kevin roebuck: See postings above and on other pages. The inversion effect is causing signals from distant transmitters to carry and interfere with local ones. Judging by postings on this site, it's affecting a large swathe of the country.

SeeMoreDigital: According to Digital UK Coverage Checker, Waltham's COM7 will be at 8.7kW. The figures quoted on this site appear to be former expected ERPs, and this is the case with most transmitters chosen to carry the new mux. The site owner is waiting for Ofcom to publish the latest figures.

Mark Lewis: Unfortunately that is probably unlikely.
The new multiplex broadcasts exclusively on C31 through to C37. Increasing the power would result in more areas of overlap where the signal isn't usable because another transmitter on the same channel is causing too much interference.

Mark Lewis: If you are using manual tuning and there is an option for DVB-T or DVB-T2, then select the latter for this and other HD muxes.

Ian Edge: The signal which carries Movies4Men is broadcast from Winter Hill directionally towards Manchester. It is also transmitted on much lower power than the other channels.
I would definitely suggest that it isn't an issue caused by 4G signals operating in the 800MHz band.
The signal is probably bordering being just strong enough for your TV to resolve a picture. Perhaps it has dipped a little (as strengths vary a bit due to atmospheric conditions).
If you have retuned then its proper logical channel number (LCN), which it may have taken up, is 51. If, for whatever reason, the standard LCN isn't taken up, then it will, as you found, be placed in the 800s (could be anywhere).
If you don't have it stored on your TV, because you've retuned, then go to the manual tune screen and tune to C57 (762MHz).

Ian Edge: Try connecting the aerial directly to the TV and see if it picks it up.
If this has only just happened then I wouldn't do anything hasty. There have been a lot of reports of poor or non-existant reception across a lot of the country, although not generally the North West. This is caused by atmospherics causing distant signals to travel much further than normal.

MikeP: The thing is that this site, above the box to post a comment, says to carry out the reset procedure!

Jade: No.
The new HD channels are available from 30 transmitters, on lower power then the other channels from those transmitters.
The service from Mendip doesn't start until some time next year, date unknown.

Frank: I wouldn't do anything hasty. The inversion effect has been playing havock with reception across a large swathe of the country from Sussex and Kent in the south upwards as far as Yorkshire, if complaints of poor or non-existant reception on this website are anything to go by.
I would certainly see how often it happens and not try changing the aerial the first time it happens. It may be that it doesn't happen that often and that using Rowridge may be worse. If you haven't allowed a long enough period to see how it goes then you won't know.
If it does appear that Whitehawk isn't good enough then I suggest that you turn the aerial anti-clockwise to face Rowridge (keeping it in its vertical orientation). From there tune in the PSBs from Newhaven (seeing how they are with the aerial pointing a little off-beam) and the COMs from Rowridge.
