62. QT - Changes To Coastal Radio Communication Services While a 27 Mhz marine radio has proven a more cost effective form of marine communication, VHF marine radio offers both recreational and commercial operators http://www.transport.qld.gov.au/qt/maritime.nsf/index/changes_radio

From 1 July 2002, Australian States and Territories will become responsible for monitoring marine radio distress services currently provided through the Telstra Coast Radio Station Network. From this date, the Telstra Coast Radio Station Network will close. Voice monitoring of MF, HF and VHF Channel 16 'distress and calling' frequencies from these stations will end and the broadcast of Safety Information (MSI) via HF voice will also be discontinued. The Queensland Government will provide services that will be available to all commercial and recreational vessels that operate in Queensland waters. The following information details the replacement services for HF and VHF radio and how it will affect those in the Queensland boating community. Replacement Services These replacement services apply to all commercial and recreational vessels operating in offshore, inshore or enclosed waters within Queensland. It should be noted that VHF replacement services apply ONLY to the areas which were previously covered by the Telstra Coast Stations, not coastal areas outside that coverage. Coastal areas outside this coverage will remain serviced by Limited Coast Stations operated by volunteer marine rescue groups monitoring frequencies on VHF, 27 Mhz and in some cases HF marine radio. These are not 24 hour manned stations nor do they monitor distress frequencies 24 hours.

63. Marine Radio Communication SHIP RADIO STATIONS. Depending on the size, purpose, or destination of a ship, itsradio station must meet certain requirements established by law or treaty. http://www.sailingcenter.com/radio.html

SHIP RADIO STATIONS The Telecommunications Act of 1996, which became law on February 8, 1996, brought about fundamental changes in the licensing of ship radio stations. This on-line version of WTB Fact Sheet #14, "SHIP RADIO STATIONS," contains information on radios that may be used aboard a ship, which ship radio stations must be licensed by the FCC, and how to use your marine VHF radio. TOPICS I. General Information About the Service II. Do I need a ship radio station license? III. Do I need a restricted radiotelephone operator permit? IV. How to get a license (if you need one) ... VI. FCC information (Forms, Fees, Rules) GENERAL INFORMATION A shipboard radio station includes all the transmitting and receiving equipment installed aboard a ship for communications afloat. Depending on the size, purpose, or destination of a ship, its radio station must meet certain requirements established by law or treaty. For example, large passenger or cargo ships that travel on the open sea are required by the Communications Act and by international agreements to be equipped with a radio station for long distance radio communications. Passenger ships that travel along the coast must be able to communicate at shorter range with coast stations. These are examples of "compulsory ships" because they are required by treaty or statute to be equipped with specified telecommunications equipment. Smaller ships used for recreation (e.g., sailing, diving, fishing, water skiing) are not required to have radio stations installed but they may be so equipped by choice. These ships are known as "voluntary ships" because they are not required by treaty or statute to carry a radio.

64. Radio Communication MURS radios are available yet you can use any Ham or business radio as long as unitsin all of my cars because they have an even wider range for communication. http://www.4x4abc.com/DV/02/radio.html

on What I recommend for communication between cars Good example of an inexpensive but powerful UHF/VHF radio - the Alinco DJ 196/196 I have been dealing with a Nevada radio shop for the last 15 years and they have been extremely helpful in any respect. Radio World or call 702-294 2666 ask for Dave While driving is very convenient to be able to talk from car to car. It is not a trip reqirement, for you to have your own radio. I will be able to loan out two handheld radios with additional magnet mount antennas. One of the recipients will have to drive as last vehicle in the convoy as "sweep" - reliable feedback from the rear is always important. If you decide to get your own radio I recommend a handheld 2 meter radio with business or MURS frequencies. An external antenna is not necessary but will extend the covered area dramatically. I have experimented over the years with different radio systems. Here is why I decided for 2 meter VHF/UHF: CB radios and the new Talkabout radios are really inexpensive but CB has such poor audio quality and bad reach (you can hear a trucker in Alabama but not the car 2 miles in front of you) and Talkabout has only a maximum reach of 3/4 mile at best (even though advertising promises you about 3 miles). Advantage of CB and Talkabout is that you don't need a license to operate those radios. High power Talkabouts are on the market but they require a license. Other systems with better sound quality and much better coverage (up to 50 miles) require a license as well - like Ham radio (below 148 MHz) and business band radios (above 148 MHz). - but who would want to get a license (including passing a test) for occasional use of a radio for safety and convenience reasons?

USAID Finances Life-Saving Radio Communication System Jinotega, Nicaragua— Yader Jose Garcia, a month-and-a half-year-old infant, lay in a hospital crib, struggling to breathe, while his mother unwaveringly held a vaporizer to his tiny face to help him. Doctors report that Yader, suffering from pneumonia, is now stable and recovering. If this had happened to a child a few months ago, the child probably wouldn’t have been able to get to a hospital and would have died. “They would have died, if we didn’t have the radio,” said nurse Zeledon, unequivocally. The radio installed in Los Alpes is part of a communication system, financed by USAID, that will provide a vital life-saving link between distant, outlying, health posts and municipal hospitals and ambulances. USAID, through the PROSALUD project, purchased 218 stationary and mobile radios, six repeaters and 40 solar panels at a cost of $300,000. This system, when fully operational, will permit rapid, reliable and permanent communication between all of the health centers, hospitals and ambulances in three departments that were heavily affected by Hurricane Mitch. The system will also link into the larger Ministry of Health communication network providing coverage to 77 percent of the country.

After the course the student will have knowledge about typical radio communication systems and environments, impact of radio channel fading on information transmission, fading countermeasures and their performance, radio noise and equipment impairments, radio link budget and system planning. The main goal is to provide information for radio link budget calculations in radio link and network planning, so that the student is able to choose system solutions, which will guarantee that the radio communication system will fulfil given specifications. The radio link budget is a simple instrument for this purpose, but the determination of the gains and losses in the different terms of the budget will require profound knowledge of the performance of the different transmission methods. The application of it to system planning requires understanding of the interactions between the used transmission methods and algorithms.

MUSEUM "WAALSDORP" Radio Communication Many forms of information transmission today are based on radio i.e. the use of electromagnetic waves. The preceding history since the middle of 18 th century comprises the observations by a great number of physicists investigating the phenomena of electricity and magnetism and their search for a fitting theoretical explanation. Based on this work Maxwell in 1864 postulated the relation between electric and magnetic field expressed in a new mathematical form. He introduced the subsequently much debated concept of "displacement current" for a non closed circuit and derived a wave equation in free space with light-like properties. Herz proved from 1888 the validity of Maxwell’s theory and discovered the advantage of tuning reception to transmission frequency. Marconi was the experimenter who foresaw the practical application for message transmission, in particular for ships at sea. He started experiments from 1895 onwards over increasing distances until in 1901 he successfully bridged the Atlantic from England. It is astonishing to realise this happened barely one century ago.

PROPERTY RIGHTS IN RADIO COMMUNICATION: THE KEY TO THE REFORM OF TELECOMMUNICATIONS REGULATION by Milton Mueller Milton Mueller is an associate policy analyst with the Cato Institute, currently working on a book on telecommunica- tions policy Executive Summary The Communications Act of 1934 subjected the telecommu- nications industry to a degree of central planning unprece- dented in the United States. The recent trend toward deregu- lation reflects an almost universal belief that this experi- ment in central planning was a failure. Nevertheless, all attempts at reform, even those promulgated in the name of deregulation, have left the backbone of federal regulation untouched: centralized allocation of the frequency spectrum. The Communications Act, like the Federal Radio Act that preceded it, claims the "airwaves" as the property of "the public," forbidding private ownership and market exchanges of radio frequencies. This claim of public ownership has given rise to a centralized system of licensing, which provides the legal and technical basis for many of the FCC's other rules and regulations.

The applications that we will consider are CntToLedsAndRfm and RfmToLeds CntToLedsAndRfm is a variant of Blink that outputs the current counter value to multiple output interfaces: both the LEDs, and the radio communication stack. RfmToLeds receives data from the radio and displays it on the LEDs. Programming one mote with CntToLedsAndRfm will cause it to transmit its counter value over the radio; programming another with RfmToLeds causes it to display the received counter on its LEDs - your first distributed application! The CntToRfmAndLeds Application Look at CntToRfmAndLeds.nc . Note that this application only consists of a configuration; all of the component modules are located in libraries!
