Abstract

ABSTRACT OF THE DISCLOSURE

A remote broadcast vehicle does not require any setup time, may remain fully enclosedand locked while in operation, and which prevents the ingress of moisture and otherweather. The vehicle may includes a player for pre-recorded audio programs, a radiobroadcast station receiver, wireless microphone and wireless remote control, mixer,cross-over, amplifiers and speaker assemblies. The system may further be used to up-linka program to a base radio station, and provide full programming capability. Additionally,a tuned port speaker system is disclosed for broadcasting low frequencies through thevehicle wall. Several different vehicle embodiments are illustrated.
