suzy,saxon@yahoo.com: High signal strength but accompanied with erratic quality is in most cases caused by factors outwith a persons household, although a bad joint (corroded) where the coax is terminated into the aerial box can also result in these symptoms being displayed, and so to eliminate any possibility of this being responsible for your problem if at all possible (as I realise sometimes it isnt!) I would try and check with a neighbour to find out if they are also being similarly affected "on the same channels".
I would though check that COM4 and COM5 (the transmitters associated with the programme channels mentioned) are being received from Sandy and not Crystal Palace, Sandy's COM4 being on mux Ch51 and COM5 being on Ch52, checking being relatively easy to do if you are still using the Humax 9150T.
Should though you discover that your neighbours are also experiencing similar problems to yourself (which I suspect will apply) then unfortunately there really isn't anything you can do, as its just one of the pitfalls of digital reception when located in a less than ideal area for reception.

I live in Milton Keynes and have a roof aerial pointing to the Sandy Heath transmitter. Multiplexer channels 24 and 27 are fine; however, about 6 days ago we lost the stations on multiplexer channels 48, 50 and 51.
Can you help with this problem?

suzy: If your Humax has stored C59 then that's COM5 from Oxford, programmes on this mux being Pick TV / Dave / Sky news etc.
This has likely happened during the last auto-tune you carried out, Sandy's C52 having been by-passed because it was being received at a very low level and where the next channel in line was stored which was Oxfords C59, Oxfords HD channel on C57 being ignored by your non HD box.
Even although the programmes on C59 are basically the same as C52 you should really be using C52, and so go into the channel edit facility and delete (11) Pick TV (also Dave 12) and follow this buy going into the tuning menu / manual tune and selecting C52, but "before" pressing search make a note of the strength / quality being indicated just in case its still very low, because if it is searching for the channel could well result in Pick TV & Dave not being seen in the programme guide.
The above method is really a short cut that sometimes works on Humax boxes, as by rights you should really scrub everything stored then manually tune in each of Sandy's mux channels one at a time.
Channels concerned being : 27 - 24 - 51 - 52 - 48.
As far as reception is concerned, as you have now managed to confirm that your neighbours are also being similarly affected then needless to say your problems are being caused by factors that are totally outwith your control, and so you have no real option but to wait and hope the situation does not take too long to settle down again.

jb38: i scrubbed the stations, did a retune with out the aerial in and cleared everything, ch52 wont pick up anything at all, probably why it keeps going to ch59 :( signal quality on ch52 zero strength is 65% on ch 59 the quality jumps from zero to 60 to up to 100 the strength is anything from 66 /67 % picture still breaks up and says things like this station is scrambled/blocked or no or bad signal

suzy: The reception of Ch52 is known to be problematic in certain since early last year, and indeed is only received by myself located in the Stamford area at a very low and erratic level to the extent of being non existent for much of the time, and yet Sandy's other muxes are indicating a stable signal of around 80% strength / 100% quality.
Needless to say there is nothing that can be done about the situation, which by me having carried out signal checks at various points to the East and West of my area suggesting that the problem is caused a notch in the masts radiation pattern.

suzy: Yes! as you would be flogging the proverbial dead horse by wasting time trying to find a solution to something that is outwith your control, and although in situations such as yours satellite (Freesat) would normally be the answer I think I recall you having mentioned in the past that this is mode is not an option for financial reasons.

I have had no television signal today and when I retune I only get 8 channels and none of them are BBC help please',! It's been getting worse over the last 3 to 4 weeks. I even swapped my digibox thinking it may be that but it's still the same. I live in Earls Barton.
