Whats the difference between a UHF channel number and a Freeview channel number?
These are two totally different concepts. UHF channel numbers run from 21 to 68. Each channel can carry one transmission, which can be either an analogue television channel or a Freeview multiplex. In order to keep interference from adjacent transmitters to the minimum, a complicated arrangement of different UHF channels numbers is used for each transmitter. Freeview channel numbers are purely logical, in the sense of being virtual channels (but not in the sense of being in a sensible order). They are often referred to as LCN’s (logical channel numbers). Possible Freeview channel numbers run from 1 to 899, with numbers in the 800’s reserved for duplicate channels. I’m not sure if channel numbers in 900’s are possible or not. All other allocations of banks of channel numbers are arbitary and liable to change.
