For example, firefighters at the Los Angeles International Airport came to us several years ago because they needed to clearly distinguish and communicate on six radios simultaneously! Their environment requires that they monitor and respond on two tower and multiple ground radio channels. Setcom's solution was the System 1600, a four-person,
six-radio system that allows each crewmember to individually select the frequencies he monitors and to which he responds. Robust metal housings, shielded cabling and advanced circuitry prevent cross-talk between channels.
