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 0x 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 = 0x; // 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...0x.
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
