That is just a correlation. Those that

For some reason, the build system in your tree doesn't want to build
cx88-dvb.ko Even after doing make allyesconfig , I still get:

Some tuners benefit from changing the AGC take over point from its default
value. For my HD-3000 with a Thomson DTT7612, it appears to increase SNR
by 0.19 dB. I tested it against my weakest (20.0 dB) and strongest (28.2
dB) OTA stations. Both SNR readings went up by an average 0.19 dB from
