Hi All,

I use an USB DVB-T receiver. This works ok, but the snr meter at the bottom
of the screen is never filled more than a few pixels, no matter how good
the signal is. The problem with this receiver is that the snr figure never
goes above 0x00d0. Is there a way to adjust the scaling of the signal and
snr bars? I would like the snr bar to be fully filled when the figure is
0x00ff

Best regards,
Cedric
