Encrypted microparticle multibank communicator
From Tardis Wiki, the free Doctor Who reference
An encrypted microparticle multibank communicator could be used to make contact with distant star systems.
The Lawkeepers of Pandrin V gave one to Trenix, disguised as a transistor radio, for him to use should he need to contact them during his time in witness protection in London 1978. (AUDIO: The Sinestran Kill)
