Andy: The BBC say that there is no problem with the transmitter. Given the millions of homes served by the transmitter, it is much more likely that you have a localised reception issue.

Chris Dunlop: Yes, the power measurement at the actual aerial is minute it usually calucalted in dBuA which are decibels, relative to 1 microampere, where
dBuA = 20 * log10( I ) + 120

Malcolm Springett: I would say that as the Crystal Palace transmitter is providing Freeview HD services to millions of homes in the London area, if the four HD channels were missing from everyone then people would notice.
Given that the headquaters of the BBC, ITV plc and Channel 4 are all within the reception area, I am sure they would notice if their HD service was off within a matter of seconds.
Also Arqiva, who run the network have extensive automatic monitoring systems that are able to detect and correct faults within microseconds.
This doesn't mean you don't have a reception issue, but it could still not be one caused by a transmitter faults.
One common cause of this kind of problem in the past, when it was not down to an in-home problem, has been faulty street lighting or security lighting.

Richard Baguley: C22 could be any of these - Find a Freeview transmitter by frequency | ukfree.tv - independent free digital TV advice but is actually BBCA from Belmont.
As Belmont also uses C25, C28, C30-, C53, C60- I think you can probably guess.
During switchover, BBC FOUR (and also the radio services) in on BBCA C55- and MuxB C66.

Richard Baguley: I would just wait until 23rd November 2011 and the final power levels will probably render your services back to normal...

Polly: It is not really advisable to put a wireless router device near another source of RF, even if the frequency used are totally different.

Chris Dunlop: Please see Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice .
I think you will find that the levels of power increase will create no additional heat that you will be able to detect.
