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?

lisa steward: No reported faults, and you should have a strong signal.

It is possible to have TOO STRONG a signal. Are you using any amplifier? Try without if so.

You could phone a LOCAL aerial fitter, who would know any local issue

Hi Lisa: as Steve P has already said you may have too strong a signal and should take any booster/amplifier out of circuit.
But the other thing you ought to do is a complete new installation/factory reset first with the aerial unplugged - this clears ALL previous settings, & then repeat that with the aerial plugged in.

If you and your neighbours are in a block of flats using a communial aerial you will probably need to get onto the landlords to get it sorted.

NN13 postcode, BBC1/2/3/4 have too strong a signal, so installed an attenuator, if I turn down the signal to resolve the above I lose all other channels.

Why would the signal stregnth on channel 53+ be more than on channel 60-?

What do the + and - signs after the channel numbers mean?

My freeview recorder is a Technika AEDTR160S7.

PT - I'll give you a quick answer but hope someone more expert will follow!

Assuming the 53+ and 60- are the same power it might be that your aerial works better for one than for another - especially one like 60 at the end of the range in use.

IIUC the + and - mreans they are using slightly different frequency to the "standard" for that number. I think I've seen a suggestion that some boxes don't work well with -s.

@Peter

I see the same wrt to C53 and C60 with a wideband log-periodic which should work from C21 to C68! Need 6dB attenuator to get 53 off 100% and that hurts the quality on others. It is hard believe they are both at same power at same height on the mast. BUT I'm not too sure what my boxes actually report for signal strength. It may actually be an analogue SNR (quality being a digital Error rate), so the problem may be noise on C60 from a distant Tx, Salisbury perhaps? Precise alignment of aerial may help.

Pete Turner: Hi, most of your question has been answered by Steve P. & mst. Aerial postion can make a difference, as can the +/- shift off the centre frequency, this being receiver dependant - not aware of any specific issues with your PVR, it's a Vestel clone - you can always google, but there's lots to read!
If there is a significant difference between C53 and C60 it could indicate degraded aerial (if old - water getting into connector box could cause this) likewise degraded (or cheap) coax or maybe aerial is a group B instead of C/D. However if you are going to replace your aerial in the future you should go for a wideband to cope with projected new COM muxes 7,8,9 sometime after ~2013.

If Sky is from a RF output, probably one of the new broadcast channels is interfering and you will have to change its frequency.

Otherwise, no postcode, no can help.

Channels 55, 59 and 62 were unused in analogue days from Oxford, so if your Sky system used one of those channels for your RF feed, you will need to retune your Sky receiver output channel.

Go to 'Services' on the handset, then press 4 then 0 then 1, then press 'select' to view the installation menu. Choose option 4 (RF outlets), then choose the channel to which you wish to retune. Then scroll down to 'save new settings'.

I use Ch 22 for Sky, Ch 25 for VCR and Ch 28 for DVR - all work fine.

If you plug in your postcode top right this site suggests spare channels.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

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.
