Description
From a scrapbook compiled by Dean A. Lewis. According to a typed note on The American Radio Relay League Member's Correspondence accompanying the photo: "Special License Station 1ZL / 30 Williams Street, Northampton, Mass. / 1913-1917 This picture was taken in 1915 or 1916 by Glenn Sabin, (now W1ZS). Glenn was our associate at 1ZL and his knowledge of radio, telegraphy and communications at that time was greatly responsible for the format of the station. The switchboard with its meters and open switches added a touch of commercial design. The receiver was of our own ideas, icorporating remote control for the slide tuner and other personal ideas. Perhaps of interest the rheostat for the filament supply to the audions was somewhat of an innovation. The upper right hand switch incorporated step resistances between contacts. The switch below divided the resistance step above into about twenty steps. A decade type rheostat!!! On following pages the pictures of the receiver and other parts of the rig will show details. The transmitter was underneath the table to the right. Our present QSL card on later pages shows specifications as to power and equipment. The push button switch at the left of the two keys controlled the quenched spark gap motor and transmitter power increase and decrease in steps. Later pages will also show the station house, antenna and special power supply put in by the local power company. (We blinked all the neighborhood lights at first.) But no TVI!!!! (The number SRM9047 at the right side of the picture is an index assigned by George Clark of RCA for an exhibit of old time equipment.)
