Radiotelegraphy

       Constanta Radio, actual C.N.R.N. Radionav S.A., has been issueing about the early ‘60, when they founded the radio station in the coastal Gate 4 Constanta port, built in collaboration with the British for Romania. Subsequently in 1973 and have performed the first two centers investments are constructed, one for transmission at Cumpana and one for reception Agigea.
       Experience that time consist of radio equipment for work in telegraphy and telephone and fully complies with the requirements of S.O.L.A.S. Initial fields of broadcasting antennas and transmitters of 7.5 and 15 KW liaise stable over the whole world's seas and oceans.
       Due to system implementation G.M.D.S.S. which introduced system NAVTEX and satellite communications, most coastal stations have abandoned traditional mode by telegraphy (A1A).
       "Constanta Radio" keeps this mode (A1A) working with power equipment smaller and further forwards storm notices, weather and navigational advice for Western Black Sea, in the area covered by the points of coordinates - latitude 43.5 N - 45.5 N and longitude 28E-2E.
       Storm notices and those for the safety of navigation are provided in an additional schedule upon arrival and after the first two periods of telegraphic silence (H +18, H +48). To make telegraphic transmissions "Constanta Radio" uses two transmitters SAILOR 500 W power installed Agigea Control Center and two multi-band receivers "SKANTI R8003" and "FURUNO RV107".
