Brief Description The CMX7031/CMX7041 FI 1.5 is a full-function, half-duplex, audio, signalling and data processor IC. This makes it a suitable device for both the leisure radio markets (FRS, MURS, PMR446 and GMRS) and for professional radio products (PMR/LMR, Marine and Trunking) with or without signalling and data facilities. The device utilises CML’s proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image™: this is a data file that is uploaded during device initialisation and defines the device’s function and feature set. The Function Image™ can be loaded automatically from an external EEPROM or from a host µController over the built-in C-BUS serial interface. The device’s functions and features can be enhanced by subsequent Function Image™ releases, facilitating in-the-field upgrades. This document refers specifically to the features provided by Function Image™ 1.5. Continued… 2013 CML Microsystems Plc The Two-Way Radio Processor CMX7031/CMX7041 The CMX7031 features two on-chip RF synthesisers, with easy Rx/Tx frequency changeover, and programmable system clocks to minimise chip count in the final application. The CMX7041 is identical in functionality to the CMX7031 with the exception that the two on-chip RF Synthesisers have been deleted, which enables it to be supplied in a smaller package and with two extra GPIO pins. This document refers to both parts generically as the CMX7031, unless otherwise stated. When loaded with Function Image™ 1.5, both devices perform simultaneous processing of sub-audio and inband signalling and audio band processing (including frequency inversion scrambling, companding and pre- or de-emphasis). Other features include a complete MSK/FFSK modem for packetised or free-format data, a DSC modem, two auxiliary ADC channels with four selectable inputs and up to four auxiliary DAC interfaces (with an optional RAMDAC on the first DAC output, to facilitate transmitter power ramping). The device has flexible powersaving modes and is available in both LQFP and VQFN packages. Note that text shown in pale grey indicates features that will be supported in future versions of the device. This Datasheet is the first part of a two-part document comprising Datasheet and User Manual: the User Manual can be obtained by registering your interest in these products with your local CML representative. 2013 CML Microsystems Plc Page 2 D/7031/41_FI1.x/13 The Two-Way Radio Processor CMX7031/CMX7041 CONTENTS Section Page 1.

  • 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.

When using radio, there is no substitute for common sense. Clear speech assists reception and avoids the need for Every VKS-737 Network subscriber must be able to repetition or correction. Hold the microphone close to your mouth and talk across it (not into it). effectively speak on, and understand the operation of their radio. The following factors will assist in achieving successful transmission of messages:- To do this efficiently, requires knowledge of both Standard Radio Operating Procedures and Professional Radio Rhythm Operating Procedures! Ordinary conversation has a natural rhythm which needs to Most new subscribers are very nervous the first few times be preserved when speaking on radio.
