The symbol shows the location of the Winter Hill (Bolton, England) transmitter which serves 2,690,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Winter Hill (Bolton, England) mast?

I'm in Chester (CH3). Same problem lost all com 7 CH55 stations sometime Fri on all devices. Hard to believe in this day & age that atmospherics can cause such signal annihilation. As Dave says let's hope it clears up in few days.
Can't understand why no official comment from Freeview saying reason or have I missed it.......many people will be thinking it's their equipment, aerials etc & could go to unnecessary expense.

Com7 CH55 has returned here in Chester!! Just done manual retune for CH55......hey presto 14 channels reappeared . Was still nothing there when tried at 6pm, so has atmospherics changed since then?
Hope this is the case for everyone else who's posted on this subject.

Graham:

As per previous posts here it's "Tropospheric Ducting" around causing interference, see https://www.radioandtvhelp.co.uk/help-guides/television/effect-of-tropospheric-ducting-on-freeview for a simplistic explanation. It can be quite variable, come and go within seconds, minutes or hours. It has been particularly strong recently which can as you've discovered wipe out your reception. Climate change is likely to mean these sort of events could be more common.
Currently it may continue on and off for a day or two more.

It's best not to retune if you have no signal or badly pixellated signals as this can just clear correct tuning and you have to repeat the retune when conditions stabilise.

Can confirm CH55 back at normal levels here on the Fylde coast.

Was this posted here or elsewhere? Useful.

I have posted it in the past, but a lot of non-tech people just find it too confusing so I stick to just explaining the situation. There is another if you are interested http://tropo.f5len.org/forecasts-for-europe/

I've had a brand new Labgear triple element wideband aerial installed and reception is excellent on all the channels. Channel 55 MUX is just slightly less at 50% signal strength and 100% signal quality but is adequate for the DVB-T2 tuner on my LG Freeview HD / Freesat HD tv and pick up without problems. Channel is always slightly trickier to get right due to the slightly lower signal level transmitted on this MUX but it is being received at the very least.

Anthony:

The COM7 mux (C55) is transmitted as an SFN (Single Frequency Network) so signals from other transmitters with COM7 can create locations which can have less signal than others. Having 100% quality is the most important thing and based on my own experience you should be fine with ~50% strength although depending on location you may find it varies with some weather conditions. If there's Tropospheric Ducting, that might cause larger variations and in worst case - loss of quality (and/or signal). Other multiplexes may/may not be affected at the same time.

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.
