Web SDR

Cos’è un WebSDR,

Prima dobbiamo capire cos’è SDR “Software Defined Radio” essa è una tecnologia che permette di costruire apparati radio non più strettamente realizzati come puro hardware ovvero con circuiti e dispositivi elettronici, ma basati, ovvero “definiti” in software in funzione su un PC o un sistema embedded. quindi questo particolare ricevitore SDR “Software Defined Radio” quando viene connesso a Internet dà la facoltà a molti OM e SWL di ascoltare segnali diversi e sintonizzarsi in modo indipendente, rivoluzionando l’ascolto dei classici ricevitori esistenti.

Di seguito un elenco di alcuni server WebSDR attivi molto interessanti e curiosi:
