Descrizione

Ricetrasmettitore radio amatoriale per HF/50 MHz dalle molte funzioni. Potenza in uscita regolabile fino a 100 Watt su tutte le bande dai 160 metri ai 6 metri, 25 Watt nel modo AM, ed amplificatore finale realizzato con robusti MOSFET. Filtri DSP, Filtro Notch automatico, Riduzione Digitale del Rumore, Registratore Digitale, preamplificatori RF per bande basse ed alte, Dual watch. Display Omni-Glow che mostra un gran numero di parametri ed utility di aiuto nell’operare l’apparato. L’accordatore ATU interno può essere utilizzato sia in trasmissione che in ricezione. Controllo Shuttle jog e manopole indipendenti per la sintonia dei due VFO. Anno di introduzione 1997, paese di ideazione Giappone.

Tipologia : uso radioamatoriale
