Mazbar: Thanks for that. It shows that there is no 'one solution' - you just have to narrow it down to what it might be!

Andy D: Signal strength 10? - look for 'too much of a good thing' for a start - it sounds like your tuner is being overloaded.

Anthony: You'll notice I said 'sat. systems are a different matter', and yes, its the limited bandwidth of Freeview which is currently a limiting factor.

chris: If you've tried two boxes with the same result - its not you although its worth swaping round an aerial cable, in case its that). Could be a problem with the communial aerial system, but nobody else has noticed it yet (dodgy aerial lead, plus existing problem = far less channels).

Terry carne: Have you actually checked signal strength on the muxes? If a channel is pixallating, that does not automatically mean the signal is too low (and hence a problem with the transmitter), but its well be too high. Your 27km from the transmitter, (providing your actually using the correct transmitter - retuning does no good, and might actually make things worse) and likely to get an excellent signal. That signal strength will vary slightly (mine does), but if its at the very top of the range, and then peaks, thats when you get a problem.
'No signal' can mean too high, not just too low. If it is too low, check your system. Even an inside aerial can have problems after 17 years - moisture, frayed cables, etc. And although it might be ok (ish) one day, it doesn't mean that problem has gone away.
Have a look back at comments where people insist the problem is the transmitter. In the bulk of cases (outside where a transmitter does have an actual fault or low power), its either that the signal is too high for them, or that the signal is too low, owing to a problem within their own system.

Terry carne: See 'too much of a good thing' on this website. Could be too high, could be too low - its always worth a check on signal strength.

LINDA LINDLEY: Check your manual - TV's and other boxes often have a timer built in, etc.

Dexter: I've got the same box, and while you can use it to control volume as well (the box has its own volume control), I just change the channels with the manhatten, and change the volume with the TV remote. Its just much easier, and no, it doesn't seem to be universal.

coach: Just because your getting breakup, dont assume its 'weak signal'. Actually check your signal strength. My manhattan HD box is getting a little bit of breakup on BBC2 HD - when I check, the signal strength is at 80%, thats causing the breakup. Its only just reaching that point once or twice, but its enough. Thats on Waltham, but you might be getting the same problem.

Mike: OK - I checked the postcode against digital UK - Coverage Checker - Detailed View - your 36km away, with indications of excellent signal on all mux's - so checking that signal stength check sounds like a good idea.
If you search for 'too much of a good thing' on the website, you can what the problem might be - if the signal is too high, in effect the tuner goes deaf, hence the breakup, etc. Worth looking at the other muxes as well, it could be that the others are close to the limit, but HD channels tend to get hit first.
