[QUOTE="dmaavrigdo, post: 1086984, member: 323068"] After research I see that the Si 2166 is not the tuner but a "DVB-S/S2/S2X Digital TV Demodulator" and it gets its inputs from a tuner/tuners . "A zero-IF interface (differential) allows for a seamless connection to market proven satellite silicon tuners" I'm not ready yet to lever the cover off the tuner module so don't know which one it is. I have looked at the data sheet of one such tuner the MAX2112 and see that it's gain can be controlled by the SPI interface or the voltage on a pin. So a brave experimenter could possibly add a potentiometer! Perhaps there is a file to modify. Haven't found it yet. [/QUOTE]
