Howdy! Tony,
Many Years ago I remember reading about Youngsters who lived in the outback got their School Lessons using a Two Way Radio.
I wanted to ask You what Frequency was used back then for Teachers to
talk with their Students.
That would be the Royal Flying Doctor Service frequencies. Exact frequency would depend on what base station and the distances to be covered. To this day, the RFDS have a range of frequencies spread throughout HF.
I first thought it might be the 27 Mc/s Band that was used by Hams
until September 1958 when the Citizens Radio Service began here in the USA.
Nope, totally wrong propagation characteristics - unreliable skip and skip distance usually too great for the range required, unless using Sporadic E.
... Imagine the music as a set of disconnected events
