ABSTRACT:
Tone signal (34a) having a reference frequency (f) which is produced by the tone signal generation device (34) at the transmitter part is transmitted, via transmitter device (32), antenna (31), aerial line, antenna (32), to the reception sector (12). Then, the received tone signal (12a) is compared by the frequency correction circuit (A) with the preset reference signal (f), and according to a result of the comparison, a frequency produced by the reception sector (12) is corrected. That is, an error produced between the transmission frequency by the transmitter (32) and the reception frequency by the receiver (12) is apparently canceled. Thereby facsimile data can be transmitted so correctly to the receiver part so that the facsimile communication with use of radio SSB system can be successfully applied, although there may be an error between the transmitter frequency and the receiver frequency.
