L'Editoriale di ottobre 2024

/Spe • ri • men • tà • re/Alessio Sacchi, IZ4EFN Quando, nel 2023, iniziammo un percorso di collaborazione con il MIMIT a tema sperimentazioni frequenziali ottenendo un primo GO per la gamma 70 MHz, ci sembrò utile e formativo creare un portale per monitorare l’andamento degli esperimenti su questa nuova banda, creando uno strumento inedito: il portale 70mhz.ari.it. A un anno di distanza, i radioamatori italiani possono continuare a sperimentare in 70 MHz, ma anche in 40 MHz e finalmente iniziare ad abbattere il muro dei 1830 kHz, decisamente rilevante per chi opera in 160 metri soprattutto verso altre regioni ITU e durante i contest. Da qui l’idea di spostarci su sperimentazioni.ari.it, con l’intento di creare un contenitore che raccolga le nostre esperienze e ci spinga a continuare l’attività in sinergia con il MIMIT, auspicabilmente anno dopo anno.

This sounds rather technical, but aircraft scatter is actually very easy; here in north-west Europe there are so many planes in the sky that aircraft […] [...]
