70 dBu is principal city coverage for FM, not for AM.

Where does it say +70 dBu is FM only?

3 mV/m and up is a very strong interference free signal on AM. For KNX I
get -55 dBm or +20 over S9 on the signal strength meter as a reference.
KVTA which meets your 10 mV/m criteria is almost -45 dBm and not quite
+30 over S9. My reception is no different between the two stations. You
getting the drift of this?


The evidence from hundreds of thousands of listening incidents shows that
there is essentially no listening outside the 10 mvm in the LA metro. KNX
has zero at home or at work audience in your area (your ZIP and contiguous
ones) because the signal is not good enough to please listeners.

While most receivers have some sort of AGC circuit, signals below the 10
mV/m range just don't satisfy listeners enough to get listening.

My point comes from the hard facts of actual listening. There is none.
Whether a signal is receivable or not, listeners have decided it is not
listenable and do not tune in.
