J Green: According to Digital UK Tradeview, yes, all muxes from Whitehawk will be on the full final power on 21st March.

Rachel: Which transmitter are you receiving from? (Or what regional programming do you get?)
I had a look at your road on Google StreetView and see that quite a few houses have two aerials; one on Crystal Palace (London programming - pointing east) and another on Hannington (Meridian - pointing west).
Those that have one aerial (that I saw) were all on Crystal Palace.
The power of the HD services from Crystal Palace is on lower power than the standard definition channels. Hence, if your aerial is directed at Crystal Palace, then you will probably have to wait until switchover on 18th April.

Dick: Check that BBC1 is tuned to UHF channel 60 for Whitehawk and not channel 24 which is Rowridge.
If it is tuned to Whitehawk, I wonder, could be too high a signal level? See Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice

Pat Smith: Not sure about your problem, but channel 25 from Ashbourne is "BBC A" multiplex which carries standard definition TV and radio. Channel 22 from Ashbourne is "BBC B" multiplex which is the HD one and carries ITV1 HD and Channel 4 HD as well.

Pat Smith: Not sure if this might be your issue as it's a low power affair. I see that the transmitter can be seen across the valley from your road:

The other thing is that your aerial should be vertically polarised, that is elements upwards, for Ashbourne.
From your location Sutton Coldfield can be picked up and it is the same direction (albeit 6 degrees different). However, aerials for it should be horizontally polarised (elements flat and parallel with the ground).

Dick: Fortunately Rowridge uses low channels and Whitehawk high ones. A simple way to stop Rowridge being picked up during the automatic tuning scan is to run it with the aerial lead unplugged until it gets to 50%.

Peter P: When I said BBC should be C60, I was assuming that your aerial is directed east to Whitehawk Hill.
However, if it is on Rowridge (Isle of Wight) then 24 is correct.

Dick: Try removing the aerial plug from the Humax and holding it close (a centimetre or two away) whilst tuned to BBC1 on C60. You will need to run the scan with the aerial unplugged up to 50% to get it back on C60.
Unplug it with the signal strength screen on. Wait ten seconds or so for it to adjust and see if there is an improvement. The aim is to see if there is too much signal and holding it like that should loose some.
Another way of loosing some signal is, if it is a screwed together aerial plug, remove the metal outer part of the plug so that only the inner pin goes into the socket.
Or try using a set-top aerial if you have one as this will pick up less signal.
Not all equipment is the same and of the same sensitivity, so don't think that there is a fault with the Humax just because the Panasonic works fine.
