,,.;i . ED^'vAElD L. NELSON of Bell Laboratories stated that the proposed order was fundamentally sound and doesTiut 'lnvdlVB 'precis ion unknown to the industry generally. Intrachannel beatnote will be rare, probably about 10 or 20 cycles, with 50 cycle deviation, he said. A great improvement in service would result with. . 50 , cycle deviation whereas if 100 or 250-;.cycle deviation were permitted the'-piiblfc" 'woul'd doubtless be unable to notice any i'mprbvement in present service. ^e investment required would be comparatively srna.ll when measured against . the. amprovement un service which would result. Mr. Nel¬ son declared that there was no major’ obstacle in the way of accomplishing the result intended by the proposed ‘order although he admitted that many stations would be required to make changes in equipm.ent. Mr. Nelson cited ''numerous measurements rpade-Kby-3elL Laboratories over a period of two years to support his statements." Competent operators must be charge of st.ation eauipment if frequency stability Is' to be maintained , he said, noting that General Order 106 will require freque*ht checks .and aid materially in frequency maintenance.. ..Qp.e.stione.d,.cl9s.ely^. Mh-^'Nelson 'declared that the proposed order would not work 'undhe hardship -upon local or. regional stations and that the outlay would be more than justified with the resulting improvement in service. G. A. YOUNG .pf. Wpstefn.. Electric. Company stated that hi's company has manu¬ factured equipmerit whiCh" will enabTel stations to comply with the proposed order. Much of Mr Young^s testimony dealt with cost data. J, COIjEHANv.of ECA-Ylct op Company st-ted that within the good service of a s-tation 'there woixld be' a defihTte 'improvement in reception although in what is known as the "m.ush area” 'the "flutter effect would be more noticeable than at present. He stated that his company was prepared to deliver equipment^ necess¬ ary to ma.intain the prapOSed' standard. altho\igh he was unable to state costs. He said the cost wopld'te. fixed' to 'meet competition in the field. Mr. Yost called for 'a representative of the EE FOREST COMPANY but there was no response. _ r <. : J, W, HORTON of General' Radio '.Conipany spoke briefly about frequency stand¬ ards and the work his company has 'been doing. He added that his company manu¬ factures monitoring equipm.ent which, he . then described. -To obtain satisfactory results, he said, the.,c,o -operation Of' .all stations will be necessary. T, A. M. CRiilTEN, cohs'urting' radio engineer, Washington, D. C. testifiei that it was his opinion that ,not only is such an order practicable but that It is also necessary in the interest of .the public as well as of nearly every re¬ gional and local, station.' It will, be one of the greatest advances since 192?' toward improving the rodio' broadcast si t-ua t ion , he said. Precise freouency control in the order of 50 'cycles will eliminate much of the heterodyne now existing between stations assigned .to the same frequency -he said, ,and this in turn will res^i.'t in. sn increase.’ of the"night service area at each of such sta¬ tions as well 'as improye gfeatiy the ch-racter of reception in the present nigh service area. It will' perm.it a little closer geographical spacing between stations assigned the same frequency especially when such stations utilize "chain” pxograms...... It will . also Ip'eir mi t of other applications such as' improved service by"'increase:d power in certain’ 'localities , or by adding stations on the same frequency where the geographical spacings will permit. Evidence is available, he said, to the effect that:
