PROBLEM TO BE SOLVED: To enable communication with a distant place, without any problem with only at a single frequency by digitally storing an audio analog signal from radio communication equipment on one side, reconverting that signal into an audio analog signal and re-transmitting it to other radio communication equipments. SOLUTION: At a voice recorder unit 14, an AF audio signal from a transceiver 60 connected to a radio wave repeater 10 is converted into a digital signal, under the control of a CPU 12 and recorded in a RAM 52 for the voice. Besides, the digital signal, recorded in the RAM 52, is reconverted into an analog signal under the control of the CPU 12. That signal is reproduced at an analog AF signal input 64 of the transceiver 60, connected to the radio wave repeater 10. |
