![]() Uzytkownik "Richard Fry" napisal w wiadomosci ... I am trying to find if that SSB from 1915 were the distance dependent. S* Distance from where? You are not making sense. From the station. S* ________________ 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? S* |
