A radio receiving apparatus is used at a sporting event to provide a spectator with additional information and contact with the participants in the event. In an automobile racing event, each of the automobiles can be equipped with a two-way radio for communication between the driver and the crew as well as with a telemetry transmitter for sending data concerning the operation of the automobile. The telemetry data is combined with other information relating to the car's involvement in the race and this data is combined to produce parameter data. A hand-held receiver receives both the audio conversation and the parameter data for one of the selected cars and produces audible sounds and concurrently produces a display of a graphic image on a screen with information derived from the parameter data. Thus, the user of the receiving apparatus can both hear a selected driver and at the same time see a display of performance information about the car and driver in the race. The receiving apparatus can comprise either two radio receivers, one for the audio signal and the other for the data signal, or a single receiver that receives a combined audio and data signal that is separated within the receiver to produce the separate audible and graphic displays. Before the sporting event commences, an electronic file can be automatically loaded into the receiving apparatus to preprogram the apparatus with all of the frequencies for the participants, thus allowing the user to easily select and move between the participants to more fully participate in the sporting event. The receiving apparatus can be a stand alone unit or a module used with a portable electronic display such as a personal digital assistant.
