hi all
i am trying to scan for dvb-t channels with this blody Artec T1 with no
luck (the error message at the bottom of this mail) and googling around, i
found i was not the only one with this problem, and many cinergyT2 users
had this very problem. It has been solved for them using a simple trick.
In cynergy2t.c, someone noticed this :
.frequency_min = 174000000,
.frequency_max = 862000000,
.frequency_stepsize = 166667,
He rounded the stepsize to 167000, and added 167000 to each frequency to
scan. (I.e. : in fr-Rouen, "T 538000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE"
became " T 538167000 8MHz 2/3 NONE QAM64 8k 1/32 NONE ") and then scanning
worked just fine.
Of course, i tried the same trick, and of course it didn't work. I am not
a developper AT ALL, i don't understand anything in technical stuffs, but
i think that, maybe, such a thing is also possible with my device. The
point is : where is the equivalent to the frequency_stepsize value for my
device (dmesg output at the end of the mail)?
Best regards
alan.
