 ing procedure: 



1. Stations specifically recommended for charting will be charted regardless of other 

 radio aids in the locality. Chart elevation above Mean High Water if exceptionally 

 high. 



2. Stations shall be charted in areas not adequately covered by other radio aids if accurate 

 positions are available. 



3. Whenever the towers of commercial AM broadcasting stations are charted as land- 

 marks add their call letters and frequency. Omit call letters at TV and FM towers.

4. Obstruction lights on all towers shall be omitted vmless specifically requested. 



5. On charts of exclusively inland river areas, broadcasting stations shall not be charted 

 unless the tower is recommended as a visual landmark.
