The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 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 Rowridge (Isle Of Wight, England) mast?

Christopher woodnutt :

As you haven't given a full postcode I've no idea what your normal predicted would be. If you are in a marginal area then work may give you a weak signal that your set thinks it's .
One thing that is never advised is retuning if you have no signal or badly pixelated pictures as this will often just clear your correct tuning. Did you perhaps do that thinking it would?

Planned Engineering work is periodically essential to ensure that you continue to have reliable reception especially when weather conditions become inclement. Work may be required on the etc on the and most such work can only be carried out when the weather is not very wet/windy.. It's also worth pointing out that it's a good 10 years since and a lot of main transmitters have been having extended essential engineering - items may need repair or replacement.

Another possibility is you may be suffering some which may only affect you when engineering work give you a weaker signal. If you provide a full postcode we might be able to advise further.

Fred Hotchen: I should have said my location is , Hampshire where is normally good on PSB muxes but marginal on some of the COM muxes, esp the one that has TPTV on it. Signal very down even on main Muxes and a lot of the time this evening, nothing at all.

You may or may not have noticed the Planned post for the week commencing 2/10/23, now on the previous page 2nd from last.
"Possible effect on TV week commencing 02/10/2023 Pixelation or flickering on some or all "
When you are in a weaker signal area, such work could involve using the reserve or operating at reduced for periods of time which may reduce you signal sufficiently it looks at though you have . Do NOT retune as this may just clear your correct tuning, you'll then have to retune again when signals are normal, possibly several times as you won't know when that might be.

From your comments about reception of the COM muxes and doing a random check in your area, I'd guess that the rods (or squashed Xs) on your aerial are horizontal.
transmits both horizontal and vertical polarisation but in HP the COM muxes are 50kW compared to the PSBs 200kW., however in Vertical polarisation they are also 200kW so re-orientating your aerial should significantly improve that reception BUT if you also happen to receive the Local mux, this is HP only, so you'd lose it BUT you aren't predicted to receive it although that doesn't mean you can't.

No faults are been currently reported, so it's the Planned Engineering currently affecting you.

Ashley: Davem: melvyn mouland: Fred Hotchen :

See my previous 2 posts just now as much of it could apply BUT also applicable to Fred Hotchen -
NOTE ALSO current weather conditions have been causing Tropospheric Ducting affecting much of the south coast and southern parts of the country on Saturday and more of the south of the country through Sunday. This causes interfering signals from distant transmitters in Europe or the UK to affect of your wanted signals. This can periodically last, seconds, minutes and sometimes much longer - Do NOT Retune.
There is nothing you can do about this apart from wait for conditions to change, or use online if available.

The BBC have issued warnings -
High pressure weather conditions impacting TV & Radio services - 6th October | Help receiving TV and radio

Christopher woodnutt this may also be affecting you but see previous reply.

Our TV has been interrupted since Saturday 7th of October, signal strength seems ok but signed keeps dropping very low or even out to 0.
My postcode is BH177HQ Dorset, the Arial is on the chimney stack and has never been an issue. Please could somebody tell Me if this is due to ongoing maintenance on the Isle of Wight
Many thanks
Daron

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.
