I improved the antenna signal and I've got this:

As there is little sign, I asked another person to try and got this:

$femon -H
FE: Fujitsu mb86A20s (DVBT)
Problem retrieving frontend information: Operation not supported

and this:

[ 397.962795] mb86a20s: mb86a20s_read_status: val = 9, status = 0x1f
[ 397.962798] mb86a20s: mb86a20s_read_signal_strength:
[ 397.983108] mb86a20s: mb86a20s_read_signal_strength: signal strength = 
4096
[ 398.019975] mb86a20s: mb86a20s_read_status:
[ 398.020461] mb86a20s: mb86a20s_read_status: val = 9, status = 0x1f

I think these values ​​would have to watch TV, but no.

Suggestions are welcome

Thanks in advance

Alfredo
