Lee gammon: Your just 4km away from a transmitter, and 21km from the main one (click on DigitalUK link), so its highly likely your getting too much signal (nothing to do with the box).

I have a Bush TV with Freeview and a DigiHome DTR0207 Freeview TV Recorder with Twin Tuner. The aerial is connected to the DigiHome and a scart connection is then to the TV.
The transmitter used is Caradon Hill.
I have performed a full reset of Freeview on both devices but the channel lists differ in that I cannot manually or automatically tune the DigiHome to Frequencies 22, 24, 27, 31 or 39 so, for example, the DigiHome is missing Channels like Dave, truTV etc. in the 24 range.
Any thoughts on how to address this welcomed.

TR12 6SZ, with roof top aerial. Yesterday 7th March we were unable to tube into any Freeview channel or any DAB radio station. Were there any works being carried out to the transmitter?

Why has C22 gone to 0% signal and very broken stream? All other channels are fine

Ash: First of all, the notion of too much signal: This results in signal levels repeatedly dipping down, and can appear to the user as if there's too little signal, this being because the tuner is overwhelmed. Think if a bright light was shone in your eye; you'd automatically shut your eye and so even though the light is brighter you will "see" less light.

Now to the terrain plot:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


You may be able to see the top of the transmitter, "just" or "almost", this qualification being because it would appear that the terrain might be in the way or objects on the ground could be. If you click the "view map of" under the plot you will be given a line between the two points. The satellite image of Avery Way at Carkeel looks interesting. It's where Waitrose is and Avery Way looks like it could be added to in the future. Has this just happened? The OS map indicates a wind turbine on that industrial estate. Has another one been added?

as far as i know no new buildings have gone up at Avery Way and I have no idea about wind turbines

would my signal be too high considering on many other channels it is stable and between 50 and 100%?

tbh it is confusing, i would rather not call out a specialist but i fear that may be the only option

Ash: Well that is the thing. Why is there such a marked difference in reported strengths when you would think you reside in a very good signal area?

The other question to rule out is the possibility that a 4G base station has started up and is operating in the 800MHz band (C61 upwards). The organisation tasked with issues relating to television reception issues as a result is "at800".

I would give them a call and see if this could be the cause of your difficulty:

Contact us | Advice or general enquiries | at800

If it is then they will send out one filter per address.
