Freeview reception at WD17 4PT
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.
You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.
You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.
These icons show the potential locations for 5G-at-700MHz services that may interfere with Freeview reception. For actual mobile device reception prediction (at 800-960MHz and 1710-2170MHz) see these phone operator's mapping sites: Three O2 EE VM

Hi, I am in Whitby and frequently get the message "New Channels found. press OK to update, etc...
If I press OK to update they are invariably gone by the evening.
Should not bother updating?

John: If you are receiving Freeview from the Whitby PSB only transmitter, then when you state that the channels are invariably gone in the evening are you referring to when you select one from the programme guide it results in a blank screen? or that they are not even being indicated in the programme guide?

When you select from programme guide we get a "No Signal Message"

John: In that case you should carry out a fresh retune and see if that brings results, if though it doesnt then this could suggest that there is a problem with your aerial system.
If though your TV has a manual tuning facility you could try a signal test check by selecting the tuning menu / manual tune and entering Ch55 (BBC) but NOT followed by pressing search or scan, because if any signal is being received but is maybe under the level required to produce a picture, then its strength / quality will still be indicated as cut off thresholds do not exist with this type of check, if nothing is being indicated then you either have a problem with your aerial system (or cable from) or your receiving equipment has developed a fault.
But though in cases like yours its always advisable to make one or two local enquiries for the purposes of eliminating any possibility that factors external to your household are responsible for the problem, such as interference etc.
By the way, you are indicated as being located at approximately 2 miles away from the transmitter (located in business Park) and with a clear line-of-sight to it.

Glenn: Refer to the terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The line between you and the transmitter is more or less in line with the motorway. I suggest that the motorway close to you is in the signal path (further away the signal path is far enough above the ground for objects on the ground not to affect it).
I suggest that could be traffic. Does it happen less on Saturdays and Sundays?

It's only been happening since Monday, Dave; since the original fault at the transmitter was reported. I've retuned the various boxes a few times during the outages (to no avail) but then they work fine again when the signal picks up next day (until they go down again. Could it be the heat / pressure? We've been here 3 and a half years now without these problems, so can't for the life of me work out why they would start now. Any other ideas?
Thanks :)

Dave Lindsay: That was my assumption as well, at first, but it's now greyed out on the engineering page as an 'old fault'; baffled!

Glenn: This site sources its information from Digital UK (www.digitaluk.co.uk/engineeringworks) and Radio & Television Investigation. The former lists no works for the Meridian region, except for Whitehawk Hill, Brighton.
R&T Investigation only reports on issues with BBC broadcasts. You can view it by clicking the link to the right of your posting.
The message engineering works message at the top of the Bluebell Hill page on this website is followed by a BBC logo, which means that it originated from the R&T Investigation site.

Glenn : Much as I can fully understand many peoples reluctance into having to do this, but when dealing with problems such as erratic reception a person really has to determine as to whether or not they are the only one that's being affected, because if they aren't then that saves them needlessly looking around for a fault that doesnt exist, at least within their own household anyway!
