L'Editoriale di Febbraio 2021

Lesa maestà, ma per favore!Gabriele Villa, I2VGW Non voglio fare l’avvocato di alcuno. Abbiamo già il Presidente dell’ARI che svolge in modo pregevole questa professione. Faccio il giornalista e da quarant’anni a questa parte, anche davanti alle accuse più false e idiote, ho sorvolato replicando solo alle diffamazioni. Tuttavia, e questa scelta sorprenderà probabilmente molti di voi, ho deciso di pubblicare l'e-mail che segue del socio IZ1ANK assieme a queste mie poche righe e di nobilitarla inserendola nell’editoriale di RR. Perché? Ma perché questa storia dei diplomi e dei diplomini, scritta con la solita ironia da Paolo Zaffi (che a difendersi, nel caso, è capace anche da solo) mi ha veramente annoiato. Ho letto anche se distrattamente (perché appunto mi annoiavano) commenti perfidi e velenosi di “colleghi” radioamatori che, quasi fosse un delitto di lesa maestà, si sono sentiti in dovere di insultare persino l’ARI per quell’articolo.

La sonda americana Providence, sbarcata giovedì 18 febbraio 2021 su Marte alla ricerca di antiche forme di vita, ha portato sul pianeta rosso anche il nome di Guglielmo Marconi, in una parte della memoria del computer del rover Perseverance associato allo Science Park Guglielmo Marconi di Santa Marinella. Un messaggio di Elettra Marconi. Esperimenti dell'inventore verso Marte? Come ha detto alla Radio Vaticana il professor Livio Spinelli, delegato per il Comune di Santa Marinella al Museo Marconi della cittadina tirrenica,lo studio delle microonde, avviato ad Marconi nell'ultimo scorcio della sua vita, si è rivelato decisivo anche per le esplorazioni spaziali ma - e questa è un po' una novità - Marconi “fece a suo tempo degli esperimenti radio dalla Torre Eiffel su Marte per trasmettere e ricevere le onde e addirittura speravano di avere un collegamento con qualcuno che potesse rispondere ai segnali inviati dalla Terra”. L'affascinante teoria è suffragata… [...]
