Bill the only way I can think of in that case is to get an aerial attenuator and stick that in while tuning; it should only get the strongest then. You can remove it when the tuning's done.
There are loads on ebay just under £3 including P&P. I'd try a 9dB or 12dB to start with but it's hit and miss whether it'll work. Yo can start with a low value 3dB and work up, and also daisy chain them. At that price it's worth a try.

Steve, regarding your LG model number 19LG3000.
I have downloaded the manual for this and strangely it seems to allow for programs to be in the 800 range, which on most units indicates duplicate TV channels have been saved.
There is a Program Swap option however which may help, but I have a suspicion that the set may need to reboot itself from scratch.
Apparently many TVs and PVRs can crash (after all it's only a computer) and unplugging them from the mains for a few minutes makes them reboot from hardware.
This can cure a myriad of problems. My Toshiba failed to recognise the remote and unplugging it cured it. Worth a try.

P.S. You need to actually unplug it; just turning it off at the set doesn't always completely isolate it.

NJ, that's very strange as all the Sandy MUXs are around the same power, 170/180KW, and all their aerials would be similar. It's just possible that you have an aerial problem but that would be very rare; have you tried a different aerial with a higher gain?

I don't think any government would want to alienate most of the population by doing away with analogue FM broadcasting. They've been talking about it for years but always delayed making the decision. For a start there are estimated to be over 9 MILLION car radios that would need replacing, most hi-fi systems in homes and most mobile phones that have FM radio incorporated. It would be a mammoth task and extremely unpopular. If any government wanted to loose an election it would be a sure way of doing it. Yes, they'd like us to switch over to DAB but it's expensive and most people do not see the advantage; it's been very slow on the uptake and I can't personally see it really taking off in the next few years. If it were to happen the listening figures would plummet as most would not bother to upgrade and would give up listening to radio and just listen to their recorded music on the various equipment used today. The other point being that it's not suitable for car radios as the signal would be constantly dropping out instead of the lesser problem of dropping to a noisy or mono reception as it does sometimes with FM today.

I think people who promote DAB are conveniently forgetting about quality. Who wants to listen to music on a device that produces a sound little better than that which emanates from a smartphone? The government forces these things on to us for purely financial reasons with no choice or thought for the consumer.
The difference in analogue and digital is really noticeable, right from the times when recording studios went digital; and there are still perfectionists who spend a lot of money on analogue equipment for that very reason.
And what keeps getting forgotten is the fact that there are million upon millions of FM radios out there, in cars and in homes that would not be able to receive the main BBC radio broadcasts. Are all those listeners suddenly going to rush out and update their equipment; I think not? They'll either swap to local stations, that I believe will be the only thing left on the FM band, or simply stop listening to radio.

Sadly folks it's just interference due to foreign stations coming in strong. Happens on Digital signals just like it did on analogue terrestrial TV in the past when you used to see two pictures at once.
This type of interference usually happens when the barometer reads between 1025 and 1030mB; a little unusual to happen at 1010mB, the current pressure. As soon as the high pressure system moves away all should return to normal. However it looks to be with us for at least another week according to the forecast. If, like I, you also have Freesat that isn't affected. Mike.

Hi KMJ,Derby, sorry I did omit to say that it could also be adjacent transmitters that were causing the problem. Due to all the blame being placed on the poor old Sandy heath transmitter in so many previous posts I was just trying to shift the blame onto tropo and try to explain that the engineers at Sandy were not to blame. The signal strength seems to be good even at times of interference. I guess that's one of the problems with digital transmissions (less capture effect) and why the Air band will never be converted to digital; it just wouldn't work. Mike.

Hope you have a good internet speed over there in Wisbech Nigel if you're going to rely on the internet for your TV. Over here in Littleport we are lucky to get 4.5Mb and the promise of FTTC has moved from 2012 to the end of 2014 now, so who knows when. I get a good terrestrial signal here (SD and HD) and hope it's going to stay that way for the foreseeable future. Yes it will come eventually when all the country gets on fibre but they'll be a hue and cry if they do it too soon.

Steve, can't imagine what's happening. If you do a factory reset and then a Manual tune on those channels from Sandy Heath it should clear out all the old channels and put the correct ones in the correct order.
What TV or PVR are you trying to tune?
