Derek post your postcode here so we can see what strengths and directions involved.
What aerial are you using?
You may have the channels you want in the 800s (usually) and be able to move them to 101/2/3 etc.
Freesat lets you pick whatever services you like, Automatically if yyou give it a postcode for where you want.

Matt: All around the Downham Market area (should you be in it) its possible to pick up signals from both Sandy and Belmont with roughly the same strength in various areas and you might have picked up a mixture of both during a re-tune, and so "if" BBC Look East is your news service then its coming from Sandy on mux Ch27, and so the three commercial mux channels that match it are: 51 - 52 - 48.
To check this, select Dave(11) and carry out a signal check on it for purposes of seeing what channel number is associated with the indication, which of course should be mux Ch52, if 53 its from Belmont.
Carry out the same test on Quest(38) and in that case its should be mux Ch51 but 30 if from Belmont, finally select Yesterday(12) which should be mux Ch48 but 60 if Belmont.
If you find that that's what's happened then you will require to manually tune in Sandy's six mux channels one at a time, these being :27 - 24 - 21(HD) - 51 - 52 - 48
Should though you have Look North as the BBC news service then that's from Belmont, and in that case the six mux channels used are: 22 - 25 - 28(HD) - 30 - 53 - 60

Matt: If you do find it necessary to use manual tuning procedure then everything stored should first of all be deleted by carrying out a "factory reset" on your TV or box, this sometimes called "default setting", but if you see "first time tune" or whatever you can use that instead provided it offers a manual scan option, as some devices don't.
Any problem in carrying this out come back with the model number of whatever you are using.

Stephen / Dave: My Postcode is LU1 4AL This is about the highest point due south of Luton. I have just remembered that one of the reasons for pointing at London was that there was a broadcast repeater so close and so strong that on analogue it caused ghosting when pointing at Sandy Heath. At least that's how I remeber it.
I'm using a Humax PVR9200T that also now sometimes fails to start programed recordings even though I have done multiple re-tunes. Everytime I do a retune it wipes out all the planned rcordings.
As far as the arial is concerned this TV is in my Study upstairs and has its own loft arial which is a single reflector. I can't remember how many elements it has but its a reasonable size.
I will see what manual tuning I can do when its finished recording.

You seem to have a choice of fairly strong signals - which may be your problem! NB link above is conservative about what aerial you need.
If you have other aerials try the kit elsewhere.
May well be worth paying a LOCAL aerial man for his local knowledge of your many options

Tried everything you said jb38, but i only have 16 stations now (not all 16 are even stable) i checked and my stations i have are coming from Sandy Heath. I went from having all stations perfectly to having just 16 semi stable ones after the May 8th switchover.
Im 2 miles away from Downham Market.

Matt you seem to have a lot of options - need a full postcode for better data.
You should be able to work out what you are getting from the channels numbers and the muxes they are on.
What sort of aerials

Hi again jb38
I've been reading the new posts on this forum regularly and have been thinking about my own situation too, and I agree entirely with Ian's post on Friday 18 May 2012 4:06PM and would like to see Sandy Heath revert back to the settings it had before the upgrade on 9th May - not that this will happen (!), but I just wondered is there anyone 'official' who is responsible for the upgrades and who we can contact directly to raise our concerns about the loss of numerous FREEVIEW channels?
Perhaps if enough people who have been having problems since 9th May and have posted on this forum complain to the appropriate parties concerned, they may do something about it.
any information you are able to give would be very greatly appreciated.
many thanks as always
kindest regards
Lisa :-).

Hi Stephen P. Im picking up stations on (27 - 24 - 21)
My postcode is
I have no idea what my ariel is, but what i do know is that my ariel works fine because i was picking up all the stations no problem before the May 8th switchover, so this is nothing to do with my set up this end! lol
Im not bein told i have to spend even more money, this whole digital switchover has been an exspensive balls up that we were forced to pay for.
It seems others are losing lots of stations after May the 8th too huh?
So my options are?
