The company that provided the equipment for the Puyallup system says they have 3 transmitters all on 1580. The Information Station Specialists (ISS) web site is a wealth of great information on TIS/HAR systems. It includes a partial list of National Parks that use ISS supplied systems including the call signs which are normally difficult to find. And it has a great state by state list of the many TIS stations that it has provided equipment for across the US. The web site is at http://www.issinfosite.com. The ISS web site mentions the following systems which they confirm to be synchronized: Boca Raton FL - 2 stations on 1620 Miami FL - 3 stations on 1680 Pinellas County FL - 5 stations on 940 Naperville IL - 3 stations on 1610 Battle Creek MI - 3 stations on 1610 City of Brunswick OH - 2 stations on 1700 Putnam County TN - 4 stations on 1610 DOE - Pasco WA - 4 stations on 530 They list a number of other systems with multiple transmitters on the same frequency but don't confirm whether they are synchronized.
