Mrs Oblington

60% quality is on the lower edge of what may be acceptable so could give problems. Signal strnegth is imprtant too and should be between 60 and 80% but a higher figure for quality is preferred.

Atmospheric conditions. There's nothing anyone can do about how the atmospheric conditions affect transmission distances.

Are there any proposals to increase the power on the com 7 Multiplex to the same level as the PSB & com 4-6? Reception I get on com 7 Channels is variable at times, pixellation & drop out.
I have tried pointing the aerial to Crystal Palace but with much the same effect. I am limited to a loft aerial and amplifier which does not help. My postcode is CM18-6SR

Presents no real problem as I can watch BBC News & BBC 4 HD on my Freesat.

Since recent channel reorg on sandy heath I get message "due to technical problem service required not available. Try later" when selecting HD channel. Channel works but have to press yellow button to remove message. Manufacturer states message is from freebies not TV. Any suggestion?

josh : No.

They block UHF channels 61 to 69, which are those used by 4G base stations in the 800MHz band and which are just above that of TV frequencies.
