Please send me a proper patch if you have any success with this.

Hi Klaus,
I have not yet tested this, but the below code should work. I assume the receiver has a snr of 0x0000 to 0x00ff based on the following datapoints: 0x0080 almost never lock, unwatchable 0x0090 almost always lock, lots of disturbances 0x00A0 always lock, almost never disturbances 0x00D0 best signal ever received.
$ lsusb Bus 001 Device 004: ID 2013:0245 PCTV Systems PCTV 73ESE
uint16_t MaxSnr = 0xFFFF; // Let's assume the default is using the entire range. // Use the subsystemId to identify individual devices in case they need // special treatment to map their Snr value into the range 0...0xFFFF. switch (subsystemId) { case 0x13C21019: MaxSnr = 200; break; // TT-budget S2-3200 (DVB-S/DVB-S2) case 0x20130245: MaxSnr = 0x00ff; break; //PCTV Systems PCTV 73ESE } int a = int(Snr) * 100 / MaxSnr; int b = 100 - (Unc * 10 + (Ber / 256) * 5);
Sorry for not sending a proper patch as requested, I have not yet found the time to test it properly.
Best regards, Cedric
