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 Redruth (Cornwall, England) mast?

Not sure if you can help? We live 1/2 mile and line-of-site from the transmitter aerial. When we were on analogue service years ago, we barely needed a receiving aerial - a paperclip would have done! Same with analogue FM radio - all the radios in our house have the aerials retracted or else they overload. Digital TV reception is rubbish though. We only have a small indoor aerial but why should we need more? You can see the transmission site out the window! You should be able to receive a signal on the fillings in your teeth! I can't work out if the problem is overload, or reflected signals, or are we living in the shadow of the signal because we are too close to the foot of the mast? I'm happy to buy a better aerial....if that is the problem, I just don't understand why it would be needed. Thank you.

Jonathan: What do the signal strength and quality levels on your TV show? If you have high strength but low quality that would suggest that the tuner is being overloaded by the strong signal, so rather than getting a better aerial you may well need to reduce the signal strength. Have you tried connecting the lead to the TV without the aerial attached to the other end and check the signal strength measurement? You may need to fit an attenuator between the aerial and TV, you only need between 75%-90% strength so try a 6db, 9db or even 12db attenuator which can be bought for a few pounds on Amazon or elsewhere.

I've checked aerial and amplifier connections which all seem fine, and carried out an auto re- tune, but I can only get bbc stations from the free view transmitter at fourlanes, Redruth, cornwall. Any reason why please?

John Foster :

Please provide a full postcode so we can check your predicted reception.
When did this problem start? Have you changed/moved anything/any equipment etc?

I can't find any current faults listed for the Redruth transmitter nor any in the last 5 days, and the transmitter isn't currently listed for Planned Engineering.

When you say you checked aerial and amplifier connections, have you checked that the aerial is still intact and pointing in the correct direction with its rods (or squashed Xs) horizontal?

Have you noticed any work taking place on any mobile phone masts near you? or have you received a postcard from restoretv.uk ?

Terrestrial reception is pathetic
If we need to watch BBC / ITV have to view through WiFi - local news not available !

Barry Holme: All BBC regional news programmes have been available on iPlayer for many years, you can select your region on the settings page. If you provide a full postcode we can take a look at your predicted reception and may be able to suggest what can be done to improve it.

Yes, a full postcode is needed for us to be able to help with advise regarding your reception.

Having logged into iPlayer to look at the News category last night, I see that all regions are now available, not just your own. My only gripe is that they should have a full week's worth available, not just the last 24hrs.
