Thanks for the report and sorry for the long delay.
The original patch was reverted, this is what confused you. When i take
this into account, your report is close to what i expected. Meanwhile
i tried to cross check with the windows driver and i came to slightly
different values. I will attach a patch that should apply smoothly
to the current repository. Can you please give this one a try and
report? It patches both, tda10086 and tda8263
I expect that the signal strength still is lower, but also the BER
which is more important.

Best regards
