Rio Grande County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 11,539. The county seat is Del Norte. The county is named for the Rio Grande, which flows through the county.
Tropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to 500 kilometres (310 mi) and further depending on frequency of operation, equipment type, terrain, and climate factors. This method of propagation uses the tropospheric scatter phenomenon, where radio waves at UHF and SHF frequencies are randomly scattered as they pass through the upper layers of the troposphere. Radio signals are transmitted in a narrow beam aimed just above the horizon in the direction of the receiver station. As the signals pass through the troposphere, some of the energy is scattered back toward the Earth, allowing the receiver station to pick up the signal.
The Supreme Headquarters Allied Powers Europe (SHAPE) is the military headquarters of the North Atlantic Treaty Organization's (NATO) Allied Command Operations (ACO) that commands all NATO operations worldwide. SHAPE is situated in the village of Casteau, near Mons, Belgium.
The 9×19mm Parabellum is a rimless, tapered firearms cartridge.
A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver. It is an equation giving the received power from the transmitter power, after the attenuation of the transmitted signal due to propagation, as well as the antenna gains and feedline and other losses, and amplification of the signal in the receiver or any repeaters it passes through. A link budget is a design aid, calculated during the design of a communication system to determine the received power, to ensure that the information is received intelligibly with an adequate signal-to-noise ratio. Randomly varying channel gains such as fading are taken into account by adding some margin depending on the anticipated severity of its effects. The amount of margin required can be reduced by the use of mitigating techniques such as antenna diversity or multiple-input and multiple-output (MIMO).
The White Alice Communications System was a United States Air Force telecommunication network with 80 radio stations constructed in Alaska during the Cold War. It used tropospheric scatter for over-the-horizon links and microwave relay for shorter line-of-sight links. Sites were characterized by large parabolic, tropospheric scatter antennas as well as smaller microwave dishes for point-to-point links.
Yaesu FT-101 is a model line of modular amateur radio transceivers, built by the Yaesu Corporation in Japan during the 1970s and 1980s. FT-101 is a set that combines a solid state transmitter, receiver and a tube final amplifier. Its solid state features offer high-performance, low-current characteristics and its tube amplifier provides an almost mismatch-resistant transmitter and tuner stage. FT-101s were made with plug-in circuit boards that could be sent to the dealer or factory for replacement or repair. Until then, modular design was unprecedented in the amateur community. This also explains the fact why so many FT-101s are still in use today. The rig was sold worldwide as Yaesu FT-101 and in Europe as Yaesu FT-101 and as Sommerkamp FT-277. Because of its reliability it earned its nickname "the workhorse".
Electoral history of Herbert Hoover, who served as the 31st president of the United States (1929–1933) and 3rd United States Secretary of Commerce (1921–1928).
The Ekeberg Line is a 6.6-kilometre (4.1 mi) long light rail line of the Oslo Tramway which runs from Oslo Hospital to Ljabru in Oslo, Norway. Operated by lines 13 and 19, it serves the area of Nordstrand and the neighborhoods of Ekeberg, Jomfrubråten, Bekkelaget and Ljan. The line is operated by Oslo Sporvognsdrift using SL79 and SL95 trams on contract with Ruter. The line itself is owned by Sporveien. At Oslo Hospital, the line connects to the Bjørvika Line, which runs to the city center.
Electoral history of Ron Paul, Republican U.S. Representative from Texas, 1988 Libertarian Party Presidential nominee and candidate for the 2008 and 2012 Republican presidential nomination.
One human poll comprised the 1943 National Collegiate Athletic Association (NCAA) football rankings. Unlike most sports, college football's governing body, the NCAA, does not bestow a national championship, instead that title is bestowed by one or more different polling agencies. There are two main weekly polls that begin in the preseason—the AP Poll and the Coaches' Poll. The Coaches' Poll began operation in 1950; in addition, the AP Poll did not begin conducting preseason polls until that same year.
The North Atlantic Radio System (NARS) was a chain of 5 tropospheric scatter communication sites. It was an expansion of the former Distant Early Warning Line. NARS was built for the United States Air Force (USAF) by Western Electric (AT&T) and its sites were maintained under contract by ITT Federal Electric Corporation. All NARS stations were supervised and controlled by the USAF, by agreement with the Canadian and Danish Governments.
