Wait, your grandma is from El Paso and she called it soup? That's wild to me because I'd figure anyone from out that way would be picky about chili in a good way. El Paso folks know their stuff when it comes to this kind of food. What brand were you using before, because now I'm wondering if my canned tomatoes are slacking too.

How many of those hundreds of reviews were from people who actually eat there regular versus folks who just wanted to yell online? The regulars showing up makes sense, they got skin in the game. Curious if the review bomb was ever as big as it looked or if half those accounts were brand new.

Sounds like your old radio had a good analog tuner which locks onto a weak signal, while the digital one jumps around trying to find the exact frequency. But the truck thing points to something else too, cheap AM radios had decent shielding and the new one might be picking up interference through the power or the case. Try running it on batteries only and see if the trucks still kill it.
