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!

What international borders are challenged by the Oxford TX? Maybe is to do with the channels in/near 800MHz? Or maybe the reason here is that the work is just not finished, so they don't know...!

@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?

@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!

@Chris James
BBCA is by far the strongest signal from Oxford, so you are either picking up the mux from somewhere else or getting signal overload

@Jack - Hannington has just gone through DSO - maybe you were getting some channels from there? Suggest you do the full reset and channel scan and check Mux frequencies as above
