Ak-Sar-Ben Amateur Radio Club
Although there is anecdotal evidence of an amateur radio club in Omaha prior to World War II, The Ak-Sar-Ben Amateur Radio Club (AARC), as it exists today, was started in 1945 and has been affiliated with the American Radio Relay League (ARRL) since that time. The club is not affiliated with The Knights of Ak-Sar-Ben. The AARC has members involved in nearly every aspect of ham radio from DXing (distant station) to digital communications such as packet Radio and D-STAR to high-speed multimedia radio (HSMM). The membership ranges from new hams just starting their amateur radio "career" to seasoned hams willing to share their knowledge. The AARC holds monthly meetings on the second Friday of each month. Meetings are held at the Heartland Chapterhouse of the American Red Cross 2912 S 80th Ave, in Omaha. Members also meet "on the air" on Monday evenings at 9:00 p.m. on the KØUSA 2-meter repeater on 146.940(-) MHz. The AARC supports the Amateur Radio Emergency Services ( ...

Skywarn
Skywarn (sometimes stylized as SKYWARN) is a program of the National Weather Service (NWS). Its mission is to collect reports of localized severe weather in the United States. These reports are used to aid forecasters in issuing and verifying severe weather watches and warnings and to improve the forecasting and warning processes and the tools used to collect meteorological data. Reports are also used by local emergency managers and public safety organizations. Skywarn consists of a network of severe storm spotters who observe weather conditions and make reports of severe weather to their local NWS offices. These spotters are regularly trained by personnel from the local NWS offices. In many areas, classes are conducted each spring in advance of the coming severe weather season. Many SKYWARN spotters use methods to communicate with one another during severe storm events. A notable example of this is through the use of amateur radio nets, which is still an important method since s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio Emergency Service
In the United States and Canada, the Amateur Radio Emergency Service (ARES) is a corps of trained amateur radio operator volunteers organized to assist in public service and emergency communications. It is organized and sponsored by the American Radio Relay League and the Radio Amateurs of Canada. Communication failures have been a defining part of natural disasters and even some human-generated events such as the September 11 attacks that occurred in New York City in 2001. A lack of communication between firefighters at the World Trade Center contributed directly to the deaths of 300 of those firefighters. Amateur radio provides a means of communication "when all else fails". Historical operations Amateur radio operators belonging to ARES (and its predecessor, the Amateur Radio Emergency Corps) have responded to local and regional disasters since the 1930s, including the attacks of September 11, 2001, and the category 5 storms Hurricane Katrina and Hurricane Michael ...

Transmitter Hunting
Transmitter hunting (also known as T-hunting, fox hunting, bunny hunting, and bunny chasing), is an activity wherein participants use radio direction finding techniques to locate one or more radio transmitters hidden within a designated search area. This activity is most popular among amateur radio enthusiasts, and one organized sport variation is known as amateur radio direction finding. Types of transmitter hunts Transmitter hunting is pursued in several different popular formats. Many transmitter hunts are organized by local radio clubs, and may be conducted in conjunction with other events, such as a radio enthusiast convention or club meeting. Before each hunt, participants are informed of the frequency or frequencies on which the transmitters will be operating, and a set of boundaries that define a search area in which the transmitters will be located. Transmitter hunters use radio direction finding techniques to determine the likely direction and distance to the hidd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamfest
A Hamfest is a convention of amateur radio enthusiasts, often combining a trade show, flea market, and various other activities of interest to amateur radio operators (hams). In the United Kingdom the term rally is more commonly used for amateur radio conventions. "Hamfests" were noted as early as 1924 in the U.S. Activities Hamfests are events organized by amateur radio enthusiasts, for social gatherings and promotion of amateur radio hobby. Typically annual or semiannual events are held over a weekend, they can last from several hours to several days. Most feature a flea market where the attendees buy and sell radio and related equipment. The equipment found at a hamfest can vary significantly from the newest high-tech gear to used, refurbished, or even antique equipment. Haggling or bargaining is the most common means of sale. Equipment that was originally sold at great expense to commercial users (such as public safety agencies) can often be found at a fraction of the price. ...

Amateur Radio Licensing In The United States
In the United States, amateur radio licensing is governed by the Federal Communications Commission (FCC). Licenses to operate amateur stations for personal use are granted to individuals of any age once they demonstrate an understanding of both pertinent FCC regulations and knowledge of radio station operation and safety considerations. Applicants as young as five years old have passed examinations and were granted licenses. Operator licenses are divided into different classes, each of which corresponds to an increasing degree of knowledge and corresponding privileges. Over the years, the details of the classes have changed significantly, leading to the current system of three open classes and three grandfathered (but closed to new applicants) classes. Current license classes Amateur radio licenses in the United States are issued and renewed by the Federal Communications Commission. In 2022 the FCC began charging a Congressionally-mandated $35 administrative fee. Private indiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Museum Ships Weekend
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Packet Reporting System
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data. APRS data is typically transmitted on a single shared frequency (depending on country) to be repeated locally by area relay stations (digipeaters) for widespread local consumption. In addition, all such data are typically ingested into the APRS Internet System (APRS-IS) via an Internet-connected receiver (IGate) and distributed globally for ubiquitous and immediate access. Data shared via radio or Internet are collected by all users and can be combined with external map data to build a shared live v ...

Packet Radio
In digital radio, packet radio is the application of packet switching techniques to digital radio communications. Packet radio uses a packet switching protocol as opposed to circuit switching or message switching protocols to transmit digital data via a radio communication link. Packet radio can be differentiated from other digital radio switching schemes by the following attributes: * Transmitted data is broken into packets, each of which contains a destination (and typically the source) address * A transmitted message may be broken into a sequence of packets before transmission, which are then re-assembled into the original message upon reception * Packets for multiple destinations can be transmitted on the same radio link in an asynchronous fashion * A packet may be addressed to all possible recipients rather than a specific one (broadcast) * A packet may be stored and subsequently forwarded towards its destination by a network node This is very similar to how packets of data ...

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.
