hello, last couple of nights on signal from waltham, have had pixilating and weak signal after 10pm, cant see that there is weather conditions to affect the 25kw and 10kw mux's? this is really annoying as the bbc and itv on 50kw mux's never affected by weather so far!

so is there work being carried out after 10pm? but if it is weather, why cant the signal be upped to 50kw, or at the very least when there is potential for atmospheric effect, temporarily up these 25kw and 10kw mux's to 50kw same as bbc and itv mux?

i have a loft ariel in central peterborough PE1 with no problem ever with bbc or itv on 50kw, waltham is my best bet, as low urban sprall in that direction.

to many high rises and brick walls to go through for sandy heath direction.

the only common denominator seems to be difference between mux's signal power at the transmitter?

It isn't just "weather conditions" that you may physically observe, it's "Tropospheric Ducting" that can occur under certain atmospheric conditions. Indeed there were some strong tropospheric conditions in different parts of the country Monday and Tuesday, and more predicted later in the week, but like weather forecasts, predictions can change.

The further you are from a transmitter (as well as how strong/weak the signals are) and the specific frequency will determine how likely interference from any distant transmitter (Europe or UK) might be at any given time.

If you are finding that this becomes a more frequent issue, (climate change isn't something anyone has direct control over) maybe best firstly to check your installation hasn't deteriorated in any way (aerial moved a bit, coax degraded, other objects in/on/around the loft or roof causing signal reception to be different), but then secondly to consider an improved aerial installation.
As you haven't provided a full postcode, I can't comment on the predicted reception at your location.

hello, chris,

thanks, i understand the atmospherics having this effect, but my annoyance is that the bbc, itv channel 4 mux's broadcast at 50kw, are never a problem (so the 50kw power seems to negate the effect of atmospherics?), so my installation is good. recently updated from a 5 element to a 12 element aerial which really improved signal strength.

but occasionally, when there is bad weather / atmospheric events between me and Waltham, the mux's broadcast at 25kw (really pick dave etc.), pixelate and breakup, while the 50kw bbc itv ch4 mux's remain fine.

and then the 10kw mux forces tv, is a problem more frequently.

my questions, being that the power of broadcast seems to be the common denominator. Is why cant the 25kw and 10kw mux's be broadcast at 50kw?, and if this isn't viable on a permanent basis like the bbc and itv mux's are, why cant the power be boosted when atmospheric events occur, to maintain seamless transmission across all programme channels? thanks.

I'm afraid that 50kW doesn't always guarantee good reception even if reasonably close.
Reported elsewhere, on Monday eg. at Ventnor I-O-W, reception of the BBCA mux was wiped out in the evening, and the D3&4 the following morning. There was good reception of some French muxes on other UHF channels.

Transmitters have always had to share frequencies, but they are generally allocated around the country so as not to cause problems in the predicted reception areas under normal conditions, and the same principle goes for coastal areas (eg. S. coast and France, E. coast and Belgium etc.) as well as the use of directional transmission where possible. The higher the power the more likely there'll be unwanted interference.

Because priority is given to ensuring that as much of the country as possible can receive the 3 PSB muxes, that has a limiting effect on available frequencies & powers for the other muxes. There are over 1100 transmitters in the UK, just over 80 are main transmitters, the rest are relays carrying just the 3 PSBs (apart from one welsh one which has SDN as well!). So at the end of the day, it's a bit of a balancing act and unfortunately there will be some locations that lose out on some muxes due to co-channel interference, good directional aerial installations may help in some places but not everywhere.

Turning up the power would just cause additional interference to many, so unfortunately that isn't an option.
You may happen to be in a poor spot for some of those COM muxes anyway.

It might be an idea to read the 3 or 4 posts just before yours.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
