There were no broadcasting stations of any kind in 1915.

The first station that could even remotely be called a broadcasting station
was in 1916 and it broadcasted weather reports in morse code.

The first experimental AM broadcast stations started in 1919 and regular AM
broadcasting started in 1920 when all the spark gap morse transmitters
were shut down.


Make that 1906 for the first experimental AM broadcast.

Again you must differentiate between sporadic demonstrations and the
setting up of a station with scheduled programming, which is what the
discussion is about.
