Using UHF channels C61 to C69? Time to retune

As from today, the whole of the "800MHz" band belongs to Three, EE, Vodafone and O2. If you are not a giant telecoms company, and are using still them for anything, now is probably a good time to stop.

Since 1964, the UHF band (channel 21 to channel 68) has been used exclusively for television services.

The main use, of course, has been over-the-air signals to bring five analogue (and latterly lots of extra digital) TV channels, but a secondary use has been for what is called "RF modulation".

In the days before SCART cables, and long before the not ubiquitous HDMI connections, if you wanted to get a signal from a device such as a video recorder, a games console, home computer or a satellite decoder to a TV set, the only option was to "modulate" it.

If you are still using a device with an RF modulator, you need to check that the channel allocated is not in the C61-C69 range. If it is, then you need to change it for two reasons: to stop an "illegal broadcast" interfering with 4G devices, and to stop 4G transmissions interrupting your video.

Who owns the 800MHz band? It's not you.

The most common devices are Sky Digital boxes produced from October 1998 to about 2010. See How do I change the RF output channel on a Sky Digibox? .

Please don't forget you will need to retune your TV as well as the RF modulator!

Hammy: It has moved to the local TV multiplex. If you can receive a local TV station on channel 7 or 8 then retune and Sony Crime Channel should reappear.

Receiving our Freeview from Stockland hill. We lack certain channels. BBC news hd being just one. Are we ever going to receive the full range of channels that are available on say the Mendip transmitter or are we doomed to receive a second rate service forever. Considering Freesat now

Alan Mapp:

There are no plans to add the COM7 or COM8 services to any more transmitters. When the reshuffle of channels to make room for the 5G services is completed, it is hoped that more DVB-T2 services will be available and that will make it possible for more multiplexes to be made available from more transmitters. So it looks as if patience is needed.
