Sea 222 Operator's Manual
I SEA 222 OPERATOR'S MANUAL Featuring a unique "softouch" keypad, the SEA 222 is as easy to operate as a microwave oven. Just follow the directions in this booklet. The "brain" of the SEA 222 is divided into two parts: 1. 290 factory programmed frequency pairs selectable by channel number from EPROM memory. 2. 100 channels of "scratch pad" memory for front panel programming and recall (Note: 10 of these channels are "EMERGENCY" channels). When operating your SEA 222 please note: 1. Any two-digit key stroke followed by "enter" will recall user-programmed channels 10-99; 2. Any 3 and 4-digit key stroke followed by "enter" recalls factory -pro grammed channels. - ---- - - A UNIT OF DATAMARINE INTERNATIONAL, INC. I ( ( FRONT PANEL CONTROLS: DISPLAY: The eight-digit alphanumeric display provides the operator with frequency and channel data. 4 x 4 KEYPAD 16 keys allow the operator to communicate with the computer which controls radio functions. For simple operation, an "operator friendly" software package is used in conjunction with the display. All of the keys are listed below. ENT Enters previously keyed data into the computer. Number Keys Keys numbered 0 through 9 enter required numerical data into the computer. (Arrows) These keypads permit receiver tuning up or down in 100 Hz ..... steps. CH/FR Allows the operator to display either channel number or the frequency of operation. Example: pressing this key when the display reads "CHAN 801" causes the display to indicate the receiver operating frequency 'assigned to channel number 801 (8718.9 KHz).

DESCRIPTORS *Communication (Thought Transfer); Educational Innovation; *Educational Radio; Educational' Technology; Elementary Secondary Education; Interdisciplinary Approach; Language Arts; Self Esteem; *Student Motivation; ''Teaching Methods; *Vocational Education IDENTIFIERS *Ham Radio ABSTRACT Amateur radio is a technology and activity that offers great potential when integrated into academic or vocational curricula. Programs with electrical, electronics, and electromechanical content can benefit from the use of amateur radio, and can also enhance language and communications skills. The biggest value of amateur radio may lie in its ability to enhance a student's motivation and self-esteem. In addition to its specific vocational and technical applications, amateur radio can assist in teaching basic skills and in reducing the isolation of students and teachers as it promotes interdisciplinary education and cultural awareness. Amateur radio is distinctly different from citizens band, as it is a noncommercial service. Ham operators do not need an electronics background, although technical knowledge and skills are helpful. Several examples of the educational use of amateur radio illustrate its potential for academic and vocational education. -

The International Telecommunication Union (ITU) has set up a framework in which the demands for radio spectrum from the State of Ghana are balanced with the interests of different radio service users to produce a planned radio environment incorporating interference-free, effective and efficient radio spectrum use. Subpart 5 contains information on the assignment planning of individual aeronautical radio stations operating or planned to operate in different frequency bands. -

A Simultaneous Radiotelephone and Visual Range Beacon for the Airways
RP341 A SIMULTANEOUS RADIOTELEPHONE AND VISUAL RANGE BEACON FOR THE AIRWAYS By F. G. Kear and G. H. Wintermute ABSTRACT Increased use of the airway radio services by transport operators has resulted in a demand for continuous range-beacon service. At the same time the weather broadcast information has increased in importance and the interruptions to the beacon service have become more frequent. To eliminate difficulties arising from this conflict a transmitting system has been developed which provides simul- taneous transmission of visual range-beacon and radiotelephone signals. This system is designed to employ existing equipment so far as possible. By combining two transmitting sets into one the cost of buildings and antenna equipment is reduced. Continuous check on the operation of both systems can be obtained with less personnel than required at present. The transmitting set consists of a 2-kw. radiotelephone transmitter operating into a nondirective antenna system and an additional set of amplifier branches supplying power through a goniometer into two loop antennas. The two antenna systems are symmetrically disposed with respect to each other, and coupling effects are balanced out to prevent distortion of the space pattern. The phase of the currents in the different antenna systems is controlled by a phase shift unit and means for checking the adjustment of this phase relationship continuously is provided. The equipment on the airplane to receive this service is changed only by the addition of a small filter unit which keeps the low-frequency reed voltages from reaching the head telephones and the voice frequencies from the reed indicator. -

Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -
