MAK

FUNCTIONAL DESCRIPTION

The Nary Model MAK is a four channel mobile unit designed to provide a compact, two-way radio installation for use in Naval craft, combat vehicles and other applications where space is at a premium. It is crystal controlled and designed for operation in the 2 to 4 megacycle frequency range. It can be operated from a 6 or 12 volt direct-current power source by using the proper associated power assembly. The essential control circuits can be operated from a remote location with the exception of voice-continuous wave and channel selection circuits.

RELATION TO OTHER EQUIPMENT

The Navy Model MAK is similar to Navy Model MO-1, differing mainly in the frequency range coverage.
