    Hi Martin
    Signal Quality is 100% on all channels.The ones that have picture break up are 46/48% Strength (Ch55,746000KHz,8MHz,32K,1/16(DVB-T2))
    RE recordings...the box is working fine just the 3 channels are unwatchable sometimes.
    They are watchable while viewing thru TV only.
    My best up is Aerial> Humax> TV..Most of the time I watch Live TV and use box to record.If I record BBC4 HD it,s unwatchable.

    That is National COM 7 and as already been stated is on low power. I can lose these channels every time we get a high pressure inversion. The Humax tuners do return a lower power value than the TV and it tends to be the Humax that drops the channels.

    True but the Freeview coverage checker thinks he should be able to get a good signal (S 99% M100%). What does it say for your location?

    Now 92 100 Final by 2025 92 100. The TV can and does return similar values with low pressure/ordinary weather patterns, but will drop off somewhat with high pressure. However I have yet to see those values via any Humax box e.g. 2000T, DTR 2100 and the Aura. All the Humax kit struggles to hold onto COM7 when weather pressure is high.

    Hi,
    Was speaking with my local TV Engineer and he has told me that these 3 channels are transmitted on a higher frequency (HD) and the diplexer won't let them through.
    Have to watch these in SD.
    Thanks for the input.
    Cheers

    Yes that makes sense (not that I know anything about the frequency limitations of diplexers); thanks for coming back with that extra information.
