DH107

The DH107 was a comlink developed by Herzfall Corporation during the Galactic Civil War. They were also fitted as internal comlinks in stormtrooper helmets. The DH107 employed linked encoding sequences, giving the comlink the ability to change communications frequencies every few seconds and keep the entire unit synchronized at the same time. The coding sequences were automatically deleted if the helmet was removed without pressing the control stud of the comlink first.

After operational problems were discovered with SoroSuub Corporation's DH77 headcomm—namely that explosions could create dead zones in which DH77 transmissions were lost, and contrails from TIE/LN starfighters knocked out DH77's with a range of three kilometers—Herzfall Corporation developed a comlink that was less susceptible to interference and signal interception. All Imperial Army platoons raised after the Battle of Yavin were outfitted with the DH107.
