Ref OTFORD TV transmitter digital switchover:
Q1: Why is the power output of this transmitter being reduced at digital switchover? I live on the A225 with a clear view of this transmitter and regardless of using a high gain external aerial, or portable internal aerial, receive a poor analog signal. I am worried about reception after digital switchover (My TVs are analog/digital - freeview so on in April I will find out if I have wasted my money)
Q2: Why will only three digital multiplexes be available when there are currently four analog channels? (As this will limit the number of freeview channels available)

Chris:

1. The power of most transmitters is being reduced in the same way (-7dB). This amounts to the same coverage on digital as analogue.

2. Each multiplex carries a number of channels. From Otford there will be three muxes: one for BBC channels, one for ITV/C4/E4/More4/C5 and one for HD channels.

The reason that Otford won't carry alot of the other channels such as Dave and Yesterday is explained here:

As for your analogue picture being poor; it could be that your TV has tuned to the Crystal Palace signal which is predicted by the Digital UK website (even though your aerial points at Otford). (DN31NJ)
