The marine radio station
is the summary of apparatus, aerials and all equipments for communication between ships and shore. On the special sites from my favourite ships you can see complete listed radio equipment.It comprised from radio transmitter for medium, intermedium and short waves, between about 100 and 1500 watts output to Receiver, mostly all bands between LF and about 30 MHz.Transceiver for VHF, used in coastal areas and also during sea trips between ships and from ship to shore. Very important has been the life saving equipment i.e. emergency transmitter and receiver,powered by accumulators, automatic alarm keyer and automaticalarm receiver for medium and intermedium waves and last not least the life boat radio station. Later in the seventies the ships have been equipped with teleprinter (sometimes in a seperate room) and faksimile printers for weather charts. Furthermore the radio officers were responsible for readiness for actionof all radio navigation equipments on board, i.e. radars and direction finder. Alltogether it was a wide range of technical systems requiring good skilled persons for servicing. therefore we had a long and very good education as told on the special site.
The radio stations were situated according to the rules very close to the ships bridge, sometimes real radio "stalls", later fine bride working rooms. Until to the seventies the aerials had been mostly long-wire-aerials, sometimes double-L-aerials. Later came the mast-aerial, seen in the third foto left. The service hours on a ship radio station were according international regulations on a strict timetable in each sea region, formerly in GMT (greenwich mean time) now UTI (universal time international) and has been firstly not to send or receive messages, private telegrams or telephone speeches, more to listen on 500 kcs,the international safety and calling frequency . esides the radio officer had to receive continued weather reports, weather and nautical warnings and all other safety information concering ships safety.
