NAVTEX Logs 518 khz del 19-20-21 Novembre.

Dopo qualche giorno di assenza forzata dal QTH, ma con il sistema Elad FDM-S1 ovviamente al lavoro sui 518 khz, pubblico oggi 3 logs consecutivi, che mostrano in questi tre giorni un picco della propagazione nella notte tra il 19 e il 20 novembre.

La decodifica è eccezionalmente perfetta, mentre la stessa stazione era completamente assente la notte precedente e lo è stata anche la successiva. Pubblicherò in seguito una analisi meteo e delle condizioni solari per capire l'interazione di questi fenomeni sulla ricezione.

L'immagine sottostante riporta la situazione meteo attuale all'infrarosso:

Situazione non ottimale, con rumore di fondo generato dai temporali molto alto in questo momento, intorno ai -100dBm.

In ogni caso, e come al solito, buoni ascolti a tutti.
