Abstract: A portable communication apparatus and method includes a portable AM transmitter assembly and antenna operably connected for broadcasting an AM signal to standard automobile radio receiver, such as on a travel information station frequency of 1610 KHz. The system is particularly constructed for mobility, durability, simplicity and ease of use, making it well adapted for use in emergency situations as well as for the broadcast of general community or travelers information at fixed or temporary locations during nonemergency times. For example, the entire present assembly 20 can be constructed with a total weight of less than about 130 lbs, allowing it to be easily moved by individuals and by low-weight-capable small capacity vehicles such as planes or boats or pick-up trucks.
