been obtained.

3. REQUIREMENTS

3.1 First article. When specified (see 6.2), the contractor shall furnish sample units for

first article inspection in accordance with 4.2.

3.2 Materials. The contractor shall select materials that are fully capable of meeting all of

the operational and environmental requirements specified herein. The materials specified in the

applicable drawings are recommended, but are not mandatory. Selection of the class, grade or

type part shall be that the material will be able to perform its intended function when it is

assembled. Verification of the supplier meeting the overall performance requirements shall be

the governing acceptance standard. Recovered materials shall be used to the maximum extent

possible.

3.3 Description. Radio Set AN/GRC-103(V)3 provides for multichannel, line-of-sight,

two-way communications in the frequency range of 695-1000 MHz (Channels 990-1600). This

version is intended primarily for use as a radio link in a communications network which may

include carrier telephone and teletypewriter sets. The radio set is used in pairs: one at each end

of the line-of-sight path. The radio set may be used with 6/12 or 24 channel Pulse Code

Modulation (PCM) equipment or with 4 channel frequency division modulation (FDM) when

associated with approximate interface equipment. As currently designed, the set provides

channel assignments on each half and full megacycle points (1/2 MHz spacing).

3.4 Design. The radio set and associated subassemblies and components shall meet the

dimensions and dimensional tolerances of the drawings list in the following Data List drawings:
