NUE-PSK Digital Modem

The dsPIC33F128MC706-based NUE-PSK Digital Modem is a portable PSK31 interface. The stand-alone, battery-operated system enables PSK31 field operation without the use of a PC. The novel system includes two LCDs. LCD-1 is a 4 × 20 character display for transmitting and receiving text data. LCD-2 is a 144 × 32 pixel graphics display for showing the FFT-generated spectrum of the audio passband.
