Report on FM C. M. Jansky Jr., chairman of Panel 5 on FM Broadcasting, said !;hat after considerable study of (inodulation types it was concluded |;hat "there are no systems of nodulation, classified or otherwise, :tvhich show any indication of being 4ither as good or better than the ifrequency modulation type now in ijse." ; As to position in the spectrum, Panel 4 concluded that the present band, in the vicinity of 50 mc, bhould be maintained. It was further agreed, he said, that the pres[;^nt channel width of 200 kc be ^maintained. Controversy with Panel ji> (television) over the number of 'phannels required for FM was ii-roned out, he reported, at confer:|2nces with Panels 6 and 2 (fre/quency allocation) and it was ?iagreed that Panel 5 would make ^jthe recommendation that FM ' broadcasting be assigned 75 channels of 200 kc each between 41 liand 56 mc. "It is realized of course , that this assignment of 75 channels lis slightly less than the number rllspecified in the original Panel 5 .report," said Dr. Jansky. "Never,,,theless it is not the desire of Panel to in any way stand in the way ;-of a considered, overall proposal ttfully recognizing the great demand j'for radio facilities for services I'Other than the one with which ithe panel on FM broadcasting is ^concerned." The original Panel 5 irequest was for 80-100 channels for "commercial and non-commercial jstations, starting in the vicinity of |40 mc and comprising a band of 16-20 mc. !

Concluding his statement Dr. Jansky said : "The potentiality for public service in FM broadcasting far transcends those of the older AM system. If the standards finally adopted are right, then the greatest possible benefit to the public will accrue. If they are wrong, then to the extent they are wrong will horizons be limited and the future of the art impaired. Knowing what is done cannot always be undone has led us to concentrate our thought to date almost entiiely upon the fundamental, basic allocation standards which must furnish the foundations upon which the complete structure will be built rather than to devote much time to details. "When you have decided first tlie position for FM broadcasting in the radio spectrum, second the width of channel to be used and third the number of channels, that is, the width of band to be assigned this new and vastly improved service, then industry can proceed with plans for the building of radio receivers and transmitters, and io establish stations." Television Space Recommendations that the Commission assign a sufficient number of 6 mc channels in the region of the present A and B television channels (50-294 mc) to provide competitive nationwide service, and authorize commercial relay stations and "assign a sufficient number of channels commensurate with the needs of the commercial television broadcasting stations" in the 300 WITH A WOMAN'S PROGRAM THAT HAS GENERAL APPEAL...
