Phil lives line of sight from the Australian Broadcasting Transmitter
installation in the northern suburbs of Perth. There are three AM transmitters
there which run 24 hours a day, seven days a week:
6PB at 10 kW on 585 kHz; 6RN at 20 kW on 810 kHz; and 6WF at 50 kW on 720 kHz,
That's typical of medium-size cities in the US for high power
broadcasters, but major cities typically have twice as many. Both large
and medium-size cities, as well as smaller ones, typically have 6-10
stations in the 5kW range, and more in the 1kW range. Chicago is typical
of a large city (like New York, Boston, Los Angeles, San Francisco) --
it has 50kW on 670 kHz, 720 kHz, 780 kHz, 890 kHz, and 1,000 kHz.
There's also a daytime only station with 50kW on 1160 kHz. Cincinnati is
typical of smaller cities like Indianapolis, Detroit, Minneapolis,
Cleveland, St Louis, and New Orleans, with 2-3 50kW stations and many
smaller ones. Cincinnati 50kW stations are on 700 kHz and 1530 kHz.
I grew up in a small town in WV, with three 5 kW stations within two
miles on 800 kHz, 930 kHz, and 1470 kHz.
Bottom line -- there's a lot more broadcasting in the US than in most
countries.
