International Radiocommunication Conference (Cairo, 1938)

1 February - 8 April 1938 - Cairo, Egypt

This was the first administrative radiocommunication conference. It was held simultaneously with the Administrative Telegraph and Telephone Conference (Cairo, 1938) under the banner the International Telecommunication Conferences.

A committee was created to resolve issues related to voting and to establish a recommendation for the next conference. A recommendation was made and a list of countries with the right to vote was created at the first joint plenary assembly of the conference. A report was compiled and was approved for future voting at conferences.

Participants agreed to use English as a supplementary language in conferences and meetings. The United States offered translating services for both of the conferences and compiled unofficial English translations. A vote determined that the Bureau would be responsible for future translations.

The increased demand and need for frequencies on intercontinental air routes was recognized. It was also decided that higher technical standards for transmitters through improved tolerance and band tables would be established. Furthermore, all old transmitters must be in compliance with the new standards by 1944.

Limits were placed on the use of spark sets and maritime use was restricted to three frequencies. In addition, modifications were made to the regulations of the Maritime Mobile Service.

The Radio Consultative Committee (CCIR) was reorganized. It would now be charged with the study of both technical and operations questions. Interval meetings would be held every three years (previously five). A class unit system created for CCIR based on the financial situation of the participating countries.

Changes were made to the Additional Radio Regulations with the establishment of a maximum charge of 20 centimes for radiotelegrams in the aeronautical service and the adoption of detailed regulations for new radio maritime letters.
