Hardware specifications
 

FSK Convertor consists of a halfsize plug-in card for AT slot, completelyscreened and sealed for rugged industrial and military environments. Itcontains a 50dB dynamic range analog interface to cater for a wide varietyof audio feeds and a unique multimode demodulator for synchronous and asynchronoussignals, converting the audio by DSP technique. The interface design isable to cope with a wide variety of FSK two tone and multi-tone signalsfound on Short Wave radio (see below).

Two BNC sockets for the two input channels (diversity) and one audiooutput for a QBF test generator and DA output. No further power supplyis needed.
