Wayne Drury: No, this is not in any way "due to work preparing for the switchover".
I would suggest you look at the Freeview reception has changed? | ukfree.tv - independent free digital TV advice - the deal is that you don't pay a subscription, but the responsibility for reception is down to you.

Hi Mike
Thanks, I thought much the same as you but wondered if there is an issue with low power on Mux b as I see no level drop at all on the other muliplexes. I wondered if anyone else had experienced this as I dont think all engineering work is reported.

Briantist, thanks for the response. I have check the reception link you provided back at Christmas when we had the same issue for just of 2wks.
Our Ariel is new as of 3 years ago specifically for Freeview in our house and has been working fine up until the last 6 months on/off loss of channels. The worst it has been has been since Nov2010 through until now.
As for weather affecting, the other day it was crystal clear blue sky in Northampton and still no channels on those MUX I mention.
I accept reception is down to us public, but from a logic point of view, when nothing has changed in house/Ariel and I loose channels for over weeks and the weather has been clear, dry, wet, mist (i.e. never the same) its hard to believe it all down to something magical in our house/ariel is the cause. Particulary when we are aware the transmitter is in the process of being upgraded.
Whats concerns me most is after going out and buying a Freeview HD TV ready for the switchover. We are now having these kind of issues with standard Freeview, what come back if any do I have when I end up with no channel post switchover? Who do we call on 1-Apr when/if we have no channels post a retune?

Wayne Drury: The correct people to contact still is your aerial installer.
The transmission people are not responsible for anything other than providing the output at the specified levels and frequencies.
If you still have problems once switchover is complete, it is still down to you to ensure your reception works.
Your reception of Multiplex A (COM4/SDN) will not improve until 31st August 11, and Multiplex C (COM5/ARQA) will happen on 14th September 11.
Freeview HD will start on 13th April 11.

@ Nigel in Wellingborough
You live around 50 yards from me - carry on to the bottom of your road, nip over the fence and you're in my road lol. We've had reduced signal strength and power on Multiplex B but can just about scrape a signal with our loft aerial. All other multiplexes seem to be behaving themselves and with you being so close I doubt its an external issue affecting your reception.

wayne: I don't think you say whether or not you have a loft aerial, but if you do, that certainly won't help!

Nothing close that could cause interference. I have a surge protector (Monster Power) which handles all of the socket and has a pass through for the aerial. Tried it without that in place but no difference. First channel I can view tonight is Channel 18.
