Overseas Representative: Ad Auriema, Inc., 89 Broad St., New York 4, N.Y. at the end of '52, 1000 broadcast applications were still pending, and some of the station requests were becoming really ancient items. In 1944, KARM of Fresno, California, asked permission to change its frequency from 1430 to 1030 kc. Because of the still -pending decision on the seven - year clear -channel and daytime sky - wave case, this request and 77 others, too, are still waiting for action. WOWO, in Ft. Wayne, who asked for permission to use 50 kilowatts with a directional antenna about six years ago, is also waiting for a decision, delayed because of an anti -trust investigation of the station's licensee, and a review of the proposed antenna tower and its possible air hazard height and location. WITH OVER 200 new TV authorizations now on the books, and a surge of grants on the way, it appears as if the early summer may see as many as 500 approvals recorded. During the first few weeks of the new year, the active hearing group sent out OK's for nearly 100 stations, and this record will be broken soon. As this column is being written, all but two states (New Hampshire and Vermont) have TV and they'll probably have video -facility grants soon, too. The continued broad distribution of new TVers is strikingly illustrated in the listing appearing on page 74 of this issue. It will be noted that many western states without any TV are now among those in the approved column; Montana, to illustrate, has received three standard -band grants for Channels 4, 5, and 8. New Mexico will have a Channel 2 station, and Wyoming is now scheduled to be the home of a Channel 5 transmitter. An ultra -high station (26) has been alloted to Chicago, and in Fargo, North Dakota, a Channel 6 station will be placed on the air soon. A BUDGET OF OVER $8- MILLION, to run the Commission during the fiscal year of '54, was submitted by former President Truman just before he left office. More than $1.5- million of the funds were said to be for radio - monitoring and direction- finding. For the broadcast division, $1,667,074 is being sought; for applied technical research and frequency allocation activities, nearly $500,000; for safety and special radio services, over $700,- 000; and for executive staff operation, over $1- million and a half. A boost of nearly $500.000 appears in the broadcast request to take care of the additional examiner teams that will be required to process the new station applications; such a team consists of an attorney, engineer, accountant, clerical help, and the examiner. Currently there are 10 examiner teams; the additional funds should make it possible to hire another 10 teams. TV was described as a key medium, (Continued on page 138) RADIO & TELEVISION NEWS
