タ系のみの１系統モードとし。Figure 4 shows an 8D radio station equipped with an S system receiving system.
At a radio station, the receiving systems of one system and the other system (hereinafter referred to as master system and slave system) are synchronized and combined to improve the quality of received radio waves. If the wave propagation characteristics are good, in S11, it is sufficient to operate one system of the master system. Focusing on this, the system status display signal 8 drawn into the circuit 11 on the side of the receiver is 4 that indicates the reception level of the master system. Therefore, if the charge amount of the secondary battery is below the specified level and the reception level of the master system is above the specified level, the synthesis/switching circuit ms sets the mode to one system only for the master system.

The transmission system is brought into direct communication, and the switch 84 is opened to temporarily stop supplying the output power to the output amplifier 8z.

For example, in a system with a so-called N-to-l configuration in which there is one standby system for eight active systems, if the target for temporarily stopping the supply of power is applied to the active system, the output increase ma is switched off. The received level margin on the receiving side due to separation is reduced by the amplification amount of the output amplifier, which may have the effect of degrading the line quality, but the effect of reducing power consumption is significant.
