Obviously, I've got more to learn about this. ![]() I'm still looking for this one. Nobody is broadcasting shortwave frequencies from satellites. (There are a few ham satellites with repeater outputs on the 10-meter band, if they haven't died by now.) Gene has a conventional TV channel on satellite, but in addition he and others are using the new technology which is taking the place of shortwave in affluent countries, MPEG broadcasting. Basically this is using the same multiplexing and modulation scheme as DBS but with no encryption, on the medium-power Ku-band satellites rather than the high-power DBS satellites. Just like DBS, you can pack a few video channels and a lot of audio channels onto one transponder. In the United States, you'll find two main types of things broadcast this way: foreign-language programming (Asian channels are particularly popular) and Protestant evangelism.
