19. Classification of radio frequencies

20. Frequency tolerances.

Of these questions, numbers 3, 4, 10, and 11 deal specifically with problems of broadcasting; numbers 6, 8, and 18 concern the users of radio in marine navigation; numbers 5, 15, and 16 have to do with the interference to radio reception from electrical sources. The other questions are of general interest to all radio services.

As the result of discussion of the foregoing agenda, the Bucharest meeting adopted 21 recommendations or opinions, as follows, the numbering being consecutive with opinions resulting from the previous meetings:

78. Classification of all opinions of the C. C. I. R.

79. Method of measuring harmonics (above 3,000 kilocycles) 80. Limitation of power of harmonics (above 3,000 kilocycles) 81. Synchronization of broadcast-station frequencies
