Dual s2 device missing some transponders at blindscan
« am: Februar 16, 2021, 07:03:03 Nachmittag »
Hello,
I tried blind scan feature on skytv dual device there are some missing transponders that device can't found
my old M88CS8001-S based STB was finding that missing transponders on blindscan

11053.00   H   DVB-S   QPSK   8000 3/4
12729.00   V   DVB-S2   8PSK   30000 2/3

device can lock both of transponders but can't find in blindscan

The Blindscan is running some algorithm for searching the 950-2150 band, a real scan should still try to use the NIT scan. Applications are usually using tables as well. That's nothing to worry about.
You might try to tune to one (or some of those transponders and run a nitscan)
/opt/bin/mediaclient --nitscan /dev/dvb/adapter0/dvr0
Failure is a good thing! I'll fix it

nitscan usually take much more time than blindscan but still i prefer nitscan over blindscan too
thanks
