The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 Oxford (Oxfordshire, England) mast?

Hi again
Got home from work, looked at Ch53 and it was all back but sound was low. So I fiddled with the scart and lost the picture again. I've now changed the scart and rescanned and all seems back to normal but I wasn't aware that the scart would have this impact. I've now got all channels with Ch53 Oxon & Bucks showing 64% strength and 100% quality. Got any explanations because I'm baffled!

Martyn: Well you have good reason to be baffled, as its virtually impossible for what you were moving around to have any affect on the signal level, this making me feel that the second last paragraph in my reply (i.e: out with your control) might well be the case, and with whatever was causing your problem having either corrected itself, or having been corrected.

Just to satisfy my curiosity though, when I had requested that you try a manual signal check on Sandy's Ch27 and you reported back that it was showing 16% strength, could you possibly try that again? as should by any chance you find that it has also come up in strength then that could indicate an intermittent connection problem on your aerial system.

Another thing being, that although you will most likely have already set this to "off", but if your aerial goes through the Humax and then into the TV, check to make sure that you have the "power saving on standby" switched off on the Humax, as that partially kills the aerials RF loop feed to the TV. (this setting under "miscellaneous")

Ch27 is still the same and power saving is off. Ah well, unexplainable I guess. If it goes again I may consider switching over to Freesat and having a new LNB fitted for a PVR as I've only got a single one now. I can't stomach the thought of giving my cash to the Australian phone hacker!

Martyn: No problem Martyn! and pleased to have been of assistance, as although I mainly deal with non domestic RF equipments I find faults such as yours on the domestic side of things to be much more interesting.

And by the way, your findings on the Ch27 test not having altered any "is" as you will probably have gathered good news, as that indicates that your Ch53 problem "was" caused by external reasons.

Regarding Freesat, its something I have no hesitation about in recommending it to anyone, as its the only mode with a virtually guaranteed 99.9% level of reception reliability.

Quad block kits for a Sky dish can be obtained for as little as £10.00 from a number of e-bay outlets and are simplicity to fit by then virtually being a push fit onto the end of the arm "if" its a rectangular one, or alternatively if its an older dish with a round arm you loosen the 40mm collar clamp and swap the blocks over, then run another coax cable to the lounge or wherever.

Regards / jb.

I see from the Digital TV site that in October 2013 I will be required to re-tune and from that date I will receive fewer channels. Surely this cannot be true!

Algernon Black: You haven't provided a link to the said page.

As a test, I entered the post code of The Sherborne Arms into the Digital UK Tradeview predictor:

Postcode Checker - Trade View

The retune in October of next year is because SDN is moving from C62 to C50. At this location the predictor considers the current channel "good" and the future channel "variable".

The predictor, as with any predictor, in no way suggests that anyone "will" or "will not" receive anything. It should merely be taken as a guide, being mindful that there are many many variables, not least that a post code is a massive space where signals vary and of course the fact that Royal Mail does not deliver television signals.

All I would suspect here is that C50 is used by another transmitter and that it has calculated that it may act to degrade reception. That does not mean that it will.

I wouldn't be concerned about what the predictor says; I would just be mindful of it. What matters is what actually happens.

After lots of instability my systems seem to be behaving fine now (all crossed). However I have recently noticed another issue. Some of the stations seem to be transmitting in different picture modes, which can be altered with the handset, but it is certainly a new event.

Any thoughts. Having checked each set the set up is as per correct screen mode.

I have been having trouble with Samsung Smart TV dropping its channels repeatedly. I have a Humax Fox T2 connected to it and the powersave on standby was set on Humax. I had to call out someone in the end who told me to take the powersave off as this was causing the problem. I did that and have had no problems since. Just thought this tip might help others

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.
