ARLA/CLUSTER: Os radioamadores devem acompanhar os tempos modernos como o sempre fizeram no passado. As comunicações digitais podem ser a resposta

[João Costa > CT1FBF]

Radio amateurs should keep up with modern times

Radio amateurs made their mark in history when they discovered worldwide HF
communications while using radiotelegraphy, which is the correct term for
CW.

Ten years later they discovered VHF propagation beyond the line-of-sight to
the surprise of the radio experts.

Our early radio amateurs were true experimenters, researchers and pioneers
and they advanced amateur radio technology in their time. Today many of our
modern breed of radio amateurs are no longer interested in experimenting
but only having fun with a radio hobby.

Many shortwave broadcasting stations have closed and commercial stations
relocated to the satellite frequencies on SHF where DSTV is well
established. This includes the maritime mobile service that used many HF
bands and radiotelegraphy on their sea lanes, until they also moved to
satellite and now communicates via voice and digital. It is the VHF, UHF
and SHF spectrum that is now in great demand by the commercial radio world.

All the above does not mean that radio amateurs should abandon HF or CW,
but they should rather try and keep up with radio developments and increase
their knowledge of the VHF spectrum and the frequencies above, where the
future of radio lies including the digital communications.

The IARU is already concerned about the lack of interest in amateur radio
by the younger generations and if it stops growing then its survival is
doubtful. The younger generations are very computer literate and their
interests are a lot different than the old-timers of yesteryear and the RAE
should reflect it.

Amateur radio service needs a Renaissance, the first step is to break away
from this hobby attitude and to realize that it is an amateur radio science
with which to experiment, research and pioneer. Secondly, the amateur radio
service should broaden its field and include radio astronomy for future
space communications, which currently can cover a communication distance of
more than 21 billion kilometres from Earth.

A wider radio field enhanced by the latest radio technology will be more
exciting, attractive and have a far greater appeal to the new generations
with their open and inquiring minds. They will become fully exposed to the
new era of space travel within the next decade and this could extend the
lifespan of amateur radio service for another 100 years.
