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.
