On November 13 and 14, 2021 the Greek Amateur Radio Team DX Plus will inaugurate a new annual activity weekend which remembers the Coast Radio Station services which were once found all over the world, a service which traced their history right back to the founding fathers of radio and most of which are no longer active.
The Greek team will be active for 48 hours with the callsign SX1SVA, remembering the Greek Coast Radio Station Athinai Radio, callsign SVA, and the team will be staffed by former SVA Radio Officers operating from one of SVA’s former sites.
The DX Plus team invite Amateur Radio Operators and Amateur Radio Clubs to join them in this new initiative and set up special event station representing the former Coast Radio Stations close to them. Clubs and individuals able to participate in this event are requested to indicate their activity to sv1rp@yahoo.com.
The aim of the event is to remember the memory of these former stations by “talking” to each other, other participating stations and other Radio Amateurs, as many stations as possible, but the event is also aimed at Short Wave Listeners and wireless operators who are QSL card collectors. The event will run on the HF bands using CW.
Further information about this new event can be found the event website. This page will be updated as more information becomes available.
Coast Radio Stations can trace their histories right back to the founding fathers of radio, such as Guglielmo Marconi. Their operations continued for almost 100 years with technology changing over the years from Morse Code with spark transmissions then CW using first very long wave transmissions then medium frequency and eventually spanning the world using high frequency transmissions. Telephony was added using first Amplitude Modulation (double sideband) then single sideband. Very High Frequency stations then came in to use using frequency modulated telephony while on the medium and high frequencies radio teletype came in to use using the SiTOR system.
Politics had often followed the existence of the maritime radio service at sea, with ship owners not happy at the cost of having to carry Radio Officers on board, but Safety of Life at Sea was always paramount and always won out. Technology, however, continued developing both on shore, in terrestrial radio and through satellite radio systems.
Technology and ongoing political pressures brought about the Global Maritime Distress and Safety System, a system based on a combination of digital terrestrial radio and satellite communications. Supposedly, but debatably, easier to use, this gave the excuse to introduce GMDSS to the Safety of Life at Sea regulations with a period of change over tot he new system and a defined date for ceasing the former non-digital systems.
At the same time, on shore mobile communications expanded and the development of digital cellular telephone systems, including the establishment of more and more coastal based cells, provided the ship owner with a simpler, cheaper and more secure method of making short range telephone calls, dramatically reducing the traffic and profitability of the maritime coast radio station service.
The age of the professional Radio Officer at sea and on shore was numbered. The day of the efficient but expensive Coast Radio Stations was coming to an end.
