From the introduction: Rules for sensors and communications in Fantasy Flight Game’s Star Wars RPG’s are sparse and sometimes contradictory. Rules described by one piece of gear are often quite different than those described for a similar piece of gear. Some gear or attachments makes others completely obsolete and non-desirable. Communications or “comms” of huge, expensive vehicles are limited to 100’s of kilometers while a cheap, portable comm can reach across light-years. This document attempts to alleviate these problems without making too many actual changes or, “house rules”. Yet, some are still needed. But, most of this document still involves clarifications and examples when possible over changing of the rules-as-written, or “RAW”. Don’t be scared of its length. The rules below are actually quite limited. The explanation and examples make it lengthy.
