If what you say is true about UHF, why are radios being advertised as usable from 400-520 MHz?

Just because a radio will receive something under some conditions, does not mean that it is "usable".

I can listen to WWV in FM mode and hear the broadcast perfectly fine.

I can listen to the various NOAA FM weather stations in AM mode and hear the broadcast perfectly fine.

In Los Angeles I could listen to the (very near) local AM broadcast station on any frequency on some radios (including FM broadcast-only receivers).
