24 June 2019 is the new deadline for submissions to the special issue of the ITU Journal on radiowave propagation.
radio-frequency has become essential to business and daily life, and critical to safety on land, at sea and in the sky. But it's a shared and finite global resource.
The amateur service is one of the oldest radio services, predating regulation. Recalling his earliest experiments, Marconi proudly referred to himself as an amateur. Today more than three million radio amateurs throughout the world follow in his footsteps and those of other radio pioneers, motivated by curiosity, and the desire to understand and harness the natural phenomena that influence radiowave propagation.
