Broadcasting Telecasting (Oct-Dec 1955)

Attention, 'Broadcatt Mm/ 35 HistoryMaking Articles on "Scatter Propagation" 'henever radio seemingly reaches its limit, such as the "line of sight" range of TV, then radio engineers find a way to smash that limit . . . and open up whole new fields. Now it's "Scatter Propagation". . . the way to unlimit "line of sight" broadcasting ... discovered and perfected by radio engineers. And now, for the first time, it is fully reported in 35 great articles in the October issue of "Proceedings of the IRE." All IRE members will devour this issue and treasure it as they have the history-making issues on Color TV, Transistors, Electric Computers, etc. This October number will rank high as a practical service to the whole industry— a great reference text of 380 pages— and someday become a collector's item among radio engineers.
