    Kaffeine > Digital TV > Television >Configure Television > Edit Scanfile shows me a text file named 'scanfile.dvb' as follows:

    Code:
    # this file is automatically generated from https://linuxtv.org/downloads/dtv-scan-tables
    [date]
    2019-03-14
    .
    .
    .    + many data lines . . .
    .
    The date, 2019-03-14, does seem older than the latest version online that is labelled 2019-09-29.

    I would unfortunately, not have a clue if I were missing any channels - It's only very recently (since I've switched fully over from Windows to Linux, and since I've been less busy day to day with non TV life) that I've been bothered at all about watching TV, so unlike many regular watchers I'm not really too aware of what should and shouldn't be present these days. Last time I regularly watched TV avidly, there were only 5 channels. I certainly am able to tune in a huge number of channels though, 135 all told including radio services.

    Looking inside the files I can see what I think is the section relevant to me - it's labelled with the name of my local transmitter:

    Code:
    my own 'scanfile.dvb':
    
    [dvb-t/uk-WinterHill]
    T 602000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE

    T 770000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
    T 778000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE

    T2 737833000 8MHz 2/3 NONE QAM256 32k 1/128 NONE 0
    T2 746000000 8MHz 2/3 NONE QAM256 32k 1/128 NONE 0
    Code:
    latest 'scantable.dvb' from https://linuxtv.org/downloads/dtv-scan-tables/kaffeine/
    
    [dvb-t/uk-WinterHill]
    T 602000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
    T 626000000 8MHz 3/4 NONE QPSK 8k 1/32 NONE
    T 698000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
    T 706000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
    T 770000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
    T 778000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
    T2 554000000 8MHz 2/3 NONE QAM256 32k 1/128 NONE 0
    T2 737833000 8MHz 2/3 NONE QAM256 32k 1/128 NONE 0
    T2 746000000 8MHz 2/3 NONE QAM256 32k 1/128 NONE 0
    If I'm right these are identical, so I guess I'm probably not actually missing anything?

    The updater button in Kaffeine just isn't working at the moment because of the filename difference, I guess..

    Yes, it seems that you already have the latest scanfile table

    I double checked my scanfile table [dvb-t/uk-Hannington] and I also have the latest info.

    Anyway, I'm not too bothered about additional TV channels, I would prefer better content from existing services.

    One other piece of info (if you are concerned) is that not all DVB scanning tools produce identical results.

    Scanning via Kaffeine produced 133 channels (TV & Radio)

    Scanning via Tvheadend produced 173 channels (TV & Radio)

    However, I've never tried to view all the channels so, it's certainly possible that some may be inaccessible.

    Best wishes
