The  lowest amateur VHF band                                   La banda piu' bassa delle VHF

shares many of the characteristics                 presenta molte caratteristiche

of both lower and higher frequencies.           comuni alle gamme piu' basse e

 Nearly every form of propagation is               piu' alte .Diverse possibilita' di

probably the most common  and                    6m come l'E sporadico durante i

popular form of propagation, single                mesi estivi e invernali, salti singoli
