I read the thread below and I have the same problems.
http://lists.gnu.org/archive/html/discuss-gnuradio/2006-05/msg00026.html
Here in Brazil these are the frequencies for valid analog TV channels
(VHF
/ PAL-M):
Mhz
54 - 60 Channel 2
66 - 70 Channel 4
82 - 88 Channel 6
186 - 182 Channel 9
210 - 216 Channel 13
I’ve tried many different things (specially decimation and gain) but I
still
can’t get any image.
The FM receiver example worked fine.
Can anybody help me??
Thanks a lot,
Augusto Pedroza
