The symbol shows the location of the Midhurst (West Sussex, England) transmitter which serves 94,000 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 Midhurst (West Sussex, England) mast?

Hi all,
We have contacted Humax (re: loss of BBC channels on PVR 8000T) and all they keep saying is do a manual tune. We have tried this, along with the factory reset, tuning with no aerial etc. etc, but all to no-avail. Not sure what else we can do, will things return to normal after 14th March or will the BBC Mux still be on far more power than the others (which has been hinted could be our problem, but how too much power affects only one device we don't understand)
Are we going to be forced to throw the Humax away and buy another one?
Any suggestions gratefully received.

Darren Ellis: Purely out of interest can you actually receive the low powered (2Kw) ITV1 & ITV3 muxes? as you are not predicted as being able to do so until March 14th.
However the point of this being, that if you can receive the aforementioned channels then unlike what the predictor suggests you are likely to be located in a lucky spot for reception, the downside of this being that the much higher powered BBC (20Kw) mux at only 6 miles away could well be causing your PVR to suffer from signal overloading problems, as the tuner fitted in that model (albeit of older design) is more sensitive than some found around, but because of this otherwise plus point is likewise more sensitive to be overloaded.
To eliminate the possibility of an excessive signal applying, if you have access to a set top aerial then just for a test plug that in and carry out another manual tune on Mux Ch55 and see if anything comes up, if it does it doesn't really matter what like it might be (severe glitching on picture etc) as the main point of the exercise is whether or not you get anything.
Should this procedure bring results, then you will require to fit an attenuator of at least about 10dB or so in line with the aerial socket of the Humax to slightly kill the signal level, as come switchover ITV is also likely to vanish "if" the problem is caused by signal overloading.
On the other hand though, if nothing you do signal reduction wise results in the BBC being received then even although the 8000T is seen listed as being 8k compatible it might not be quite so stable as Humax maintains, the proof if this being if ITV1 also vanishes on the 14th.

Hi JB38,
Thank you so much for your advice. We disconnected the Humax and plugged it directly into the aerial lead from the aerial on the roof (no booster) and tried to tune it. We received no channels at all, the signal strength was down to around 20% with very poor quality on all channels/muxs. We then plugged in just a booster and that directly into the Humax and tuned. We were back to square one with 80+% strength and no quality on channel55/BBCMux and around 60% strength and 100% quality on all the other 5 channels/mux's, even channel65 with ITV1 and 2 etc. We're going to wait until after the 14th March and see what happens and make a decision then.
Thanks for all your advice, if anyone has any more ideas we'll welcome them.

Darren Ellis: Thanks for that update on the situation having taken note of all you have reported, however on analysing same I have to say that I feel that your BBC problem could still be because of signal overloading thats causing instability to occur in the Humax 8000's receiver.
I have to point out that the aspect about being in this type of situation that can be "very" misleading to many is that the strength / quality indications seen on the receiving equipments indicators can in most cases be "exactly" the same as that obtained if from a weak signal, this being as the result of the excessively high RF level in the tuners front end causing partial instability to occur, and with this having a knock on effect in the oscillator circuitry dependant on the channel selected, the aforementioned instability corrupting an otherwise clean digital signal resulting in it only being partially measured hence the low readings. (exp somewhat simplified)
Needless of course to say, that the important part of a digital signal, namely its quality is always first to suffer when instability strikes, and as the instability level rises the quality is frequently seen to drop to zero, this exactly what you experienced when you plugged the booster back in.
I do of course realise that you cannot receive the lower powered multiplexes without the booster, but as mentioned in my original posting you are not really officially predicted to be able to receive them properly at present, and although you obviously can do with the booster I feel that you might be paying the penalty of having them by causing the tuner to be overloaded.
If its at all possible I would still like if you could manage to try a set top aerial in the manner previously described, as the outdoor aerial straight into the Humax without the booster is still not as good a test, especially where an 8000 is involved, but should this not be possible then I will look forward to a further update come the 14th as that will be the day of reckoning, so to say! as then if its not a signal overload problem then it doesnt leave anything else other than the not so nice issue of 8k compatibility.

Thanks again JB38.
We'll see if we can lay our hands on a set top aerial and carry out your suggestion. We'll see what happens after next Wednesday too.
Thanks again for your advice, of all the people to respond (including Humax who have been no help at all) your suggestions have been the most helpful.

Hi there, really glad I found this link.. We live in Chichester and do not know much about the switchover ( even though we are trying to learn ) however we seem to have gone down to 29 channels from 89 via our bush LCD42911FHD3D , 42 inch tv we only just bought! It has an inbuilt "Freeview" tuner and we didnt have any problems before last week, Now suddenly we have terrible signal.. the 29 channels we do have keep cuting in and out /pixilating too. Could anyone help with this? Im guessing the March 14th date everyuone mentions is part of the reason? Cheers,
Stephen and Joanna

Darren Ellis:
Just thought I'd comment that we are near you (Greatham) with a Humax 8000T and it has no problems (either before or after 14 March).
We just did a full default setup and all channels came in no problem.
We have a televes DAT 45 active aerial and 4 way amplifier/splitter on the roof. I installed this in 2006.
Just so you don't throw away your 8000T!

Stephen: Which channels are you getting now (but pixelated)?
See if there are logical channel numbers 800 and upwards.

Martin: Although on-site reception reports (which I welcome) are always useful in building up a picture of what like things are like in certain area's, a fact that must always be remembered is that when in an iffy area for reception such as applies all around Liphook and district, is that the signal strengths received at a given spot can be found to vary quite widely even over a few yards or so, let alone at the up to three miles or so away such as is indicated exists between yourself and Darren.
As I am unaware of your exact location I carried out a check using a test code on Greathams post office and which revealed the area as being slightly worse for reception than Liphook, with an element of this still applying after switchover, and its because of this fact that I feel you are in effect "getting away" with the aerial system you are using, as its almost certain that you wouldn't if in a slightly better signal area, this even allowing for the slightly misleading gain figures claimed for aerials such as the DAT45, and indeed a number of others due to the fact that the figures are mostly obtained when under a strictly controlled test situation, this never at any time being replicated in practice hence are very much lower.
Signal overloading problems is nothing new, as its something almost guaranteed to be experienced by a handful of people in practically every area in the UK where high powered switchover has taken place at the main transmitting station that serves them.
I will agree with your comment regarding the 8000T though, at least for the time being.

Darren Ellis: Regarding the set top, yes, I would be interested to know the result, but keep me posted with regards to events after the 14th when a re-tuning event takes place as well as ITV powering up and changing its transmission mode, although its April 25th before ArqB (Mux Ch50) powers up and with a break until the next event takes place on Oct 4th.
