The Reed's VHF DSC Handbook is a user-friendly guide that gets marine VHF radio users quickly up to speed with both the analogue and digital functions on the radio. Sue Fletcher's straightforward explanations and tips describe the leisure craft VHF DSC radio system in detail and its place within GMDSS. Since it was first published it has become the standard work on the subject. Updated to take into account new developments and procedures it provides: all the information required to pass the Short Range Certificate (SRC) - which is compulsory for anyone using a VHF DSC radio; radio procedure, channel allocation, VHF radio theory and more; a full explanation of GMDSS, including details on EPIRBs, SARTs and Navtex; an invaluable onboard reference. The rescue authorities and commercial maritime world now rely almost entirely on DSC for initial contact, so if you need help and want to be heard, a marine VHF DSC radio is essential. 'If you are looking for just one book to explain all marine VHF operating code and procedure, you need look no further...Packed with hints, tips and sound advice, it explains, in the clearest possible way, all one could wish to know about VHF, present and future.'
