STAZIONI DI TEMPO E FREQUENZA CAMPIONE

Una stazione di tempo è una stazione radio che irradia segnali di tempo; tempo che è misurato con la massima precisione   grazie a sofisticati orologi atomici e contemporaneamente è una stazione di frequenza campione, utilizza trasmettitori con altissima stabilità di modo che la sua frequenza di trasmissione è precisa.

Verificare  l’esatta calibrazione in frequenza del proprio ricevitore

Un modo semplice per il dilettante senza sofisticati strumenti da laboratorio,  scegliete una frequenza a vostro piacimento tra le stazioni  di “ Tempo e frequenza campione” in HF con il ricevitore nella posizione LSB o USB, sintonizzate la stazione sino ad azzerare esattamente il fischio del battimento con la portante,  la modulazione dovrebbe venir fuori chiara, controllate la lettura della frequenza sul display.

Le stazioni di tempo e frequenza campione  trasmettono dalle VLF/LF  alle onde corte.

In LF  si possono ascoltare  alcune stazioni europee :
