Nigel Webber:

The frequencies used have indeed changed, enter your post code into the Digital UK Coverage Checker at…ker. That will list the transmitters available in your area, give an indication of expected reception and show the channel numbers for all the available services.

We contributors know this website is not current but the owner is the only person alloed to make any changes - but he is not available at present.

I receive Freeview reception from the Blackhill Transmitter in Central Scotland via a wideband high gain TV aerial. I have retuned my TV after the 5th September 2018, but can no longer receive channels such as BBC NEWS 24 HD and other channels that were on the CH32 COM7 multiplex. Looking at the website here, it appears that COM 7 on CH32 and COM 8 on CH35 are not broadcasting after September 2018 and this seems to be confirmed in that I am now receiving zero signal strength on these channels. So where has BBC News 24 HD gone?

Two questions about the September/October 2018 frequency changes at Black Hill.

1. COM7 and COM8 are now on channels 55 and 56, which are slap bang in the middle of the 700 MHz range. How does this help to clear the 700 MHz range for 5g?

2. Craigkelly is also transmitting COM7 and COM8 on channels 55 and 56. Isn't this asking for trouble? I always understood that adjacent transmitters should use different frequencies to avoid interference. Otherwise why not use the same nine channels everywhere?

COM7 and COM8 are temporary services and are expected to cease around 2022 when more of the multiplexes are broadcast using the DVB-T2 coding scheme which can carry more data. That cannot be done until most receivers are able to handle that form of coding, but there are still too many older Freeview TVs that cannot, only those marked as Freeview HD can.

All 30 of the main transmitters that are carrying COM7 and COM8 will be using channels 55 and 56 - it's known as a single frequency network and does not cause any known problems. They don't use that scheme for all channels as the programme content differs across the country allowing regional news for example. COM7 and COM8 only carry services that are the same right across the UK.

My area is served by Blackhill, but for some reason today Ive lost all channels that were COM 7 and COM 8 now 55 and 56.
