    • A multifunction radio for receiving radio signals from and sending transmissions to multiple radio systems comprises an antenna and a transmit/receive switch coupled to the antenna. The radio further comprises a receiver section coupled to the transmit/receive switch and configured to receive radio signals from one or more multiple radio systems. The receiver section includes a digital downconverter configured to digitally downconvert radio signals sent from one or more of the multiple radio systems and a digital signal processor coupled to the digital downconverter for processing the downconverted signals. A transmitter section is coupled to the transmit/receive switch and configured to generate a transmission signal for reception by one or more of the multiple radio systems.
    • 用于从多个无线电系统接收和发送传输的无线电信号的多功能无线电设备包括耦合到天线的天线和发射/接收开关。 无线电还包括耦合到发射/接收开关并被配置为从一个或多个多个无线电系统接收无线电信号的接收机部分。 接收器部分包括数字下变频器,其被配置为数字地下变频从多个无线电系统中的一个或多个发送的无线电信号,以及耦合到数字下变频器的数字信号处理器,用于处理下变频信号。 发射机部分耦合到发射/接收交换机并且被配置为生成用于由多个无线电系统中的一个或多个接收的传输信号。

    • An audio system may comprise a transceiver configured to receive, detect, and transmit audio signals on a first channel frequency and to receive and detect audio signals on at least one additional channel frequency. The at least one additional channel frequency may include a second channel frequency. The system may include a controller configured to output a first audio cue while outputting audio signals received from the at least one additional channel frequency, to output a second audio cue at a time when the controller begins outputting an audio signal received from the first channel frequency, and to output a third audio cue at a time when the controller begins outputting an audio signal received from the second channel frequency. The first, second, and third audio cues may be different from one another.
    • 音频系统可以包括收发器,其被配置为在第一信道频率上接收,检测和发送音频信号,并且在至少一个附加信道频率上接收和检测音频信号。 所述至少一个附加信道频率可以包括第二信道频率。 该系统可以包括控制器,其被配置为在输出从至少一个附加信道频率接收的音频信号的同时输出第一音频提示,以在控制器开始输出从第一信道频率接收的音频信号时输出第二音频提示 并且在控制器开始输出从第二信道频率接收的音频信号时输出第三音频提示。 第一,第二和第三音频提示可以彼此不同。
