As reported by Jean, the drxk statistics are not ok. While we don't have enough documentation about this device, it is possible to do better, by using what's available. In particular, the AZ6007 driver released a few years ago by Terratec, with served as the basis for the Kernel's driver has a version of the drxk driver with some statistics code on it. Import the needed bits from it, in order to provide a better set of statistics. After this change, the stats looks nicer, especially if used with a dvbv5 stats application: Lock (0x1f) Quality= Good Signal= 100.00% C/N= 3.55dB UCB= 135 postBER= 22.3x10^-6 PER= 0 Yet: - Signal is a relative measure. Didn't find a way to convert it to a real scale, and that would also depend on a proper tuner setting; - Carrier S/N ratio seems too low for DVB-C. I suspect that it is not being measured ok. However, this seems better than before.
