Hi, new to forum, but not to MP.

Have same issue with MP1 (1.19.0) and MP2 (2.1.3).

Cannot find DVB-T2 TV channels on TV server on MP1 and TV+Radio channels on MP2

1. From Israel, lives in place where 2 DVB-T2 transmitters are available: 562Mhz and 530 Mhz.
2. On DVB-T2 freq, found radio channels, not TV channels on MP1 (no radio/TV channels on MP2)
3. Desktop PC with Win10/64bit and TBS 6281SE card.
4. No signal issue - signal is 100% in all frequencies (through MP TV server bar and also thru ScanChannelsBDA_UK utility). Also, on other room I have signal of DVB-T2 on my TV)
5. DVB-T is fine (both TV and radio)

    On DVB-T2 freq, found radio channels, not TV channels
    I don't know anything about MP's "TV Server", but I do use DVB-T and DVB-T2 to receive TV and radio in the UK. Looking at your symptoms, I would ask this:

    Are you 110% sure that you are receiving radio channels from the DVB-T2 MUXes?

    If you are not receiving radio from the DVB-T2 MUXes, the problem is likely to be that TV Server is scanning the wrong frequencies. TV Server can scan the entire spectrum, but its default action is to scan only those frequencies defined in an XML file (this is much quicker). If that file specifies the wrong frequencies, TV Server will scan the wrong frequencies, and not find any channels on those frequencies.

    To check if your radio channels are in fact coming from the DVB-T MUXes (and not DVB-T2):

    (1) Start "TV Server Configuration".
    (2) Click "Radio Channels" in the left side menu.
    (3) In the list, click one of the main radio channels for your region.
    (4) Click the "Edit" button below the list.
    (5) On the panel that appears, scroll to the right to view the last column. This is the frequency of the MUX that contains that channel. Is this a DVB-T frequency, or a DVB-T2 frequency?
    (6) If it is a DVB-T frequency, check several other radio channels to see if you can find one that has a DVB-T2 frequency.
    (7) If all radio channels have DVB-T frequencies, your problem is probably incorrect data in the XML file.

    The XML file can be found in:

    C:\ProgramData\Team MediaPortal\MediaPortal TV Server\TuningParameters\dvbt\

    and there are four files for Israel: "All Regions", "Central", "North", and "South". The "All Regions" file defines two MUXes, but the others define only one MUX each. None of them specify either of the two DVB-T2 frequencies that you mentioned in your post. So modify the relevant file to add the missing entries for the two DVB-T2 MUXes and rescan using TV Server. Note: this is MP 1.18; I don't know whether MP 1.19 has the missing frequencies.

    Once you have found the correct frequencies, you might like to submit your updated XML file for inclusion in the next release of MP.

    1. From Israel, lives in place where 2 DVB-T2 transmitters are available: 562Mhz and 530 Mhz.
    According to this map, the frequencies are either 538 and 562 (north) or 514 and 530 (central and south). Can you copy the files from the attachment to "C:\ProgramData\Team MediaPortal\MediaPortal TV Server\TuningParameters\dvbt\" (MP2 may have a different path) and run another scan?

    I have the same problem. I modified the xml file with the new frequencies -> C:\ProgramData\Team MediaPortal\MediaPortal TV Server\TuningParameters\dvbt\Hungary.Budapest.xml

    I found the new frequencies on the website of MindigTV (Antenna Hungaria): https://mindigtv.hu/mindigtvextra/tv/technikai-informaciok-1/frekvenciatablazat-2/

    It tells us that these frequencies are avaliable from 1st April 2020.

    I use a miniPC (motherboard: ASRock Q1900DC-ITX ) to let run MediaPortal (1), and use the Astrometa DVB-T/T2/C tuner. So I assume it should work, but it does not. It finds only the free DVB-T channels:

    1tp- 746125 8:No signal
    2tp- 770125 8:No signal
    3tp- 610125 8:No signal

    Can you help me?

    From the web page that you linked, the Budapest area should be able to receive 5 MUXes (if I have understood it correctly). However, your post shows 8 MUXes were scanned, but only 3 MUXes were detected. Curiously, one of the MUXes that was detected (554000) is not listed as one of the 5 MUXes for Budapest shown on the web page. :confused:

    Are you sure that the web page shows the current MUXes for your location?
    Are you located somewhere other than Budapest?
    (I am wondering if I am looking at the correct line in the table.)

    One way to find the channels would be to scan all frequencies. This may seem like a strange suggestion, but select "Thailand" as the country and "All Regions" as the region. I have suggested this because it contains all frequencies and uses the same value for the offset as Hungary (125); some other countries (such as the UK) use 167 for the offset. However be warned, scanning all frequencies is time consuming! I have never tried this myself, but it might take 15-30 minutes to perform a complete scan (that is a guess!).

    Főnix TV is a local channel and is independent from MindigTV.
    As you can see the first 2 MUX's techn. coloumn is DVB-T which is successfully detected. The other 3 MUX is DVB-T2 and there is no signal altought I use DVB-T2 usb tuner, the same like this one: USB 2.0 numerique DVB-T / T2 SDR + DAB + FM HDTV TV de recepteur de Tuner O6N2 | eBay

    I cannot be sure until someone else from Budapest verifies it. But the site tells us it's used since 1st of April this year.
    I'm located in Budapest, I'm sure you are looking the correct lines in the table.

    A: 498 / 24 (found 4 on this)
    B: 634 / 41 (found 9 on this)
    No signal on those:
    C: 610 / 38
    D: 538 / 29
    E: 578 / 34

    I tried to scan as you suggested for all frequencies, Thailand + All regions. Results:

    1tp- 474125 8:No signal
    2tp- 482125 8:No signal
