MIL-STD-187/721, MILITARY STANDARD: INTERFACE AND PERFORMANCE STANDARD FOR AUTOMATED CONTROL APPLIQUE FOR HF RADIO (18 FEB 1993) [NO S/S DOCUMENT]., The purpose of this document is to describe the technical parameters for adaptive high frequency (HF) radio thatare more advanced than those described in MIL-STD-188-141. This document is structured segmentally, with each segment having beenadded as it was developed. Together, these segments will guidethe planning of military adaptive HF radio network technologyinto the 21st century. To fully understand and utilize thisdocument, it is necessary to refer to portions of MIL-STD-188-141for the basic automatic link establishment (ALE) criteria.
