You see, though, it's not dBm for AM radio....it's V/m, since there's no "typical"
impedance associated with the receiving antenna.

And in the end it's still a question of receiver design, anyway. And, worth noting,
is that different antenna designs will have different close-range propagation
characteristics, so that it can't be specifically stated without knowing the antenna.
This is, after all, why the FCC specifies inverse km measurements, and those
measurements are done in far-field conditions.

base
of the tower..

I think his question is how many dBm would be received at the front end
when sitting at the base of the tower. Not how many dBm can be received
and still use the radio.
