If so, for test purposes remove anything that can degrade or improve RF. It looks like the tuner gets into lock briefly but falls out, implying abnormal RF conditions. When it locks you have perfect SNR, kind of implying that the signal may be too strong. Additionally, for all your testing, repeat the tests on tuner#2 by azap -a1 -r c112. Additionally, try channel 83 or edit the conf file and add some lower channels in the 40-80 range where the RF characteristics would be wildly different. I'd like to see how the card performs in these circumstances for you.
