Kenwood R2000 un gradito ritorno...

Kenwood R2000, posseduto diversi anni fa, in questi giorni ho deciso di riprenderne uno e affiancarlo al fratello maggiore R5000. Un pezzo vissuto con qualche segno sul cover superiore ma ottimamente funzionante e completo di converter VHF. Grazie al suo generoso diffusore frontale, offre un ascolto corposo e molto marcato specialmente sintonizzando le stazoni broadcasting. Ora la postazione è  nuovamente satura di apparecchi riceventi... e come dice l'amico Girolla non resta altro che accenderle ed "ASCOLTARE".
