If it was a ssb sw feeder, how do they keep the received (at the >relay site) audio quality high enough to re-transmit? Well VOA use a system whereby they transmit one feed on one carrier and another feed on another (although I would imagine that this practice is becoming less common as satellite feeds become cheaper). Obviously an international broadcaster is going to have equipment capable of receiving ssb signals in such a manner that they ARE good enough for re-broadcast. Perhaps a lot of audio processing is done at the receiving end ? Radio Nederland use to ship out tapes of their programs to their relay stations (although items such as news would have to be relayed from SW). They too now use satellite. + Computing Science Dept, University of Newcastle | All opinions expressed + + Newcastle upon Tyne, UK, NE1 7RU (091 265 2486) | are mine and mine alone! + + ARPA: C.Dennison@newcastle.ac.uk | Chris Dennison + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
