It is highly likely that the current weather patterns are causing troposhperic lift conditions, which means that signals from some sources travel further than expected normally. That means you could experience reception from transmitters not intended to serve your area.
Do nothing. Do not retune. Just be patient.

Sorry MikeP both Bracknell and Reading are both well in the service areas of both Hannington and Crystal Palace (including London Live and That's Thames Valley local multiplexes). London Live has been blocked ever since the Hannington local multiplex was turned on in February, nothing whatsoever to do with weather related tropospheric propagation.

Davews:
The two transmitters are in different directions from Reading and Bracknell, one roughly south and one roughly east. A good correctly positioned aerial should be able to differentiate between the two possible sources. If necessary it may be worth considering a higher gain aerial as they have a narrower reception pattern but may need the use of attenuators to reduce the signal to acceptable levels for you equipment.
London Live is on the LW multiplex from Crystal Palace and that transmitted ob Ch29 (538 MHz). It is only a 20kW transmission, so much less than the majoprity of the other services. I cannot find any reference in the frequency allocations charts for That's Thames Valley, perhaps they have not been updated as yet. I have asked by email for a clarification from That's TV, who run That's Thames Valley, for the full technical details of their transmissions. If I get a reasonable and accurate answer I'll pass on the information.

MikeP: It's already been widely reported that the local mux for Reading is on C29, with plenty of people complaining about the interference caused by the significant overlap of the London local mux on the same frequency. It does seem a strange choice for the same frequency to be allocated on two transmitters which have such significant overlap (Crystal Palace provides good coverage across much of Reading including good reception of the local mux, at least until the Reading local mux started).

Thanks for that. Even That's TV doesn't seem to realise the problem it is causing! Who ever allocated the same frequency to two different services when the transmitter service areas overlap so much is clearly not blessed with knowledge of how radio signals propogate and then cause interference. Perhaps a strongly worded communication to Ofcom is needed?
Best regards

Here in Bracknell Crystal Palace is slightly south of east, Hannington slightly south of west, more or less opposite directions. I have a high gain group A antenna on Crystal Palace installed by a local installer a couple of years ago. Hannington is bang in one of the rear lobes. Crystal Palace and Hannington are more or less equal strength here, half the houses have antennas on one, half on the other, take your pick. To have both local multiplexes on UHF29 is just crazy.

We're in Reading and have dual Crystal Palace & Hannington antennas, with CP generally giving the better signal. Looks like the new multiplex for the Reading area on channel 29 for That's TV is only serving to obliterate London Live, which we used to receive reliably until recently, so we're experiencing the same as Davews is in Bracknell, with a signal strength of 7/10 and quality of 0 now indicated on our Panasonic TV. So from our point of view the channel looks like a poor choice too.

MikeP: I would have thought not only a "strongly worded communication to Ofcom" but copying it to Arqiva as well as I would have expected them to have been involved somewhere along the line, not only with advice on channel allocation, but provision of the transmitter.

MikeP & Chris.SE: I'm not sure what effect a strongly worded letter to Ofcom is likely to have, given that they alone are responsible for frequency allocations and would be fully aware of the overlap in coverage between Hannington and Crystal Palace. I suppose they might be able to offer an explanation of why C29 was chosen, but I wouldn't expect any more than that.

StevensOnln1: Whilst you are correct that OFCOM are ultimately responsible for frequency allocations, they take advice from Arqiva (and others). I'm afraid you have absolutely no idea how they will respond to complaints about the interference by the overlapping coverage and they certainly may not be aware of the extent of the problems it's creating.
One thing is certain, without affected viewers making complaints, nothing will happen. Arqiva may also not be aware of the extent of the issue and may well decide to take a look at the problem.
So not only do I disagree with you, but I advise people who are affected to make written complaints as I suggested.
Further down the line, if OFCOM are failing to respond to the issue, then writing to one's MP and the Secretary of State for Culture, Media and Sport would be a line of action.
