E' vero però che l'evoluzione tecnica (e non mi riferisco ai ponti o
alle comunicazioni digitali citate da Fausto, piuttosto agli apparati
stessi) è tale da richiedere competenze teoriche e pratiche più
approfondite. Anche negli anni '60 c'è chi, con il passaggio dall'AM
alla SSB, con apparati concettualmente più complessi, ha passato il
testimone.
Anni fa avevo trovato questa tesi di laurea, di un OM canadese, che
analizza varie tappe cronologiche nell'evoluzione dell'hamradio. Forse
significativo è la fase 1975-2000:

Amateur Radio 1975 - 2000
The popularization of digital electronics and, most
significantly, the introduction of the personal computer to the hobby
in the mid-1970s initiated a profound change in the nature and use of
amateur radio. The increased functionality and performance in radio
equipment made possible by advances in electronics placed
greater burden on those amateur hobbyists wishing to understand the
technology. For the first time in amateur radio’s history, the
complexity of the equipment eclipsed the average hobbyist’s
ability to understand how it worked. Nor could malfunctioning
equipment be repaired - the high complexity of the new solid state gear
precluded repair by the amateur himself.
Self-reliance had previously been the hallmark of amateur radio.
Amateurs were proud of their ability to build, repair, and modify their
own equipment - in many cases, this tinkering resulted in creative new
circuits and modes of operation. The period leading up to the new
century saw amateurs lose this capability to tinker with their equipment
at all but the most basic level. The introduction of the
microprocessor into everyday amateur operation was a pivotal
moment for amateur radio. At this moment the hobby broke with the past
and entered an arguably much more complex phase. Digital replaced
analog, old skill sets became largely redundant, and the computer oddly
constrained the future of the hobby while simultaneously enabling
incredible new modes, techniques, and social applications of amateur
radio. The new skills introduced to the hobby through the personal
computer challenged the traditional amateur skill set. Software
became the new region in which development and tinkering served
to increase amateur communication capabilities
