Do you have a roof mounted aerial, as loft/indoor aerials don't work well with Freeview? Also, how old is your aerial? If it is more than a few years old, it may be a group "A" aerial which is the wrong design for Sandy Heath digital TV services. If you can hang on until the 13th April and try to retune then, you should get the BBC channels if my asumption about your aerial type is correct. If I am correct, and going foward from 13th April, you will need to change your aerial for a wideband type to receive all of the other Freeview channels.
Hope this helps,
Adam

alan carson- You may receive signals from a relay(Dallington Park). Do you currently only receive analogue channels 1-4? If so, you will receive MUX 1 and 2 from DSO and no digital signals until then.

LutonFan makes a good point there. If your aerial points West, you are using the Dallington Park relay transmitter, in which case from the 13th April you will get a "Freeview Lite" service, that is to say you will get the main ITV and BBC channels, Channel4, Channel5 etc, but not all other digital channels. If it is Dallington Park you are receiving, no aerial change will be required. If your aerial points East, then it is Sandy Heath you are using, and again from 13th April you will get ITV, BBC, Channel4, Channel5 stations without an aerial change. If you find that you do not also get other Freeview channels (i.e. Yesterday, ITV4+1) from Sandy Heath, then you will need to upgrade to a wideband aerial to receive the full Freeview service.
Dallington Park will only ever carry the main channels.
Hope this helps,
Adam.

I am guessing that the football team you support is Luton Town, although your location is given as Northampton. Why do you not support Northampton Town? Is it beacuse they are cobblers?
Just a thought!
Cheers,
Adam.

When DSO phase one happens on March 30th will the BBC Freeview channels be turned up to full power, or will we have to wait until the April phase 2 date to see the full power turned up?

Craig: At DSO day 1, the BBC A multiplex launches at full power. I believe this is true at all sites, even where a temporary channel is used.
The BBC A multiplex takes over the frequency of BBC Two (analogue), so you must retune your Freeview box even if you already have perfect reception of Multiplex 1. The current low-power Multiplex 1 will stop transmitting. You should do a complete first-time installation to clear the existing BBC channel information.

Wide band Labgear aerial mounted on 20' mast on gable end of bungalow.
Occasional brief loss of sound. Is this likely to improve with increased transmission power from Sandy Heath?
