler" resolution, expressing it to be the sense of that body that more stations with power in excess of 50 kilowatts are against the public interest. As a result, in 1939 the 500-kilowatt broadcast authorization was not renewed, bringing an end to the era of the AM radio superstation.Because of the impending war and the possible need for national broadcasting in an emergency, the W8XO experimental license for 500 kilowatts remained in effect until December 29, 1942. In 1962 the Crosley Broadcasting Corporation again applied for a permit to operate at 750 kilowatts, but the FCC denied the application.

Korean Demilitarized Zone 1953

In the Armistice Agreement of July 27, 1953, the DMZ was created as each side agreed to move their troops back 2,000 m (2,200 yards) from the front line, creating a buffer zone 4 km (2.5 mi) wide. The Military Demarcation Line (MDL) goes down the center of the DMZ and indicates exactly where the front was when the agreement was signed.

Longest Glide in History - Air Canada Flight 143

The Gimli Glider is the nickname of an Air Canada aircraft that was involved in an unusual aviation incident. On 23 July 1983, Air Canada Flight 143, a Boeing 767-233 jet, ran out of fuel at an altitude of 41,000 feet (12,000 m) MSL, about halfway through its flight originating in Montreal from Ottawa to Edmonton. The crew was able to glide the aircraft safely to an emergency landing at Gimli Industrial Park Airport, a former Royal Canadian Air Force base in Gimli, Manitoba. The subsequent investigation revealed company failures and a chain of human errors that combined to defeat built-in safeguards. Fuel loading was miscalculated due to a misunderstanding of the recently adopted metric system which replaced the imperial system.

Versailles Indiana state park

Photo by: Jack Demaree
Versailles is an Indiana state park, near the town of Versailles, Indiana. The land was given by the National Park Service for use as a state park to Indiana's Department of Conservation in 1943.In the early 20th century, the area was farmland. In the 1930s, the National Park Service acquired the land, and hired the CCC to improve the land into a Recreational Demonstration Area. The 230-acre Versailles Lake was formed in 1954 when a dam was built across Laughery Creak . It is a recreation area, featuring fishing and boating on Versailles Lake and Laughery Creek. A covered bridge, the Busching covered bridge, crosses the creek. This Howe truss bridge was constructed in 1885, is 176 feet long, and although within the state park, Ripley county owns it. A group camp, originally constructed by the CCC, is available for use as well. Swimming isn't allowed in Versailles Lake, but a 25 meter pool is available.

Versailles Court House Anex

Click to enlarge
While taking the last photos of the Court House Anex the Sheriff sneaked up behind me to ask, "why are you taking photos of the Anex"? after I explained he said I did not look like a mad bomber and bid me good day. At any rate the Anex looks to be complete now. If there are no more drastic changes there will be no more photos. I got a kick out of recording the progress of the building project from beginning to end. I hope a few people liked seeing it too.

Moon of Neptune

Mark Showalter of the SETI Institute discovered S/2004 N 1 in July 2013 when examining Hubble Space Telescope (HST) images of Neptune's ring arcs from 2009 using a technique similar to panning to compensate for orbital motion. On 1 July 2013, after deciding "on a whim" to expand the search area to radii well beyond the rings, he found the "fairly obvious dot" that represented the new moon.  He then found the satellite in other archival HST images going back to 2004. Voyager 2, which had observed all of Neptune's other inner satellites, did not detect the moon during its 1989 flyby, due to its dimness.[4] Given that the discovery images have long been available to the public, the moon could have been found by anyone. S/2004 N 1 is the fourteenth known moon of Neptune, and the first Neptunian moon discovery to be announced
since September 2003.

The Manhattan Project

The Manhattan Project was a research and development project that produced the first atomic bombs during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. It began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (the equivalent of about $26 billion now). Although it operated under a tight blanket of security, it was penetrated by Soviet atomic spies. The first device ever detonated was an implosion-type nuclear weapon in the Trinity test (pictured), conducted at New Mexico's Alamogordo Bombing and Gunnery Range on 16 July 1945. Project personnel participated in the Alsos Mission in Europe, and in the bombing of Hiroshima and Nagasaki. After the war the Manhattan Project conducted weapons testing in Operation Crossroads, developed new weapons, established the network of national laboratories, supported medical research into radiology, and laid the foundations for a nuclear navy. It was replaced by the Atomic Energy Commission and the Armed Forces Special Weapons Project in 1947

Akutan Zero

Click to enlarge
The Akutan Zero, also known as Koga's Zero and the Aleutian Zero, was a type 0 model 21 Mitsubishi A6M Zero Japanese fighter plane that crash-landed on Akutan Island, Alaska Territory, during World War II. It was captured intact by the Americans in July 1942 and became the first flyable Zero acquired by the United States during the war. It was repaired and flown by American test pilots. As a result of information gained from these tests, American tacticians were able to devise ways to defeat the Zero, which was the Imperial Japanese Navy's primary fighter plane throughout the war.
