System Expansion For WLO Radio

Mobile Marine Radio, Inc., owners and operators of coastal station WLO Radio, North America, one of the largest public coast stations in the U.S., and one of the world's largest coast stations offering fully automatic Radiotelex, has awarded to Radio-Holland USA, BV, an expansion contract of 12 automatic channels to their previously upgraded and operational 16-channel fully automatic RTX system.

WLO Radio not only pioneered Radiotelex services in the U.S. over 13 years ago and was the first station to offer this type of service, they are also the only USA coast station to offer completely automatic end-to-end telex-at-sea communications.

Through Radio-Holland in Houston, WLO's modernization program started in 1985 with the initial purchase of Thrane & Thrane's eightchannel semiautomatic direct shipto- shore system, with free signalling generation.

The RTX system was upgraded in 1986 with eight more channels, the new CCIR Rec. 625 (as well as 476-3 for full backward compatibility) and the TT-1000 host computer to provide via a sophisticated data base, automatic store-and-forward, shore-to-ship and ship-to-shore traffic.

With the delivery of the 12-channel expansion, WLO's system configuration consists of: 28 TT-1585 Radiotelex modems, seven channel processors (the traffic cop allowing for simultaneous call capabilities to/ from land-line subscribers), seven manual assist positions (MAPs), seven log printers (for automatic logging of traffic status and toll- ticketing), and the TT-1000 communications processor and associated peripherals.

Thrane & Thrane automatic Telex-Over-Radio RTX equipment is now installed at six fully automatic and six semiautomatic Radiotelex stations.
