The symbol shows the location of the Angus (Dundee City, Scotland) transmitter which serves 130,000 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 Angus (Dundee City, Scotland) mast?

Bob: On the subject of time factors involved with planned engineering works, these are never mentioned simply because of the nature of the work, as things aren't always as cut and dried as it might seem when dealing with RF equipment, as unforeseen snags can, and do, crop up.

The time factor involved being even less certain if said work involves anything connected with the mast, as the progress of the work is totally dependant on weather conditions etc.

However, on the subject of no signal on C49, although the signal path terrain indicator shows that the signal from the Angus transmitter (@ 11 miles / 236 degrees) is not quite line-of-sight to your location by being obstructed from around 1.5 miles prior to it, obstructions to a signal always having a greater effect when they occur close to the receiver, and with this possibly being the reason why you are not receiving any signal on C49, especially as COM channels are transmitted on half the power of the PSB channels, i.e: PSB 20Kw / COM's 10Kw.

Purely for a test, if your TV or box offers "manual" tuning, enter the facility and enter C49 into the box, but do"not" press search or scan but wait to see if anything is indicated in the strength / quality bars, as this procedure results in the tuner acting in the form of signal meter free of lower threshold for reception restrictions, likewise if anything is being received, it will be indicated no matter how low it might be.

Hi jb38
9:56 AM , again, I've done as you asked using the manual scan function in the ''set top box'' as a signal meter , but not scanning.

The signal strength varied between 28% most of the time and up to 40%, the quality was zero , with a very few odd moments when a pixilated picture showed only to freeze, and the [No or bad signal ] message appeared. So it looks like we'll just have to be patient until the work ends .

Re your info quote -> ##the Angus transmitter (@ 11 miles / 236 degrees) is not quite line-of-sight to your location by being obstructed from around 1.5 miles prior to it, obstructions to a signal always having a greater effect when they occur close to the receiver, ##

Dunnichen Hill is sort of south-south west of us, so that is probably the ''Obstruction''

Maybe later on we'll get a taller pole put up on the chimney stack to carry the aerial..

........so thanks for all the info and maybe when they switch back on after their work we'll go back to watching the Tour De France on ITV4 even if it is pixilated some of the time ..

Bob: Thanks for the update, your detailed findings on the outcome of the test having confirmed my suspicion as to the most likely reason for your problem, but which as you have referred to, might improve somewhat once the engineering work is completed.

One little point though, as far as possibly mounting the aerial on a taller pole is concerned, the general rule of "the higher the better" does not necessarily apply in every case, (transmission aerials excepted) as in situations where reception is non line-of-sight with the transmitter, its frequently found that a much better signal can be achieved with the aerial being mounted lower down at around gutter level, and with the aerial being tried to the left and right of the lower mounting position.

I only mention this just in case you, yourself would be installing a larger pole, if you are? leave the TV on the manual tune signal test screen whilst you adjust the aerial.

quote -->>##leave the TV on the manual tune signal test screen whilst you adjust the aerial. ##

Yes I might well adjust the aerial myself , ..............but eeerrr ummmh ahhh, how does one comminicate with ones beloved who is indoors watching said ''signal test screen '' as to when the aerial is in the best position, so that one can tighten the bolts holding said aerial , there was a TV show where contestants shouted Up a Bit , down a bit, left a bit .......Fire , having ones beloved shout instructions ''oot ra windae'' when one is up a ladder , may not be the ideal solution !!

Bob: Fully appreciating the points mentioned in your reply, but though, I wasn't actually suggesting that you do this yourself anyway!, as I am fully aware of the range of logistical problems involved in carrying out tasks of this nature, especially on one's own, safety being the main concern.

The only reason for mentioning what I did, was just in case you had considered this task as being within your scope.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
