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?

Briantist. My postcode is HP21 9TZ. It's mainly ITV3 which is unwatchable and even sometimes shows no signal at all. It used to be fine so I have to assume it's something to do with the switchover as all my other channels are ok. I've got a new aerial, leads etc. I'll wait until the switchover is finished before I try anything else. Thanks for your response.

John J: Looking back across your old posts I think you may have gone overboard on the aerial, and something's overloading. If you have a booster, take it out. Try adding an attenuator.

If this *is* your problem it's about to get a whole lot worse, starting with Wednesday's power-up of the BBC multiplex.

Do also check that your box hasn't selected Sandy Heath on C31 rather than Oxford C51. Some boxes have an automatic overnight retune feature that happily overwrites a careful manual tuning of the correct channels!

Hello Brian,

You used to show potential conflicts for co-channel interference, but this has now gone. I am in a multi-transmitter area and have two wideband aerials, one pointing towards Oxford, and the other to Sandy Heath. When Oxford switches tomorrow and later this month, I can see several conflicts as follows (some are existing, which already block signals from both the relevant transmitters):

14th September:
ch29: ArqB Oxford / D London
ch31: SDN Sandy / HD London
ch34: BBCA Oxford / C London
ch48: ArqA Oxford / ArqB Sandy
ch68: 2 Oxford / A Hemel

28th September:
ch55: ArqB Oxford / 2 Hemel
ch59: ArqA Oxford / B Hemel / D3+4 Luton
ch62: SDN Oxford / C Hemel

Could you please restore this facility, as it's really useful to see which signal is the strongest; for example both the Hemel and London signals are strong enough to cancel out Oxford at the moment, even though I have no aerial for London.

Talking of signal strength, both the London and Sandy signals are strong enough on BBCA / 1 and D3+4 / 2 to be picked up on the Oxford aerial, without signal break up!

Regards,
Nicholas
