Signal too weak - but it's almost 100%

    Hey,

    Loving this PVR - when I was using the youview box I had an attenuator attached bringing the signal down from 100% to around 65% (on the advice of Youview as some channels had disappeared). I am getting occasional messages on screen saying the channel signal is too week then the picture appears, this is mainly the HD channels (particularly the ones on COM 7). I have tried popping the attenuator back in situ with not much luck. Signal strength is around 98-100% with similar for the quality.

    Any advice?

    Rick.

    Com 7 and Com 8 are transmitted using lower power than the other Mux.

    Can you first check that you aren't receiving from multiple transmitters (Channels over 800 in the epg).

    Next get an estimate as to your local reception conditions. Use your postcode here, and select detailed view.

    No channels over 800 being received and it appears that I am potentially receiving signals from multiple transmitters (I can inbox you the direct link if that helps?)

    Rick.

    Channels over 800 means you are receiving multiple transmitters. When an auto scan finds duplicates it stores them at 800 up. This is clearly not an issue.

    A screengrab from the DTG reception site would be of interest.

    It won't let me submit them - have uploaded them here:

    You must be using Oxford (only one with Com 7). If you look at the colours the MUX in green shows good reception, com 7 and Com 8 are much weaker. Did you actually tune to a COM 7 channel (107 for instance) before checking signal strength and quality ?

    If you open manual tune, enter channel 31 and select DVB-T2 you should see the real reception figures.

    A remotely powered masthead amp installed as close to the aerial as possible (in the loft will do) or a higher gain aerial might resolve the issue.

    Tuning into Ch 107 and bringing up the signal test gives me tuner 1 with 100% strength and 100% quality.

    Doing as you said and searching using your method brings up zero channels and strength and quality at 0%. This is the screen before I do the manual search:

    I live in flats with a shared aerial, so your suggestion re. a remotely powered masthead amp isn't possible. How can the signal strength and quality both be 100% (such as on ch 107) yet cause intermittent problems? It's confusing! Incidentally I have none of these problems when I watch freeview on my smart tv.

    To clarify, what channel number is displayed on the signal test page when viewing 107

    Home
    Settings
    Channel Settings
    Signal Test.
