For the last couple of nights I've had a semi scrambled/digital interference on Channel Four and then ITV on my new TV.

At first I thought it might be the TV going dodgy on me, but I checked other channels and they were fine. It got so bad that it was unwatchable at points and occasionally cut to black and then came back on again, as if the signal wasn't being sent. But just on those channels.

Has anyone else been having similar problems? My freeview is built into the TV.

Could be your aerial

I think it varies from box to box, but I have seen freeview boxes fail to recieve one channel, but happily display others.

Could be down to signal strength?

Do you have a decent aerial suitable for digital reception? Is it correctly aligned? AFAIK the direction that a digital aerial points is more critical than the analogue predecessors.

Bad weather? I know that my sky dish signal suffers in heavy rain ....

Could even be down to a poor cable from your aerial to the TV - have you got a cable into your TV direct from the aerial, or do you plug into a socket in the wall?

Check the coax plugs for poor connections

Cunning reduction of signal strength to force you to get Sky?

We had the same problem and had to get a man out to do the aerial and put a signal booster thingy on it. Works fine now.

My freeview reception is shocking and always has been, and I am in the centre of Edinburgh where it should be great. Drops out two or three times a week and often fails to show anything at all. Can't be bothered to do anything about it though, if it gets bad enough I'll get satellite.

Our Freewiew reception can suffer in bad weather but we have a 'set-top-box' in one room and that occasionally stops working properly but if I power off then on again it usually clears it.

Not sure the signal is very strong in the area but I know the Aerial is set right to the transmitter because I can see the transmitter mast from the roof (assuming Freewiew is sent from the same mast as analogue).

Small hijack.

Does anyone have a loft aerial for their freeview? Any recommendations or ones to avoid?

Thanks.

Get a wideband aerial, problem solved.

Dont forget until the switch over that the BBC channels are transmitting at 4 times the strength of the commercial stations. Only option is either Freesat [dish] or check that the aerial is a proper wideband chappy.

High atmospheric pressure affects TV RF signals, if your reception is marginal then this will be the problem, we have had high pressure recently. You need to upgrade your aerial or try a booster which might be an easy fix.

Use the postcode checker at digitaluk. Make sure you check the "I am in the aerial installation trade" and you will get a lot technical detail about your transmitter. For me, there is no signal for Mux 2 which is used by ITV and C4, and won't be until 2011.

I am going to get the Sky "Pay Once Watch Forever" as it only costs £75 for dish, box and installation. That's cheaper than I can get a dish installed for Freesat, and half the price of the "Freesat from Sky" package. As long as you play the Sky game it appears to be the cheapest way of getting digital satellite TV.

I had a similar problem a few years ago.

Most evenings my digital signal on Channel4 (& ITV) got messed up. If I tried to watch analogue TV, I saw wavey lines going across the screen.

This went on for months until I finally got the broadcast interference people to check it out (I forget what they're called?)

They came one evening and tracked the "interference" down to a house nearby who had a dodgy low energy lightbulb. Swapped the bulb and no more problems smile

Believe it's something to do with the re-organisation of channels pre-switchover, ITV/ch4 etc will eventually get their signal strength boosted and will improve.

We had the same thing, perfectly good reception for months with a new antenna, shielded cable and signal booster, then one day ITV/ch4 was rubbish.

There is engineering works going on for the switch over in a lot of places. Make sure its not that before you shell out.

Right, this link used to be very easy to use but seems a tad clunky noe

I may be wrong, but i understood that sky's freeview offering didn't include all of the freeview channels available, wheras the freesat one does.
