Radio broadcast .. (1922-30)

220 RADIO BROADCAST ADVERTISER Bridge great distances The new PRIESS "9" NINE brings in remote stations with astounding quality — even when the locals are at the height of their broadcasting Deep, sonorous bass notes as well as the faintest sounds of a violin—there are no "squeaks" or "howls"—no background noises. Instead a tone quality to marvel at. Because of its matchless selectivity the Priess Nine is ideally suited for use in cities and other congested broadcasting districts—it goes through the locals as though they were not there. Fourteen years of RADIO experience are back of every Priess set. A home demonstration involves no obligation and is a guarantee of your satis- faction. Write for names of dealers.
