TELEVISION AND RADIOMOVIES 345
comparing reports from amateurs with the order of picture sequence in the broadcast on that particular evening.
All the broadcasts have been in photographic silhouette, or in black and white cartoon drawings. But those cartoonists we have patronized don't seem to be able to grasp the requirements of radiomovies, and so, after spending considerable money with them, we abandoned the cartoonist as an undependable source of picture story for us.
I had, however, designed a silhouette studio equipment which was already working excellently, and with which we can produce radiomovie stories in silhouette as fast and as satisfactorily as is usual with regular movie negative in regular movie studios, and at small cost.
When I first designed this equipment and worked out the operation methods, I really did not think of it as new ; but it seems on search of available motion picture references that this is a new attainment.
We also discovered scenario writer talent in our laboratory staff, and so we are a self-sufficient institution, from story concept to the reproduction of this movie story in your house, delivered there over radio channels.
All of these broadcasts were on ten kilocycle channels. Some months ago the Federal Radio Commission, on the showing of what we had already accomplished, and the explanation that radio transmission of the halftones of television and regular theater movie film required a broader channel than the ten kilocycle width employed in audible radio, set aside eight channels, each one hundred kilocycles wide for visual radio.
We then immediately proceeded with the erection and equipment of a powerful station in the country about five miles north of Washington. The broadcast frequencies were 2850 to 2950 kilocycles and 2000 to 2100 kilocycles, for distant and for local reception, respectively. This station's broadcasts are well received by those who have rebuilt their radio receivers for the new frequencies, but I am doubtful that we shall build up as large an audience on these frequencies as quickly as we did on the old frequencies.
Of the little kit set receivers we sold many thousands at $2.50 each. They cost $3.10, but I made money because I sold so many of them.
That is literally true, for we built up a demand for a better receiver, and a public confidence that television and radiomovies was a practical thing, possible of wide usefulness as development progresses.
To date, the quartz or glass rod drum scanner continues to represent the best type of receiver. It makes a larger and brighter picture with
