Quando alla fine degli anni 60 la gamma dei due metri cessava di essere "sperimentale" e diventava ufficialmente gamma amatoriale cominciava l'industrializzazione di apparati portatili sulla nuova frequenza. Uno dei primi prototti è stato appunto lo Standard SR-C146 anche commercializzato con il marchio Marantz e nome del modello C145BN.
Venne definito, giustamente per quell'epoca, il "piu piccolo del mondo".
