    • Dvb-T2 Not Scanning & Dvb-C Not Saving All Scanned Channels


      Hi Everyone, my new dual tuner Dvb-C & T2 just arrive and was installed into my Dm7020Hdv2. I am using the latest Newnigma image. During testing I encounter the following issue,

      1. Set at Dvb-c – testing 1 tuner at a time, scanned channels about 95 but only able to save around 30
      2. Set at Dvb-T2- couldn’t scan for any channels. Tried changing the terrestrial.xml file at /etc/tuxbox to the one I had created for my location but it seem to continue reading the original terrestrial.xml which I do not know where is the another file located. I had checked and confirmed the file at /etc/tuxbox was change.

      Thanks very much

      Hi Joey, thanks for the reply.
      It’s not Germany but singapore, I had make a terrestrial.xml file but after copied over to /etc/tuxbox by over-riding the existing file, it didn’t work.

      Hi Gutemine, thanks for the reply.
      My T2 antenna does not have any electricity input and confirmed it is working as my other stb can scan and received channels.

      Best Regards to All

      First some stb output 5V automatically and there doesn't need to be an extra 5V input, this is sent out directly via the Coax cable.

      I know some indoor antennas have an extra USB Plug to steal power this way, but this doesn't mean that the antenna doesn't need the 5V if there is no such plug.

      Finally if the antenna is a fully passive one (like old Analoque TV antennas) it doesn#t hurt to send the 5V out via Coax either.

      At least Singapore seems to Broadcast their FTA DVB-T2 in H.264 otherwise a dm7020hd would be out of job ...

      An normally there is only 1-2 MUX sending all FTA channels, you can easily do a manual scan for these 2 frequencies without changing the terrestrial.xml at all.

      Regarding your DVB-C channel scanning problems - probably the missing ones are Radio channels, or data channels which will not show up in TV Bouquet. You may also use Frequencly lists from your cable provider to manually scan Frequencies of channels which were not found.

      Technically the dreanbox truies to find all used Frequencies of a cable provider but this is not perfect, especially if the cable signal is not strong an clean, then it will need some manual help ...

      Finally if you attach DVB-T2 antenna to one entry and DVB-C Cable to the second one you have to config the tuners accordingly only DreamOS boxes support activating both modes on both tuner entries and dynamically switching with a 5V switch.
      Bad mood, bad manners, bad Plugins, you have been warned :whistling:
