[QUOTE="A nonymous, post: 459992, member: 240839"] The analogue channels are usually 20-25dB stronger than the Digital Muxs although they do have a tendency to be at leat 3-4 channel frequencies away from the digital stuff. The problems with Digital is that its not all about out and out power as it is with analogue, its all to do with the quality of the signal. As long as the Digital output is around 35-40dB it can be launched onto a communal TV system without too many problems :o At work we normally try to launch the analogue stuff at about 80dB and the Digital muxes at about 55-60dB The biggest problem we usually have is co-channel interference from one of the digital muxs effecting analogue channel 5, but only off one transmitter. :-beer Nano [/QUOTE]
