USCGC Mackinaw (WAGB-83)
USCGC ''Mackinaw'' (WAGB-83) is a former Coast Guard icebreaker on exhibit as a museum ship at the Ice Breaker Mackinaw Maritime Museum in Mackinaw City, Michigan. The vessel has been known as the "Queen of the Great Lakes" and "The Largest Icebreaker on the Great Lakes"; the site states that "she was built ... during World War II to meet the heavy demands of war materials and transportation during the winter months". ''Mackinaw'' was both commissioned and homeported during active service in Cheboygan, Michigan. Due to her age and expensive upkeep, she was decommissioned and replaced with a smaller multipurpose vessel, , which was commissioned in Cheboygan the same day. The old ''Mackinaw'', LR number 6119534, moved under her own power on 21 June 2006 Cheboygan to a permanent berth at the dock on the eastern end of the old railroad dock; entry to the area is just south of the Shepler's Marine Service. Construction The ''Mackinaw'' (WAGB-83) was laid down on 20 March 194 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Lawrence Seaway
The St. Lawrence Seaway (french: la Voie Maritime du Saint-Laurent) is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes. The St. Lawrence River portion of the seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United States b ...

Global War On Terrorism Service Medal
The Global War on Terrorism Service Medal (GWOT-SM) is a military award of the United States Armed Forces which was created through Executive Order 13289 on 12 March 2003, by President George W. Bush. The medal recognizes those military service members who have supported operations to counter terrorism in the War on Terror from 11 September 2001, to a date yet to be determined. Previously awarded for the broadly defined awarding criterion of "support duty", the GWOT-SM is no longer a quasi-automatically awarded medal similar to the National Defense Service Medal (NDSM), whereas the GWOT-SM is awarded after thirty days of post-training active service. Effective September 11, 2022, it is now awarded to servicemembers only serving in the area of effect for approved campaigns related to the Global War on Terrorism. Background In September 2002, the U.S. Department of Defense sent a request to the U.S. Army Institute of Heraldry to provide a design for a Global War on Terrorism Se ...

National Defense Service Medal
The National Defense Service Medal (NDSM) is a service award of the United States Armed Forces established by President Dwight D. Eisenhower in 1953. It is awarded to every member of the US Armed Forces who has served during any one of four specified periods of armed conflict or national emergency from June 27, 1950 through the present. Combat or "in theater" service is not a requirement for the award. History The National Defense Service Medal (NDSM) was first intended to be a "blanket campaign medal" awarded to service members who served honorably during a designated time period of when a "national emergency" had been declared during a time of war or conflict. It may also be issued to active military members for any other period that the Secretary of Defense designates. To date, the NDSM has been awarded for four specific time periods, which roughly correspond to the Korean (1950-1954), Vietnam (1961-1974), Gulf (1990-1995), and the Global War on Terrorism (2001 to 2022). ...

World War II Victory Medal
The World War II Victory Medal is a service medal of the United States military which was established by an Act of Congress on 6 July 1945 (Public Law 135, 79th Congress) and promulgated by Section V, War Department Bulletin 12, 1945. The World War I Victory Medal is the corresponding medal from World War I. History The World War II Victory Medal was established by an Act of Congress on 6 July 1945 (Public Law 135, 79th Congress) and promulgated by Section V, War Department Bulletin 12, 1945. The medal was designed by Thomas H. Jones and approved by the Secretary of War on 5 February 1946. Consequently, it did not transition from a ribbon to a full medal until after World War II had ended. The World War II Victory Medal was first issued as a service ribbon, referred to as the “Victory Ribbon.” The Congressional authorization for the medal specified that it was to be awarded to any member of the United States military, including members of the armed forces of the Govern ...

American Campaign Medal
The American Campaign Medal is a military award of the United States Armed Forces which was first created on November 6, 1942, by issued by President Franklin D. Roosevelt. The medal was intended to recognize those military members who had performed military service in the American Theater of Operations during World War II. A similar medal, known as the American Defense Service Medal was awarded for active duty service before the United States' entry into World War II. History The American Campaign Medal was established per Executive Order 9265,6 November 1942, by President Franklin D. Roosevelt and announced in War Department Bulletin 56, 1942. The criteria were initially announced in Department of the Army (DA) Circular 1, dated 1 January 1943, so that the ribbon could be authorized prior to design of the medal. The criteria for the medal were announced in DA Circular 84, dated 25 March 1948 and subsequently published in Army Regulation 600–65, dated 22 September 1948. The ...

Field Day (amateur Radio)
Field Day is an annual amateur radio exercise, widely sponsored by IARU regions and member organizations, encouraging emergency communications preparedness among amateur radio operators. In the United States, it is typically the largest single emergency preparedness exercise in the country, with over 30,000 operators participating each year. Field Day is always the fourth full weekend of June, beginning at 18:00 UTC Saturday and running through 20:59 UTC Sunday. Since the first ARRL Field Day in 1933, radio amateurs throughout North America have practiced the rapid deployment of radio communications equipment in environments ranging from operations under tents in remote areas to operations inside Emergency Operations Centers (EOCs). Operations using emergency and alternative power sources are highly encouraged, since electricity and other public infrastructures are often among the first to fail during a natural disaster or severe weather. To determine the effectiveness o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Tone-Coded Squelch System
In telecommunications, Continuous Tone-Coded Squelch System or CTCSS is one type of in-band signaling that is used to reduce the annoyance of listening to other users on a shared two-way radio communication channel. (See squelch.) It is sometimes referred to as tone squelch. It does this by adding a low frequency audio tone to the voice. Where more than one group of users is on the same radio frequency (called ''co-channel users''), CTCSS circuitry mutes those users who are using a different CTCSS tone or no CTCSS. It is sometimes referred to as a sub-channel, but this is a misnomer because no additional channels are created. All users with different CTCSS tones on the same channel are still transmitting on the identical radio frequency, and their transmissions interfere with each other; however; the interference is masked under most conditions. The CTCSS feature also does not offer any security. A receiver with just a carrier or noise squelch does not suppress any sufficiently s ...

Straits Of Mackinac
The Straits of Mackinac ( ; french: Détroit de Mackinac) are the short waterways between the U.S. state of Michigan's Upper and Lower Peninsulas, traversed by the Mackinac Bridge. The main strait is wide with a maximum depth of , and connects two of the Great Lakes, Lake Michigan and Lake Huron. Hydrologically, the two connected lakes are one body of water, known as Lake Michigan–Huron. Historically, the native Odawa people called the region around the Straits Michilimackinac. The three islands forming the eastern edge of Straits of Mackinac include the two populated islands, the Bois Blanc and Mackinac, and one in between them that is uninhabited, the Round island. The Straits of Mackinac are major shipping lanes, providing passage for raw materials and finished goods and connecting, for instance, the iron mines of Minnesota to the steel mills of Gary, Indiana. Before the railroads reached Chicago from the east, most immigrants arrived in the Midwest and Great Plains by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...
