scope:

- The equipment covered by this specification shall provide radio frequency reception and transmission of amplitude modulation (AM) signals on any of 7,000 channels in 25 kilohertz (KHz) increments in the 225.000 through 399.975 megahertz (MHz) radio frequency (RF) band. The main function of the equipment is to provide simplex two way communications of:

a. Amplitude Modulation (AM) Normal Voice

b. Amplitude Modulation (AM) Secure Voice

Additionally, the equipment shall provide the capabilities for:

a. Continuous monitoring of the ultrahigh frequency (UHF) AM emergency channel by incorporation of a separate fixed tuned guard receiver.

b. Reception of UHF automatic direction finder (ADF) signals on any selected channel.

c. Transmission of signals from a reference signal generator of the Command Active Sonobuoy System (CASS) or Directional Command Active Sonobuoy System (DICASS) on a preselected channel - AN/ARC-159(v)Systems only. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commanding Officer, Naval, Air Engineering Center, Specifications and Standards Department, (ESSD) Code 93, Lakehurst, New Jersey 08733 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

d. Transmission of an internally generated 1,020 hertz (Hz) tone on any selected channel.

e. Automatic relaying whereby interconnection of two radio sets results in automatic transmission on one radio set of either normal or secure voice signals being received by the other radio set.

f. Control of the TSEC/KY-28 secure voice equipment.

g. Remote display of the radio set operating frequency and preset channel number - AN/ARC-159(V) Systems only.

h. Guard channel precedence operation whereby an external control automatically turns the radio set on and tunes it to the guard channel - AN/ARC-159(V) Systems only.

- The equipment covered by this specification shall consist of the following items:
