S+AS Limited has a reputation for supplying a high quality system. Comprising known component parts, our complete systems are used as the heart of many digital satellite uplink networks. The complete station comprises an approved antenna system with mount and [typically] a two port Tx/Rx feed plus a 1+1 redundant SSPA and outdoor control box. IFL Coax and control cables feed to the indoor units. The IDU consists of a redundant pair of modems and the associated protection switch, plus the indoor SSPA control system.
The picture on the left, above, shows a typical Radio station uplink. The SF24 Eutelsat approved antenna system is mounted on the roof and is fitted with a 1+1 redundant 16Watt SSET 'S' series transceiver. The indoor unit comprised a 44U rack holding a two channel audio hub on a 1:8 protection switch. The whole station is controlled from a computer in the station managers office on the ground floor and transmits 2 digitally coded [Mpg layer II] audio channels one @ 256Kbps the other @ 192Kbps.
In this network, out in the field there are 36 receive only stations which supply a superior digitally encoded signal to the Radyne/Comstream ABR which in turn provides a very clean analogue signal to the FM transmitters. The station Manager has complete control over these remote stations supplying not only Audio but also data [for RDS] and independent, time or event trapped, contact closures for insertion of local advertising etc.
