Thanks for the answer - post code is EX34 8DR BUT the system was working perfectly fine until the transmitter was shut down for work so why would this upset my equipment please? There were definitely works listed on the day the problem started and this was confirmed by many people. Therefore it must be something that has happened with the transmitter - it cannot always be the equipment which always seems to fail or play up when something has occurred with your transmitter.

Sue: Thanks for the update re: your location, this indicating that your Freeview reception is from the Ilfracombe PSB only "relay" situated at approximately 0.5 miles from you, this transmitter broadcasting the same BBC and ITV programmes as Huntshaw Cross thereby giving the impression that the signal is coming from the latter, reception from Huntshaw Cross indicated as not being possible due to the signal path from the mast suffering from a sizeable line-of-sight obstruction from slightly under 7 miles prior to your location, a quick Google earth rooftop check revealing that all aerials in your area are vertically mounted and pointing towards the Ilfracombe relay.

The only other station indicated as a possibility for reception is Kilvey Hill, this station transmitting BBC & ITV Wales, and by being a main station broadcasting the range of commercial channels such as ITV3, Pick TV, 4Music etc, which its assumed are programmes not previously received by you?

As nothing is currently mentioned about the Ilfracombe relay as far as any faults are concerned, I would persevere with your retuning attempts after having checked the connections previously referred to.

Sue, I am also on Huntshaw. If you were previously able to receive Sky News and BBC Spotlight etc, then you were receiving Huntshaw (or just possibly Caradon in Cornwall). This would suggest that your Freeview box or inbuilt Freeview receiver was too clever and retuned itself without asking - not uncommon. If your receiver allows manual tuning (not only automatic scanning), then try retuning channels 48, 50, 52, 56, 59 (and 55 if you had HD).

If you didn't get Sky News, you were probably on the Ilfracombe relay (channels 49, 54, 58). If you received Welsh news and not Spotlight, you were receiving tranmissions from Wales. Hope this helps! If you need further help, please post again.

Thanks Michael - that makes more sense than a large blockage that must have appeared!! Will give this a try

Sue: In addition to that said, I can confirm that the Ilfracombe transmitter was indeed down between the hours of 1.33pm and 09.15pm on the 14th, this somewhat indicating that you are receiving Freeview from this transmitter.

Another point being, that none of the reception predictors (neither Digital UK or Wolfbane) indicate that reception is possible from Huntshaw Cross, and so I will also be interested in the outcome of your signal tests.

Hello

I live in EX22 7TQ. until a few days ago my Freeview reception both on the in built TV receiver and via You View box was fine then I lost block of channels including ITV1, ITV2, Ch. 4 Ch. 5 etc. on both. Tried re-tuning with initially no effect but now after further re-tune attempts I have them back but with Pixelation etc. indicating weak signal. As I say all fine before so is there any cause for this change like work on transmitter, change of signal strength etc.?

Also as an on going issue I do not get full strength BBC DAB signal here - commercial stations like Classic FM are always 100% so why can't BBC ones be if they come from same transmitter mast?

Thanks

Keith Tomlin: There is no indication is to any work at Huntshaw Cross. Digital UK publishes engineering works here:


Digital UK - Planned Engineering Works


I will make one observation and that is that PSB2 multiplex is on UHF channel 59 from Huntshaw Cross. PSB2 is the multiplex you are having difficulty with.

4G mobile services in the 800MHz band operate just above that, on C61 upwards. So any such services are pretty close frequency wise, with PSB2 being the closest meaning that chances are if any will be affected it will be that one.

The mobile operators have set-up a company to deal with interference issues and it will know whether there is a 800MHz 4G base station that has come on air in your area. It is called "at800" and you might like to enquire with them as to whether this could be a possibility: Contact us | Advice or general enquiries | at800

They will send out a free filter should this be thought to be the issue.


As for the question relating to DAB reception, what is the issue you allude to?

With digital reception (TV and radio) there is strength and quality. Strength is what it says it is. Quality is the degree to which the digits that make up the sound/picture are intact. Less than 100% quality may result in breakup of the audio/video.

As far as strength goes, the signal needs to be strong enough so that the receiver can decode the digits and so that any natural slight variances in strength aren't likely to leave it under the threshold required.

You might find, for example, that with a strength of ~70% you get 100% quality all the time. That's fine. The idea of using a percentage for strength is somewhat of a misnomer as it implies to the user that the higher the better when this isn't necessarily the case.

Different frequencies carry differently owing to objects in the space which the signals are carried. Thus, it's not uncommon for different channels to be received at different levels even though they are from the same transmitting station. If you ever used a set-top aerial indoors with analogue TV you would have likely found that out.

In the case of Huntshaw Cross, the power of D1 National DAB is 4kW and that of BBC National DAB is 2.5kW. It's also the case that this isn't the same power in all directions with each multiplex being different in this respect.

Your comment please
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.
