MIL-STD-188-243

Abstract

The purpose of this document is to establish the minimum essential interoperability and performance requirements necessary for tactical single channel UHF radio communications equipment. This standard addresses ground-to-air, air-to-air, ship-to-shore, and ship-to-ship tactical single channel UHF radio communications equipment. The requirements established by this document may be exceeded in order to satisfy specific operational requirements or to incorporate technological improvements, provided that interoperability is maintained. <br>This standard is mandatory within the Department of Defense (DoD) in the design and development of new tactical single channel UHF radio communications equipment. Major modifications to existing tactical single channel UHF radio communications equipment shall comply with the requirements contained in this document. The term "single channel" refers to radios that are capable of transmitting, receiving, or transmitting and receiving only one discrete RF envelope at a time per transmit or receive section. This document encompasses radios that may be tuned or selected to a preset channel, but is not applicable to multichannel radios (a multichannel radio is defined as having two or more complete transmit or receive RF portions capable of operating on multiple frequencies, simultaneously). <br>The requirements contained in this document are mandatory if the word "shall" is used in conjunction with the requirement. If the word "should" or "may' is used, the requirement is optional. Non-mandatory design objectives will normally be abbreviated as (DO). The term "radio equipment" will hereafter be used to refer to tactical single channel UHF radio communications equipment subject to the requirements herein.
