NJ, that's very strange as all the Sandy MUXs are around the same power, 170/180KW, and all their aerials would be similar. It's just possible that you have an aerial problem but that would be very rare; have you tried a different aerial with a higher gain?
Mike.

DouggieB: Apart from what KMJ,Derby has queried and with the answer to also being of interest to myself, I had a look at the manual for the LT26 earlier on today and as you will no doubt have noticed only the very basic info is given with regards to its tuning facilities, basically of course as there isn't any except the first time installation option.
As your problem could be suggestive of a software problem or that possibly a glitch of the existing software has taken place, or indeed that the set actually requires a software (firmware) update, I was searching about for some info on the model regarding these issues but failed to find anything mentioned, as its seemingly a bit of an oddball chassis with very little known about it, and so in view of this I can only advise that the best policy is for you to give Bush customer services a ring on 0845-604-0105 and ask to speak to their technical department and see what they come up with, as I don't feel that anything you can do will alter the situation if as you say, you have already carried out a reset, although just to double check I would carry out another one.

NJ: Of course you have to look at the situation along the lines that there hasn't really been any complaints from other residents in the Wisbech area as far as your type of problem is concerned, and so if it is being caused by some form of localised interference then just how local is it to you?
I fully appreciate that some people will so to say "suffer in silence", but if the problem was being caused by RF interference from afar it would be affecting a good deal more people than yourself, and so it would be prudent to suss out someone relatively local to yourself and who would be willing to carry out a channel check on request should you be experiencing any problems.

Brian, font of all knowledge, I once had, now misplaced a web site address which gave all the individual frequencies for each mux channel. (ie psb1 = ch27) but this site gave the actual frqencies for bbc1, bbc2 etc.
Any thoughts ?
regards Brian

I am trying to obtain the output from the UK Planning Model. I can see data on your website which is derived from the output of the UK Planning Model, but I dont seem to be able to access the actual data. According to a response to a recent parliamentary question (asked by Chi Onwurah and answered Mr Vaizey on 5th September 2012) such data should be available on this site. Could you please send me a link to the UK Planning Model output?

Tim Newton: Mr Vaizey actually mentioned the website "ukfree.tv" in his parliamentary response? Are you sure he wasn't referring to Ofcom?

Tim Newton: The model used on ukfree.tv is written by me, and is not that actual "UK Planning Model" because every time I have asked for it, I have been told it is a state secret, see Update on transmitter radiation patterns (BBC FOI request) | ukfree.tv - 10 years of independent, free digital TV advice for example.
The model used here on ukfree.tv is derrived from information provided by the OS, Ofcom and other bodies.
I am happy to provide anyone who wants it with the output of these calculations.

Thanks for the prompt reply. Apologies for my mistake, the site referenced in the question was actually the Digital UK site. Sounds like you are struggling with the same bureaucracy as I am.

Tim Newton: If you still want some data to work with, I can provide a dump for you.
