FACTS ON FACSIMILE
Radio's method of printing a newspaper in the home comes of age
Twenty-three radio stations are licensed to send out facsimile signals, and two manufacturers are now turning out receivers. Thus, another offshoot of radio shows definite signs of coming of age.
Two systems are now being used— that developed by W. G. Finch, and the system worked out by ECA engineers.
In the ECA facsimile, printing is accomplished by a narrow bar which pinches carbon and white paper against a single spiral turn of raised wire on a rotating drum. As the drum rotates, the point of intersection between the printer bar and the raised wire travels across the page in synchronism with the scanning light spot at the sending station, and, by means of dots and lines, reconstructs a facsimile of the original graphic material.
Electro-chemical recording
In the Finch reception, a stylus moves back and forth across the paper emitting small electrical impulses synchronized with each dot as scanned and transmitted by the broadcasting station. Each dot penetrates the chemically-treated white coating on the paper, removing the white and allowing the black paper to show through in black dots. A specially prepared paper is necessary in the Finch system.
Using the Finch system, the Crosley Corp. is selling "for demonstration and experimental purposes" a facsimile receiver known under the patented name of "Eeado". Complete with electric switching clock, printer and receiver, it costs $150. If one now has a radio delivering an output of 5 watts or better, the printer may be connected to it, saving some $60. To stimulate interest, Crosley is also selling its dealers a record player at $36. Used in conjunction with the Eeado, this player gives off sound impulses, which are translated into facsimile reproduction by the Eeado.
In 16 cities
ECA has not announced its sets for general distribution, but is using them in areas where facsimile transmitting licenses have been granted. On granting such a license, the FCC demands that 50 facsimile receivers be purchased by the station and distributed for experimental reporting. So far, twenty-three stations have received these experimental licenses — fourteen on the broadcast band and nine on the ultra-short waves. The latter permits broadcasting of facsimile at any time ; but on the broadcast band, transmission is limited to the hours between midnight and 6 a.m.
A list of the facsimile stations is also on this page, and shows that al

Newspapers interested
In most cases, newspaper-owned stations have taken up facsimile. While not expected to displace newspaper, it is thought that facsimile will supplement it. Thus, papers are vitally interested.
Eadio folk believe there will be a comfortable market in facsimile during 1939. Principal obstacles to be hurdled are: speeding up reception (now three feet per hour) and lowering the price. As the demand increases, it is expectd that a speeding up of production will help cut the price.
PRESS AGENT'S PAL
The much-maligned press agent has a new helper, facsimile. Comes WOE of the Mutual network with news that its daily handouts are being "peep swished" over 710 kilocycles at the close of the station's regular programs.
Under a specially designed masthead, "WOE EADIO PEINT," executed by WOE's chief engineer, J. E. Poppele, the facsimile-casts also include photos of the station's activities.
