The symbol shows the location of the Black Hill (North Lanarkshire, Scotland) transmitter which serves 940,000 homes. 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'm having some problems with Coms 7 and 8 at KA6 area. Can confirm atleast two different houses are missing all channels on those frequencies. I suspect this may be due to the higher than normal temperature right now. One households aerial is on the roof, the other in the loft. Loft one may not be optimally directed, but is good enough to pick up all other channels.

There has been some Tropospheric Ducting around affecting different parts of the UK at different times throughout the last few days and this may have been the cause of your issues. On the other hand, the Black Hill transmitter was listed last week for Planned Engineering with "Possible service interruptions" that work might still be ongoing even though the transmitter isn't listed this week!

But furthermore, coverage from Black Hill is very patchy is significant parts of the KA6 area and we'd need a Full postcode to see what the Freeveiw Detailed Coverage checker was giving for predicted reception at your location. Other multiplexes may seem ok but COMs 7&8 might not be predicted to be good.

Margaret Murphy:

Firstly don't retune under no signal conditions, it just clears all correct tuning.
Unfortunately the transmitter is currently listed for Planned Engineering with "Possible service Interruptions" so you will experience loss of signals maybe a few times.

The signals will return at various stages during the maintenance. IF you retuned when you had no signal, you will have to retune again once the signals have returned. You may have to do this several times if you don't get all channels back the first time, as all the multiplexes may not be back on at the same moment.

"Which Freeview channels does the Black Hill transmitter broadcast?"

This list is not up-to-date, e.g. the local LG mux broadcasts on C30 (456 MHz) not C51.

When some of the site is maintained it is confusing not to maintain all of it.

As per my post Sunday, 10 May 2020 on the previous page (83) of this transmitter section (but with COM8 omitted because of closure) -
Listing the correct UHF multiplex channels for Black Hill in the order PSB1-3, COMs4-7, Local -
They are C46, C43, C40, C41, C44, C47, C55, C30 (C meaning UHF channel).

I haven't checked every miniscule detail on this site, but AFAIK none of it is currently being maintained by the site owner who hasn't had time with all the changes resulting from the 700MHz clearance programme and broadcaster changes moving multiplexes etc. Even Engineering updates do not always appear, as the previous automated scanning of the BBC information doesn't work correctly due to changes on the BBC site, which made it even more difficult than before to obtain transmitter information manually. I for one have criticised the BBC, as have others, for this ridiculous change.

Updates to information are provided by the regular contributors in posts here usually in response to queries from posters, but sometimes when there are major changes. As already advised Platform management | Freeview is the place to go for the latest "information" (usually) rather than a technical query or help with reception issues.

Chris.SE: Yes, Chris, I understand all that now. Thanks for responding.

There's lots of useful and interesting information on this site - I have referred to it on and off for years. It's a real pity it's not being maintained.

I agree with you, it is a shame it's not being maintained, there's info here that you'd struggle to find anywhere else, if at all!

Mary ann McFadyen:

You are highly unlike to receive signals from the Black Hill transmitter in Arrochar but more likely from the Arrochar relay transmitter, however without a full postcode we can't confirm that.

That said, there has been some "Tropospheric Ducting" around causing interference, see Effect of tropospheric ducting on Freeview | RTIS for a simplistic explanation.
It can be quite variable, come and go within seconds, minutes or hours. It has been particularly strong recently which can wipe out your reception.
The BBC have also reported that these conditions could have affected your reception on Friday, Saturday and Sunday.

If you retuned when you had a loss of signals (this is never advised) then this usually just clears the correct tuning from your set, and this may be the reason you have no signals now.
Try a full retune again, now that signals should be more stable, and hopefully it will restore your programmes.
Post back with a full postcode if you still have problems.
