Inovative design - that changed the world
Radio technology has developed in steps, some small and some large. Even the smallest step might have been important and be implemented in (a small scale)
radio communication equipment. Some steps are dominating - some seems smaller but were inovative and important at the time they were launched.
The purpose of this section is to give a small idea of design development steps on the way to radio technology of today.
Single Sideband - a major communication technology
A dominating step was the introduction of morse code
An inovative step was introduction of the dynamotor - providing galvanic separated high and low DC voltages for radio gear. This add comes from QST, August 1930
