Tvheadend

I am very new to capture cards. I have a 950Q and have it attached to my antenna for ATSC broadcast signal.

I understand that the proper drivers are supposed to be installed already in the kernel.

I have tvheadend installed via apt-get.

However, in the tvheadend browser gui, under Status, it tells me my adapter has 0% signal strength. Also, the adapter only has the blue light on so I am guessing that means it is not yet receiving a signal. The adapter is listed in tvheadend as Auvitek AU8522 QAM/8VSB Frontend.

What am I missing to get this adapter running

Thanks!
