Tim: Unfortunately this could indicate that your TV or box is not capable of responding to the changed transmission mode of 8K that started at the same time as the high power switchover on this particular channel, with the ITV etc doing likewise on the 31st.
It should tell you in the manual of whatever you are using whether it can or not, this seen in the specification section, if only 2K is indicated then thats the problem.
If you care to come back with the model of device you are using, I (or someone anyway) might be able to check on it, but it should be said that if this is the cause, then in many cases its not rectifiable.

Alan Clarke: Just to somewhat back up what has been mentioned by all, first thing this morning I tried a test on Ch28 using a small amplified log aerial that I carry around with my gear, receiving ITV1 HD from Belmont with a perfectly stable picture.
The other HD channels were too low to resolve a picture, but at 50 odd miles away on an temporarily positioned aerial at about 18 feet from the ground, this is not entirely an unexpected result.

Lyn Duckworth: To put it simply, if anyone requires to use a Sky boxes analogue RF output to feed Sky channels to more than one room, then what they require to do is split the RF output from the Sky box via a two way (or more) powered splitter, the lead from the Sky box going into the splitters common input and with each of the two outputs going to the analogue, or dual /triple standard TV's as required.
However as you are using a magic eye on one of the TV's the splitter you purchase will have to be the type advertised as having a "DC by-pass" facility, as if it hasn't the eye wont work, but the plus point with this type of splitter is that you can also use a magic eye on the second TV should it be required at some time.
If though you have no intention of ever doing that, then a standard powered splitter would suffice, but with it being used "after" the magic eye, as if it was before it the magic eye wouldn't work.
This being said taking it that your Freesat TV does have the capability of analogue reception, and as such has a standard aerial input socket as well as the dish one.

danny: If you are referring to you presently feeding the normal roof / loft aerial into the Sky boxes RF input, then its analogue RF output being fed into an amplifier / splitter to feed analogue TV's in other rooms, then no provided a few precautions are taken when adding the Freeview box into the equation.
This being necessary to ensure that the analogue output from the Freeview boxes modulator (making sure it has one) isn't clashing with the RF output channel used on the Sky box. Then to complicate it further making sure that neither of the two RF outputs clash with the Freeview channels being received, which unable to advise on as your location is unknown, hence the Mux transmitter channels applicable in your area.

bruce moore: Indications suggest that you could be received your TV from more than one source, and if its Waltham then a technical aspect concerning the new transmission mode now used on the BBC Mux could possibly be the problem, and which will also apply to ITV1 etc at the end of the month at the second stage of the switchover.
However, that said, this possible snag can be verified or not if you can indicate where you are receiving your signal from.

jean brown: As you are only 8 miles away from Belmont your TV / box could be suffering from signal overloading problems, this showing up in various ways, so if by any chance your aerial uses a booster then it must be removed, however if it hasn't then you may have to add an attenuator in line with your equipments aerial socket, these obtainable for just a few pounds from any good TV shop.
A good test for overload problems is to try a set top type of aerial, as if the problem you are having stops then it confirms the cause of the problem.

Graham : Yes! as all you require to do apart from making sure of the alignment, is to fit it with a new LNB, which to be prudent as far as future additional equipment is concerned (e.g: Freesat twin tuner PVR) should really be a quad version, something which can be purchased complete with arm adaptors (if necessary) for under £10.00 from a variety of e-bay sellers.

Neil: Yes quite correct Neil, as many people including myself, use quad blocks to feed a normal Sky box on one of the outputs, and Freesat devices (TV / PVR's) on the other three.

danny: Referring to advice given, should what was mentioned be correct and you are going to daisy chain the Sky box with the Freeview one, then make sure that you plug the normal aerial into the Freeview box first, then from the Freeview boxes RF output into the Sky boxes aerial input, then from its RF output to your splitter / amp.
I say this as its good policy to give any Freeview device the best signal, which it wouldn't be if going first of all through the Sky box.

Alan Clarke: Taking it that you are using Belmont, which is transmitting HD on Mux Ch28, "no signal" can indicate that your TV is only HD ready meaning it can show HD from an external HDMI input, but it doesnt necessarily mean that it can receive it.
Look at your TV's manual technical spec, if it can receive HD it should state on the tuner info DVB-T2 capable, if its only HD ready it will be DVB-T, meaning that its tuner cannot receive HD, only normal SD.
This is something that many people are getting caught out with.
