A communication device (100) including a receiver (110), a demodulator (120), a frequency dependent LF amplifier (130) as well as a frequency dependent decoder (150) receives a HF signal (105) onto which speech information and data information are modulated on a single carrier. The LF signal (125) provided from demodulator (120) includes two separated frequency bands for speech and data. The amplifier (130) makes audible the speech via a speaker (140) and the decoder (150) evaluates the data information, displays the same at a display (160) and controls the amplifier (150,155), respectively.
