Nobody should worry at this stage about Freeview reception. In June the power levels will be multiplied by 5 (or by 10 for HD) so all problems are likely to disappear then.

george mackay: I assume you're using a communal aerial. The weather will have some effect, but the most likely reason is that some cable or connection is letting water in, stopping the highest frequencies from getting through properly.
It's also possible that the aerial wasn't swapped for a wideband or semi-wideband (Group E) type for Freeview reception - multiplex C might have been OK as it's only just out of the old analogue group, but multiplex D is way outside. That said, I'd expect it not to work at all, rather than just working occasionally.
All post-switchover multiplexes are within the old analogue group, Group B, so there's really no point in changing the aerial with three months to go.
If other people in the block are getting reliable results on Mux D when you aren't, ask if you can temporarily swap your box for theirs. If your box works in their flat but theirs doesn't work in yours, it's probably something in the cabling to your flat. Get the property manager to sort it out.

Hello, I note that there is references being made to possible changes being made some transmitters up to 2013. Is this for frequency changes or for power outputs or both?
Secondly I note that a considerable number of your correspondence are having problems in receiving the HD frequencies. Is Blackhill radiating the HD frequency (59) in the same pattern as the rest of channels or is that as I read somewhere that the signal is being beam at the main population areas e.g The cities?

I have had a problem with BBC SD channels since Sunday in that my TV will resets itself every minute when viewing these channel. (i.e. switch off and on again). All other channel have no problem including HD. I have a Sony KDL-40HX803. Is there any switchover testing in progress? I have rescanned the channels. Aerial is new and roof mounted.

John: The BBC made some changes to their Red Button interactive service programs about a week ago that caused problems for some Humax boxes. It's possible that they've made another change that's causing a problem for your TV.
It's worth checking you have the latest firmware. On the remote, press HOME, then select Product Support, System Information and check that the version is PKG4.092EUT-0108. If not, see Televisions & Home Cinema|
Sony Support Europe for manual update instructions.
Updated firmware is broadcast periodically but with a vast range of different TVs, PVRs and set-top boxes out there, it may be a while before an update for your TV is repeated. It's worth leaving it set to automatically update itself, which means leaving it in standby overnight.
You can contact the BBC by going through their reception page at BBC - Help receiving TV and radio and entering your postcode in the top right. It will take you through a general reception troubleshooter first, but if you keep going you eventually get to a form where you can send an email. (RG47SH)
