The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Black Hill (North Lanarkshire, Scotland) mast?

I wondered the same. There seems to be no power increase on the new multiplex. Thinking about it, it would make sense for the power increase to take place at stage two so as not to have one multiplex more powerful than the others. Does anyone know?

Does anyone know the detailed schedule for the switchover. Clearly, the ending of analogue television transmissions in Scotland will be a historic occasion requiring to be marked with appropriate solemnity. Will the switch-off occur exactly at midnight? Will there be on-screen messages in advance? Will there be a formal close-down? Will the First Minister be giving a speech? Or will it be Billy Connolly? When should the whisky be opened?

Cannot receive any BBC channels via free view box since switchover (Sat 12 June). Tried new installation several times to no avail. other channels missing include the most popular ones eg yeserday; film 4 etc.

Can anyone suggest a fix?

ALL: A common problem is that, if signal levels were already on the high side before switchover, the new signal levels are too high and cause distortion. Some boxes will not be able to read the distorted signal level properly and report a lower signal level. You will often get picture and sound break-up and in the worst cases the multiplex will not be decodable.

If you have a booster or amplifier, you should remove it or turn it down. In some cases you may have fitted, or had fitted, a new aerial with too much gain - in this case, add an attenuator. If you're using a communal aerial, your landlord or agent should be ensuring that the levels entering your property are appropriate.

The new multiplex is definitely running at the final power level - if it were not, the relays would not be able to receive it in order to retransmit it.

Another common problem is old onDigital/ITV Digital or early Freeview equipment that cannot handle the 8K mode used after switchover. Check if it's on the list at . It also might not be able to handle the larger Network Information Table in use since 2008 - see . These lists are not complete, there may be other affected equipment not on them.

The extra channels in the 800 range mean that Humax PVRs will not record any programs o the channels with the correct number for the identical channel. Retuning as suggested by Humax for similar problem last year seems not to work. The workaound is to leave the box on at the time you want to record and it then seems to record but not in standby. Hope it will go away after 22 June when 800+ channels disappear

I have the HD version of the Humax box, which may work differently. However, what I did was to start an automatic rescan then immediately abort it. This left me with no channels at all. I then did a manual scan for each of the six Blackhill multiplexes (see top of page for details and remembemr to use the old numbers except for BBC-A which is the only multiplex to have moved). This seems to have worked perfectly. (If you have HD you need to change to DBV-T2 for channel 59 only.).

Bigdave: You get channel in the 800 range when you have failed to clear out the channel list before rescanning.

Briantist: Would you not get the same problem if you receive multiple incidences of the same station during the scan? I seemed to BBC1 three times.

Scott, what you say is true. one solution for this is to perform a factory reset or first time installation with no aerial connected so you clear the channel list. then manually tune only the frequencies from your local transmitter.

Matt: Actually that is effectively what I did with my Humax box. I started the automatic scan then aborted it, leaving no stations at all. I then manually scanned each of the six multiplexes. Only problem was that the HD multiplex showed nothing, until I realised that the default setting was DVB-T and had to be changed to DVB-T2. Having said all that, I was speaking to a colleague on the train home and I asked him if he had picked up multiple transmitters and how did he go about selecting the correct one. He had no idea what I was on about and said that he had followed the instructions and carried out a full scan. How many people, I wonder, will now be left with their equipment tuned to a transmitter that is not the strongest signal? I have to say that until this all started I knew next to nothing about digital television, main transmitters, relays etc so this has been an interesting learning experience and diversion into a completely new field. I am now getting quite enthusiastic!
