I am trying to find if that SSB from 1915 were the distance dependent.

Distance from where? You are not making sense.

From the station.

Radio waves behaved the same in 1915 as they do now.

The distance to a given field intensity, for the same conditions, is the
same now as it was then.

Look at the damped waves: http://en.wikipedia.org/wiki/Damped_wave

The damped waves pulses are simillar to AM (amplitude of oscillation
decreases/increases with time).

The decreasing/increasing may be sharp or gently.

The old damped waves " transmissions have a wide bandwidth".

Was the bandwith the distance dependent?
