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.

I think these days best practice is not to have socket plates at all; just to bring the coax through the wall direct into the set.

...start to watch the channels rise in the progress bar, then as soon as they get to Mux Ch50 re-connect the aerial and that will exclude anything other than Oxford from loading".
UHF channel 50 is used by Hannington and Sutton COldfield. If you want to store just Oxford, try to reconnect the aerial when the scan is after 50 but before 53. This can be tricky, particularly if the TV dosen't show UHF channel numbers.

Hello,
Since switchover, I have had no EPG, but can recieve all 5 muxes. I tried rescanning, but this has not helped. The EPG is still blank, so I'm having to set timer recordings manually, which is time consuming, as I have to scroll to the start and end times in one minute increments!

Nicholas - I recall that some boxes use an EPG source that has stopped.
If you post here - or google - your box/TV Model you may see something.

I have an icecrypt T5000. On one particular aerial socket, it is only picking up the BBC mux (connected elsewhere in the house it is fine as are the other freeview boxes/TVs in the house)
There are two other aerial sockets in the house and all three are run off a 4 way non-amplified splitter
My postcode is NN13 5PN and the (loft) aerial points to the Oxford transmitter.
I have done the reset advice etc and this freeview box is only connecting to an analogue TV with no other devices connected
Is an amplified (powered) splitter likely to fix this problem or could it be something else ?
Thanks in anticipation

Alex - what happens when you use one of the other boxes on the particular aerial socket?
Can you get at the splitter? Try switching the connections and see if the problem moves, or is linked to the down wire.
Remove socket and check for dead beetles etc.

Hi yes it sounds like this one socket isnt getting enough signal, this could be due to a wiring problem, i.e. poor quality cable or poorly made connections at the end of the cables (the brading should never be touching the centre core!), or simply that splitting the cabel that many ways is killing the signal too much. Try checking your connections first, if that still fails, use a masthead amp such as this (http://tradeworks.tv/acatalog/Vision_4_Way_Variable_10-20dB.html), this can be powered remotely - ideal for lofts with no plugs, or a simple TV amplifier such as this (http://tradeworks.tv/acatalog/Triax_4_Way_TV_Amplifier.html).

Paul: Yes, Hannington might well be, but I think you are overlooking the fact that apart from it being roughly 50 miles away from Oxford its also only transmitting on low power (20Kw), so if any signal was actually received (which is very doubtful) then its most unlikely to be at any level that a box could lock onto.
Emley Moor is the only station that does transmit on high power on both Mux Ch's 51 & 52, but once again at a distance that it also can be disregarded for the same aforementioned reason.
Sutton Coldfield does not use Ch50, it having been previously used by Ch4 analogue, although I assume that you have seen this error on Wolbane's site (or what was) when they refer to the PSB3 Mux, as it should be Mux Ch40.
As it was anyway, the box being used did not show channel numbers in the progress bar, making this part of the info supplied to be a bit on the academic side, although I will agree that the aerial out procedure until a certain channel is reached is always a bit iffy, especially when so many stations have their multiplexes weaved between that of other stations.

Thanks for that feedback.
I don't know where I read that SC uses CH50. Thanks for correcting me.
Hannington, even on its current power level, is a problem in north Oxfordshire, where Hannington and Beckley are the same direction.
