You are correct, WZAW doesn't show on the tvfool report, but it does show on a rabbitears.info search. The tvfool website is short on people to do updates.

What you get is a lot like a tvfool report with the channels listed in decreasing order of strength.
WZAW is about 15 dB weaker, so you need an antenna with more gain aimed directly at it.
