WWL is protected as a class A station. The spacing requirements for class A AM signals are huge.
I don't see why WWL would file an objection - all they should care about is advertising revenue from New Orleans. Listening outside of New Orleans, particularly in Houston, is unimportant. Or - so I have been told ------
You'd think WWL wouldn't care. I was working for one station where there must have been a skip or incredible skywave near sunset to pull in our daytime station 250 miles away and in the opposite direction of our directional antennas. The 50 kw. 200 miles further away wanted to know why their listener 200 miles from their city was receiving the station I was working for. As one broadcaster put it, (a station) 'taking only one listener is too many', implying that would be the radio version of starting a war. Even so, WWL is protected by FCC Rules on separation and that is the reason for the rejection, it would seem.
Such stations served an important service early in radio's history. With few rural stations, the stations were a way to inform people over a wide area. For example, during World War II, these stations allowed the whole nation to stay informed on the war even if that person was so far in the sticks the sticks were out in the sticks.
If only 10% of our population is not in urban areas, that is still 30 million people - relying on DX / skywave for their radio service.
Stop in one of those towns and you will get a real taste of rural America and what they think of radio stations not caring about their DX listeners.
I remember a rest stop on I-20 - Colorado City about 40 years ago. Playing on their AM radio - WBAP. About 250 miles away. That was their "local" station. These days - looks like they got one of their own - finally.
It's kind of like that nearly everywhere in the USA.
Mitchell County has both an AM and FM, and there are now quite a few other FMs penetrating the county.
and with a little persuasion convinced the neighbors to let me repair theirs - so I have perfect AM reception again.
Maybe you're closer to your neighbors than I am, but if my neighbor tried to do what you did, I would give him a funny look and shut the door in his face.
What you did is almost OCD. But more power to you for doing it, I guess.
