ICOM IC-781
MITICO ed INTRAMONTABILE TX 0-30 Mhz con AT Tuner – 220v
potenza esuberante, 150w, modulatore ancora da paura, speech processor potentissimo
Apparato che costava la bellezza di 12 milioni delle vecchie lire!!
Elettronicamente perfetto, esteticamente presenta qualche ovvio segno del tempo sui case, e manca un gancio dei 2 sullo sportellino superiore, e qualche tasto non molto leggibile.
Manca imballo originale, ma in caso di spedizione, ne verra’ realizzato uno personalizzato e super protetto, ed assolutamente idoneo al trasporto
