Introduction

A service providing exchange of data between ships or oil rigs and coast stations could be provided in the MF, HF and VHF bands allocated to the maritime mobile service as an extension to existing services. This report details the results of trials conducted in the United Kingdom in providing medium speed (1200/2400 bit/s) data links using MF and VHF frequencies and of tests conducted in the German Democratic Republic carried out at a speed of 1200 bit/s on HF frequencies. Further tests will be conducted at speeds in the range of 300 to 2400 bit/s.
