I did the Freeview reset on Friday, why can I no longer receive Classic FM channel 731 and Sky Arts channel 11. Can you please restore then to terrestrial transmission. At 81 I enjoy these channels.

Peter Flannery:
The channels have not been removed, you may just not be receiving them. This is an independent technical helpsite, so we'll provide advice on how to hopefully resolve your problem.
There has been some quite variable weather related Tropospheric Ducting in recent days which can affect reception because of interference being received from more distant transmitters in Europe or the UK - not all multiplexes are necessarily affected, but this isn't normally sustained for any lengthy periods, but if present during automatic retunes it can cause the sort of problem you've seen.
Both Classic FM LCN731 and Sky Arts LCN11 are carried on the ArqA/COM5 multiplex (a group of channels). If you are currently not getting the multiplex you will most likely be missing a number of other channels on ArqA, such as LCNs 12, 19, 31, 36, 40, 43, 45, 47 and quite a few more including a number of radio stations.
To restore it you'll be best by doing a MANUAL tune in your TV tuning section for UHF channel C22 which is the one for ArqA/COM5 at Rowridge. If for some reason you do not normally receive Rowridge but another transmitter,, please provide a full postcode so we can check.

Julia Chalmers:
Apart from this being an independent technical help-site, even the transmitter owners can't "up the signal", maximum transmitter powers are fixed by various international agreements.
In case you hadn't spotted, the post before yours lists the transmitter as being on Planned Engineering which could be the cause of your problems. However, you are 87km from Rowridge which although predicted to give you better reception than the closer Whitehawk Hill transmitter (even if that is only 4km away), a lot will depend on your precise location and any very local obstructions - trees, other buildings etc.
If you aerial is pointing at Rowridge, for the best reception it should have its rods (or squashed Xs) vertical and pointing at compass bearing 256 degrees that's almost 8 degrees west of WSW.
Do check in your TV Tuning section that you are correctly tuned to Rowridge's UHF channels as noted at the top of the page. If you happened to retune under adverse conditions (low/no signal due to weather, maintenance, interference etc) you might pick up Whitehawk Hill etc.
Do you have a smart TV & Broadband? If so, you may be better watching Wimbledon on iPlayer if signals are variable at present.

hi
i use Linux , Kaffeine and VLC software, to receive my TV from Rowridge.
using VLC i can tune in to any individual Mux using its frequency value input to VLCs capture device option
when i do this i get way way more stations than are available on Freeview.
however they seem to be off broadcast or encoded.. i dont know which.
what are all these extraneous channels and who can see them?
please help me sleep at night as i am experiencing FOMO symptoms.....
thanks tony

tony archer: Some of them may be part time channels such as placeholder +1s or adult channels which broadcast for a few hours overnight. You might also be seeing entries for the portals which link to streaming channels, I've no idea if VLC is able to open them directly as I've never tried, although if you search online it may be possible to find the URL of the stream which can be played in VLC.

At 12 minutes past 6 each evening we lose all channels on Ch 27 mux. Manual tuning shows 74% Signal Strength, 0% Signal Quality. Any ideas? Alan

Alan : This has to be something in your local area, some electrical appliance or device, emitting interference. It must also be one which is timed, hence it always occurs at the same time.
Use a battery-powered AM radio to track down the source. Tune away from a station. Have the radio turned on before the interference occurs and the TV on, tuned to a channel on the C27 mux. You might hear the noise begin on the radio at the same time the quality of the TV signal goes to zero. You then know you are hearing the source that is knocking out the TV. Move around with the radio in effort to locate the source. Be aware that an AM radio doesn't use a pull-up whip antenna, as with FM. Instead, it uses a ferrite rod inside the set. This is directional and you can use this to your advantage when locating the source, but understand how it works first:
The aerial is most sensitive perpendicular to the set. It is least sensitive at each end. What this means is if you tune in to a station (on AM) then spin the radio round, keeping it horizontal, you will find that the audio goes fainter/weaker and stronger as you rotate. When it is at its strongest you have the radio facing or with its back to the source (the transmitter). When you rotate it 90 (keeping it horizontal), the sound will go to its lowest/weakest. The signal is therefore coming from the direction at one ends of the set. Come to understand this and use the same technique to locate the source. Bear in mind that it could be above you, either directly above or diagonally above.
How long does the break in reception go on for? The longer, the better because it gives longer to find the source.
I am reminded of a three-way port valve that switched the water flow between hot water and central heating, or both. When it was activated it would obliterate reception of an FM station for 20 seconds or so.

Steve Donaldson: See this video of a radio ham tracking a source of interference in his house. Early on he shows how rotating the radio to where the sound is at is lowest/least means that the source is in a direction that one or other end of the set is pointing:
Tracking Interference Using A Portable AM Radio With Ferrite Antenna - YouTube
Having surveyed a number of locations, he triangulated the location of the source.
Bear in mind that the noise could be emanating from something at a neighbour's.
