On y lit quelques déclarations intéressantes :
"Amateurs have established two-way communication repeatedly over paths of more than 300 km at 47 GHz and of more than 200 km at higher frequencies. If a future World Radiocomunication Conference (WRC) extends allocations above 275 GHz, adequate provisions for amateur experimentation should be made."
"In addition to extending the frontiers of frequency and wavelength, amateurs are refining communication protocols by optimizing coding, modulation, and digital signal processing to improve weak-signal performance."
"Amateur licensees are grateful that the ITU Member States continue to recognize the bene-fits of providing direct access to the radio spec-trum to qualified individuals. Access to frequency bands spaced throughout the radio spectrum is essential to the continued success of the amateur service."
