Self-training, intercommunication and technical investigations: the amateur
service in the 21st Century

The secretary of the International Amateur Radio Union (IARU) *David Sumner
K1ZZ* has written a four page article about amateur radio for the ITU News
Magazine.

He notes:

"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."
