Hi Briantist - Just noticed that in the channel list for the SDN mux, ITV3 (Channel 10) seems to be missing from the list. Just a small point I know. Just wondering if there was a reason for this.

Jim: Since switchover, i've been getting good Freeview reception on all channels from the Oxford TX. Recently, however, D3+4 channels are continously subject to picture and sound breakup while there's no problem with the rest. I can't find any fault reports on this - can you advice, please? My postcode is OX25 6JQ.

The Oxford COM power up and mode change to SDN mux that is planned for 18 Apr 12 will not affect the already high power D3+4 on C60- so check you are actually receiving Oxford and not Sutton Coldfield off the back of your aerial - its almost exactly 180 degrees off and C46 passed first in most box auto-tuning!

Could Richard have accidentally tuned to Hannnington? From Bicester, Hannington is roughly the same direction as Bicester.

Please advise whether the main switchover work is complete or not. Since this work started I have gradually lost all channels except for the BBC ones (1, 2, 3 & 4) despite multiple retunes (aerial pointing Oxford). Aerial installers confirm there is virtually no signal at this location (Swindon SN5) despite the high gain aerial. This is a sad sate of affairs when considering ITV and some others were receivable back in the analogue days.

Thank you.

"...From Bicester, Hannington is roughly the same direction as Bicester."
Why did I write that?
I meant to say that, from Bicester, Hannington and Oxford are roughly the same direction.

@Ralph: see above MUX info, the COM muxes are currently on low power 12.5kW ERP, and using a less robust broadcast config, but work on the MUX with ITV1 is allegedly complete - so do check you are tuned to the Oxford C60- MUX. I'm much closer to the TX than you but it seems the BBC MUX comes through with much higher apparent power, it may be my aerial system, the higher frequencies or the fact that C60- is very close to C59- and both are 'negative offsets'. Might also be interference from the low power Hemel Hempstead analogue TX is broadly the same direction.

Once London Crystal Palace and all its dependent transmitters have gone through DSO (18th April 2012) the COM channels will be increased to 50kW ERP - the 6dB increase might be able to take your signal above the digital cliff-edge, but don't expect miracles - bad weather, atmospherics, leaves on trees are all potential disturbances to which you will not have much safety margin.

And then you will only have a few years till 4g mobiles start using C61-C69 - have you considered Freesat?

Thanks for the reply mst.

Only ch53 shows any signal and that is poor, manually tuning / searching all other channels shows nothing. New high-gain antenna, all cables and tuner checked and replaced. Sure there are other methods of receiving broadcasts but I think its a sad to go from 6 working channels (showing different content) before any digital work was started to 4 channels (all basically the same because they are BBC) after. Sadly More4, Film4 and ITV etc were receivable earlier this year.

What surprises me is how anybody thinks this is half acceptable and is probably why the UK lags behind most other countries when it comes to anything technical.

I like the allegedly clause and if anyone reads these posts who is actually doing the switchover work then perhaps they could present a true picture of what is actually happening and when so people don't have to go and buy their own satellite just to get basic TV reception (in the very small rural backwater that is Swindon).

I am sure everyone living in Oxford is ecstatic with their reception.

@Ralph - use "change address" on this official site to real predictions - which claims plenty of choice in SN5 - but almost exactly in between Oxford and Mendip

Postcode Checker - Trade View

Also has details of dates when things change, but doesn't always make clear what/why!

Your comment please
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.
