WinTV-HVR-950Q

I'm using this usb tuner for OTA in the US, but have been unable to get local cable channels tuned in with TVheadend. Does anyone have any experience with this tuner or tuning cable channels in general. I trying to move away from my old setup(an old pc tower with a WinTv HVR-1600 running Windows 7 WMC and Plex Media Server to serve my smart TV's) to a smaller quieter setup like an ODROID or Raspberry Pi. But I'd really like to be able to record my analog cable channels which I am able to do with the 1600. Any help would be greatly appreciated, I have tried number of different solutions so far and really like LibreELEC. Thanks.
