GMDSS 2187.5 kHz

Stanotte ho lasciato la radio in ascolto su 2187 kHz.
Decodifca con Multipsk.


Orari UTC, ascolti fatti con la filare da 25mt + balun 32:1, e come ricevitore il Satellit 750.
Prima di lasciare a radio incustodita e andare a letto ho verificato i livelli di segnale e rumore, direi che il QRM era pressochè zero, e il segnale ricevuto dalla Radio della Guardia Costiera Olandese (JRCC Den Helder) era attorno a 9.

Apparentemente una serata buona...Risultato stamattina: niente di nuovo a parte Kaliningrad e Novorossiysk che ricevo e decodifico per la prima volta.
