The RA-7203C receiver unit is a complete stand-alone receiver  with built in power supply weighting only 1.7 kg.

The receiver use the most powerful digital  signal processors to perform the intermediate frequency (IF)  and the audio frequency (AF) filtering. In addition, all the  modulation and demodulation tasks are performed in the  signal processor. This means improved product control, less  tuneable parts and improved reliability.

The RA-7203C receiver has programmable output frequency and output level for squelch operation. By using this option the audio line interface might be limited to 4 wires only.
