The term "local stations" as used above has also been used recently in
several other threads. I am curious what the readers of this forum would
consider to be a "local station"?

I have no idea what they use to describe them now... but I remember that
AM's used to be basically classed as either Local (frequencies such as
1230.. 1 KW or less daytime power), Regional (frequencies such as 620... 5
KW-50KW daytime power) and Clear channel (frequencies such as 1160.. 50 KW
daytime and nighttime power). Locals were generally required to go off the
air at dusk unless they had specific nighttime authorization, which
generally required drastic power reduction and/or directional antenna system
(most with nighttime authorization would run at 250 watts, but I know of
some that run as little as 10 watts nighttime... as in why bother??)

Well yes, a "Local" station is an obsolete FCC term for what are now
called class C stations. Class C stations operate with full power both day
and night by the way. That isn't exactly what I was asking about though,
considering the FCC doesn't have dominion over Australia, which is where
the post originated that used the term.

I was using the term in the context of a receiver designed to receive only
"local stations", and not intended for receiving distant stations, as for
example the old AA4 radios that didn't have an IF amplifier stage, where
the converter drove the detector directly.

What I was wondering was what range of field strengths those "local
station" receivers might have been intended to receive?
