we are living in Godalming near Guildford and ordinarily can receive freeview tv, for most bbc and itv/ch4 channels.
however, virtually every friday night around midnight, for the past year or so, all channels except some bbc become 'low or no signal' and unreceivable - a situation that persists all weekend and often into the week. then all of a sudden they are back again, until the next weekend.
retuning the receiver makes matters much worse (even fewer channels) - so have given up trying. analogue (although not great reception either) has been our only fallback.
signal quality/strength is not always good where we are, but this seems periodic.
i am very worried that come the switch over we will be left with no tv at all having been totally forgotten about in the greater scheme of things by the broadcast/transmission companies.
there seems nowhere (except here perhaps?) to lodge our concerns.
anyone experienced similar/got any helpful advice?

Hello, one month ago I have installed an I-Can Easy HD Receiver with my existing roof aerial which I believe points to Crystal Palace. My post code is RH10 3TN. All scanned well, all channels fine. Today I've noticed NO SIGNAL for Channel 4 and ITV1, all others OK. Re-plugged, reset, etc..still no signal. I dont believe it's the box as al other channels are OK. What else can it be then ?

I have a fundamental question about Channel 4 and ITV : are these digital or analogue or both ??? My TV with Freeview does not list them in the All TV list but in a separate list called Analogue. Here I can see them in what I suspect it is analogue. My I-Can digital receiver lists them in All TV and sometime I see them and sometime I don't as per my previous post here. I suspect that what I see in the I-Can is digital channels ??? Two Freeview boxes ( my TV and the I-Can) both connected to same aerial and I see different things ??? Is this how it's going to be from April 2012 ??

ADRIAN: Perhaps you are in a marginal area for reception of ITV1, C4 etc on digital. The digital UK predictor certainly suggests that this one multiplex (group of programme channels) is "marginal" whereas the others are "good".
For this reason it might sometimes be available and sometimes not. Resetting and retuning is not good and should be avoided as now you have not got these services in your tuner's memory whereas if they were, you could switch over to number 3 to see if ITV1 was back.
The only time you should retune is when the services change channel when switchover occurs.
If there is a manual tune option on the device in question, then you need to manually tune to channel 22. If it doesn't pick anything up (or at least not a strong enough signal to provide a picture), then try again at a different time.

ADRIAN: Just in addition to that already fully explained by Dave Lindsay, but regarding your 9.38pm question on ITV & Ch4 both of these are presently available on analogue as well as digital from Crystal Palace and Reigate, but however wont be from April 18th when analogue transmissions cease to exist from both these sources.
Another point to remember regarding digital reception is that no two devices have exactly the same sensitivity, so even although both are connected to the same aerial its possible that a programme can be seen on one device but not the other.
This of course applies more to situations involving weaker signals from lower powered commercial muxes, but if it happens with a BBC channel then its an indication of a low level of signal being received.
Just as a finale, its only your TV thats capable of viewing analogue signals.

ADRIAN: There were engineering works at Crystal Palace last week, in preparation for switchover. Perhaps whatever it was has changed your reception slightly, but enough for your I-Can not to have enough signal to operate. The other possibility is that the signal level has dropped due to some atmospheric change and may change back.
If you have no joy manually tuning to channel 22 (using the digital part of your receiver), then from 7th March the power of Reigate's equivalent multiplex (which carries ITV1,ITV2,C4,C5 etc) will be increased ten-fold and it is on channel 21. Your aerial is the wrong polarisation (horizontal when it needs to be vertical for Reigate) and is pointing a bit in the wrong direction, but it might work to some degree. It is a try it and see sort of thing. It might be better than nothing until switchover on 18th April.
I tried looking online for a user manual for the I-CAN device, but have been unsuccessful. I was hoping to be more specific as to what it is you need to do (i.e. which buttons to press) having found out how it works. If you know of the manufacturer's name and/or website for it, then it might be useful to this end.

ADRIAN: Many thanks to both Dave and jb38 for taking the time to explain this to me.Really grateful for your help. I now plan to do nothing until the switchover, I'll deal with any problems after that. For reference the I-Can website is at : I-CAN from where the manual can be viewed/downloaded, which I did when I bought the box. (RH103TN)

ADRIAN: Thanks for the link. Looking at the instructions, there doesn't appear to be a manual tune option (or at least it isn't mentioned in the instructions).
