Thema: Änderg von DVB-T2 Kanälen

Hallo,

FYI, als Hinweis, ich habe gestern einen Sendersuchlauf für DVB-T2 im Rhein/Main-Gebiet gemacht.
Dieser war nur zum Teil erfolgreich, d.h. es wurden nur 16 von 40+ Sendern gefunden.

Ursache für das Problem war das die voreingestellten Kanäle aufgrund einer Änderung von einigen Kanälen/Transpondern zum 28.11 nicht mehr gestimmt haben.

Aus 39 wurde 42
Aus 37 wurde 31
Aus 54 wurde 25
Aus 59 wurde 47

Ich weiss nicht in wie weit dies relevant für das Entwicklungsteam ist. Vielleicht muss die Änderung in einer neuen OpenNFR Version eingepflegt werden ?
Bis dann Ciao Celt

Ich hatte ein ähnliches Problem mit meinem OS Mega, im OpenATV-Image. Die vordefinierten Kanäle stimmten dort auch nicht und ich habe dann einen vollen Suchlauf über alle Kanäle gestartet. Das dauert nicht allzu lange und damit werden alle Sender gefunden. Da es sehr mühselig war, den passenden Eintrag in der Kanalliste zu finden, habe ich im Nachgang die Datei ./etc/terrestrial.xml angepasst. Vielleicht hilft das Beispiel auch hier weiter:
