I managed to get a Muzak receiver into install mode. This is one of the
newer digital receivers - not the analog FM-FM receivers. Anyway, Muzak MPEG
"lives" on AMC1. The carrier freq. listed in the receiver is 12144.50 Mhz.
The sample rate is 27.647 Mbps, FEC is 3/4, and Tag is set to 15. Is it
possible to use one of the FTA receivers to listen to this - personal use,
not theft for a commercial environment? The specs for the Muzak receiver are
as follows:
