Re: Kworld ATSC usb 435Q device and RF tracking filter calibration

I have this stick running on my Mythtv box with the patch and a quick
hack to disable the additional calibrations. It works, most of the
time, but will occasionally stop working until I reboot. The frequency
of this is reduced if I tell Mythbackend to only grab the tuner when
it needs it... might be a calibration issue, might be marginal
hardware overheating.

I took a patch put forth a while back on this list and was able to put that on the kernel 2.6.31.6. I am able to tune and lock channels with it, but, like the people earlier, I see the RF tracking filter calibration in the syslogs and tuning takes some time.
