Discontinued SDR-3000 Software Defined Receiver

The SDR-3000 is a DSP digital demodulation radio based on the SDR software defined radio architecture. Featuring a 192kHz wide spectrogram and waterfall display capability with 16 bit sampling for a highly dynamic receiver with CW, AM, SSB and FM demodulation. The whole unit is housed in a full aluminium CNC casing with a 4.3" 800x480 resolution high brightness IPS LCD display, while maintaining a small and compact body
