You are very welcome, thank you.

We generally recommend Linux users purchase cards that are already
supported (or semi supported), such as the HVR2250. If you're keen
enough to tackle adding support for a new board then that's great
news, but very few people usually have experience with hardware not
yet supported.

The channels.conf is capable of support digital cable and ATSC, simply
change the modulation scheme and your target frequency and try again.

A quick google for an equivalent ATSC channels.conf provides a lot of
useful information.

Create your channels.conf to match your target frequencies in Hz and
use azap to debug.

Eg.

KPAX-CW:177028615:8VSB:65:68:2
