> The Boehme System of transmission and reception was
> inaugurated. This system had already been in use
> in corps area nets and overseas stations as early
> as 1937. This allowed the use of perforated tapes
> for transmission of messages at rates from 75 to
> 150 words per minute.However, a radio operator
> was needed to transcribe the inked dots and dashes
> at the receiving end. Such circuits were operational
> from Washington to domestic and overseas headquarters
> stations during 1941.
> b. Radio Printer Circuits. - Since transcription
> was necessary at the receiving end, the
> system was still operating too slowly. The next step
> was the establishment of International Business
> Machine (IBM) radio printer circuits. These circuits,
> operating at 100 words a minute, offered
> printed-page reception from special typewriters,
> and eliminated manual transcription. Circuits were
> established from Washington to Algiers, Casablanca,
> Asmara, Hawaii, and Puerto Rico. This
> system had many speed-reducing characteristics resulting
> from the difference in tape width between
> the ordinary teletype and the IBM machines. Therefore,
> time was consumed in relaying from landline
> to radio network, and vice versa.
