Welcome, comfortably_numb:
You should be receiving KMJC if it is on the air. Anyone else in your area having trouble receiving it?
What antenna and preamp are you using?
If it IS on the air, you must be having equipment trouble or something on N Holmes Rd is blocking the signal.
I don't know your exact address, but this is what I see:
You can do your own green lines here by moving the cursor (drag and drop) to the antenna location.

Have you tried another TV, another antenna, or another antenna location?
The only other thing I can think of is that the tvfool report is wrong and KMJC has a very directional transmitting antenna that sends very little signal in your direction.
