Seafordrose: Good to hear that the signal has returned. Were you successful in contacting any of the broadcasters of the stations concerned to report the loss of signal?
Atmospheric conditions have always affected radio and TV signals, this is not a new phenomenon and is not related to digital TV or radio technology. High temperatures combined with high atmospheric pressure cause electromagnetic waves to travel further than they would under normal conditions, which has the effect of causing signals from distant transmitters to be receivable which then cause interference with other signals being broadcast on the same frequency. With analogue TV/radio this would result in a worse picture than normal or hearing the sound from the distant transmission interrupting the transmission you were intending to receive and was particularly bad in some parts of the country during the summer months. With digital transmissions the interference can result in not enough signal being received for the tuner to successfully decode it which causes digital TVs to report no signal and digital radio stations to go silent.

Mrs S England: Try asking the broadcaster. This website is intended for technical help with reception problems and doesn't have any information on future TV schedules for any channel.

Laura Greaves: Freeview is received via a UHF aerial, a DAB aerial won't work as it is designed to receive a different frequency band. You can stream some channels over the internet if you have a smart TV or set top box with iPlayer etc, however there isn't any way to connect your TV's aerial input to your broadband to receive Freeview. I would suggest consulting a local aerial installer assuming your house doesn't have one already on the roof or in the loft.

Roy Jones: If you entered your postcode when prompted you will get your BBC 1 region on channel 101, BBC 2 on 102 and your ITV region on 103. Other BBC regions can be found at the end of the channel list.

Nick Anderson: Local TV is done on a tight budget, with broadcast patterns and power levels determined by Ofcom. I suspect you are referring to the Rowridge transmitter. The Solent local mux is only intended to cover Southampton/Portsmouth and the surrounding areas which should have good reception of all services with a horizontally polarised aerial, whereas the vertically polarised transmissions enable the COM4-6 muxes to broadcast at higher power in order to improve reception in areas further away from the transmitter which are not the target of the Solent local TV service.

David Watters: There has been no recent engineering work at Redruth in the last couple of weeks so nothing to suggest that anything has changed at the transmitter. Suggest you check out your own aerial system, start at the back of the TV and check all cables and connections then work your way back as far as you can safely access towards the aerial.

s m seaman & Steve O: Ridge Hill is a main transmitter serving over 250,000 homes. There are no faults listed and if the transmitter was off air there would be hundreds of complaints on this website and elsewhere. I suggest you both check your aerial systems, start at the back of the TV and check all cables and connectors and in tight then work your way back towards the aerial as far as you are able to safely access.

Graham: There is currently a transmitter engineering notice on the Chartham transmitter page that it is currently off air. Do not attempt to retune your TV or box as this will delete the channels which are already tuned. Once that transmitter is back on air your channels will return on their own.

Mark Fraser: Just above your post is a warning of possible service interruptions due to engineering works. There have been various other transmitter engineering warnings for Bluebell Hill over the last week or so.

MikeB: Based on the figure of 24.6Mbps from the article above there is sufficient capacity available on COM8 for a UHD channel right now, although of course that would only provide limited coverage. A switch to DVB-T2 would create enough capacity for a UHD channel to be broadcast one one of the PSB muxes making it available to virtually all of the country, presuming all Freeview lite transmitters continue to broadcast all 3 PSB muxes.
