Only 4 - some early TV's had many more station
buttons. It obviously never would have worked very
well.
A reason to switch off the analogue
transmitters
sooner ? Perhaps it will last as long as metrification!

Breakup...
Many people had the same problem with CH5.
35
&
37 were assigned to channel 5 for large parts of the country and
many people needed a wideband aerial to get CH5.
The basic
problems
are... 1. The channels spacing were only ever designed to accomodate 4
channels. 2. The UK is physically too small to have the number of
transmitters it does.
Most of the time the signals will keep
within
the defined boundaries of the transmitter footprint, but in the summer,
atmospheric conditions make the signals travel much further into other
areas using the same frequencies. Now the 7 extra channels are needed
everywhere (CH5 + 6 Muxes) anything being received on those frequencies
will mess up reception.
Because of the above problems with skip,
Channel 5 is often at a much lower power than Ch 1-4. Digital can work
with
much lower levels but if it happens to get swamped by a strong analogue
signal you lose digital.
