We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

These separations are calculated to minimize objectionable interference in the good service areas of stations about 90 per cent of the time approximately as follows:
(1) 50 to 250 Local Channel, 2 millivolts, 7 to 15 miles
(2) 250 T. to 2.5 10,^ Regional Channel, 1 millivolt, 26 to 55 miles
(3) 5 10'" to 10 10"', High Power Regional Channel, 1 millivolt, 65 to 80 miles
(4) 5 10" to 50 10", Clear Channel, 0.5 millivolt, 93 to 160 miles.
irfi'' STATION DENIED
j-he application of John H. Dolan, Boston, Mass, requesting authority to erect a new station on 1370 kc to operate unlimited time was denied by the Commission, sus¬ taining the examiner (Report 215) and holding the applicant had failed to show satis¬ factory financial responsibility.
The Commission also granted the television application of the Chicago Federa¬ tion of Labor, upholding the report of Ex^aminer Pratt (Report 225). The station v'ould operate on the band 2750 to 2850 kc with power of 500 "A and unlimited time.
