PURPOSE:To identify immediately the propriety of use of the transmitter and the level of the line output, by carrying out a simultaneous display and via a pair of meters for both the reception part selected by the diversity-type receiver and the nonreception part which is not selected respectively. CONSTITUTION:The diversity deciding circuit 14 decides which is better the reception part 12 or 13. Based on this decision, the output of one side is applied to the voice amplifier 16, and the decision signal is supplied to the display controllers 17 and 20 each. Thus the display unit gives a lighting of color A at the part 12 or 13 which is decided nondefective by the circuit 14; while the color B is given to the display unit of the part 12 or 13 where the input conditions is inferior. And the color A or B is given in accordance with the decision of the circuit 14, and at the same time the change of the reception state at that time is displayed in the colors A and B via the reception level meters 18-22. In this way, both the propriety of use of the transmitter and the level of the line output can be identified immediately. |
