EMU
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).
