Yes Craig, I do understand the concept. My remarks were directed to the "pure" SFN installations being tested in at least one U.S. market. A Main TX and repeater/translator "systems" seems a more practical solution in many areas. Regarding my area: the Santa Barbara Mkt. is somewhat a-typical, spanning the coast for about 150 miles and crisscrossed with very significant mountain ranges. The network VHF transmitters are scattered from the extreme North end to the extreme south end of the market. There are very few population centers that fully receive all three stations, while many receive none or just one. Covering this market with OTA UHF DTV would require a large mix of repeaters and translators*. However, that is an unlikely scenario given that Cable/DBS service has major penetration - obviously! * Many population centers have partial coverage with relatively strong signals from a main transmitter on a high mountain, while the remainder of the city is blocked. The distance between the repeater/Transmitter are enough to create receiver EQ difficulties and could require a translator. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
