I'm not as expertised as others who post on this site but I can absolutely say that one or more muxes can and are effected by weather conditions. As note of interest on Saturday night I was watching Yorkshire tv with perfect stability here in south west Hertfordshire at a distant of a 100 miles plus for an hour. I have problems with channel 22 as its one of the weaker muxes and I live about 20 miles from Crystal Palace. After switchover I'm pretty sure these problems will stop. This site is a very valuable source of free information and I do get annoyed with people disbelieving the information given here. The information here is much better than some advice I have been given by more so called professional bodies.

Tim: Yes, you are quite correct regarding the atmospheric conditions (high pressure) that is presently applying, and which is responsible for disrupting television reception across large areas in the UK, although apparently this high pressure "inversion" effect problem mainly affecting South of the border as there are at present anyway, very little complaints about reception difficulties being made from the Scottish regions.
I also agree that come April the 18th when Crystal Palace is fully switched over to high powered operation that most complaints of reception difficulties from that station will virtually vanish, that said though, I do fully expect that there is going to be quite a number of new complaints springing up due to signal overloading problems causing instability in TV and boxes tuners, the symptoms of being "exactly" the same as that of a weak signal, although a lot easier to cure by the addition of an attenuator in line with the receiving equipments aerial sockets.
Thank you also for your most complimentary comments regarding the site.

You have a very good prediction for crystal palace (london), so is you aerial in good condition and all the cables connected correctly? If so, it could be propagation wiping out the channels you mention.

Is ArqB going to be (post-DSO) on C28 or C28- please ?
According to Ofcom, it's going to be C28-

Matthew Hopkins: Digital UK Tradeview predictor concurs that it will be 28-

Matthew Hopkins, Dave Lindsay: Chances are this is to ensure that the suggested local TV service on C29 has a full 8 MHz. It will probably actually be C29-. The issue is caused by BBC B having a negative offset - which is to stay out of the way of whatever service ultimately ends up bordering at 550 MHz (i.e. the bottom of C31).
Nearly all receivers will automatically detect and apply the offset even if manually tuned. There are a number of receivers, based on Vestel's T810 chassis, that can't handle negative offsets in 8K mode, if they haven't had an update. See Unofficial Vestel PVR Information (UK) - T810 Freeview Recorder for a list of known models.

I've made this comment elsewhere, but it's probably worth repeating. I asked in a local TV dealer in Surrey if they were also experiencing poor digital reception at the moment. Their answer was "of course we are and we've been told by a rep that the reason is the Crystal Palace transmitter power output has been reduced whilst they are making modifications prior to DSO". I guess if you are working on an aerial with 20kW of RF, then so would you. We've had high pressure and inversions many times over the last 5 years but we have always maintained a good signal. Since early February, whilst they have been working on the transmitter, poor atmospherics have combined with lower signals, hence loss of reception on several multiplexes. Here's to the 4th April and 200kW.

Authoritative sources on WWW appear to indicate the forced switch-off of analogue and consequent hassle and expense for people re digital was caused by an oversight of the government project team in allocating bandwidth and frequencies for the olympics and so forth to overseas media and security purposes. The trusty old analogue gets given to them and the fee paying public get aeroplane disturbance, high pressure "inversion" and a headache if someone uses DIY tools between the transmitter and aerial.
Then of course you could catch analogue virtually anywhere but digital needs a full on unfettered path or it's patchwork city on the tv screen.
Then there was a paper written by the scottish parliament outlining how lucrative digital would be for politics and councils.
I do hope the powers that be will solve all the issues so everyone will be able to enjoy the tv/radio as enjoyed during the rusty old but fully working analogue days.

hi...i run my freeview thru a humax 9200t box and have lost count of how many times i have had to retune in last 2 weeks..itv ,channel 4,channel 5 were impossible to get here (harlow) lets hope after the 18th of april it gets better,my rx20 aerial is pointing to crystal palace but i think sandy heath may have been a better option...Here in harlow the crap virgin media are only giving the 5 usual channels thru their pipelines to homes...how do they get away with it!! they should be FORCED by government to give all freeview channels,They took over from NTL ..WHAT a shambles..i blame the councils for letting these companies do what they want

Attenuator.
Currently have masthead amp.
Assuming after 18th, too much signal, which make attenuator would be best suited for use at at the digibox input end. Don't want to mess around with aerial end if possible. Or if I cut off the power to the mast head amp, will the signal "pass though" un-amplified so that an attenuator would not be necessary?
Tks
