Electronic Message Units
Sometimes, when voice communication is not possible or is considered not-secure,
an Electronic Message Unit (EMU) is used in combination with an existing
radio set. Such EMUs are commonly used in combination with
military radio sets and generally employ some level of
cryptography.
Over the years, many different EMUs have been developed, with a varying level
of crypto-security.
An EMU is also known as Digital Message Device (DMD).
