 Its sampling and synthesis bandwidth (30-120 MHz) is a thousand times that of PC sound cards, which enables wideband operation.The HPSDR (High Performance Software Defined Radio) project uses a 16-bit analog-to-digital converter that provides performance over the range 0 to comparable to that of a conventional analogue HF radio.The receiver will also operate in the VHF and UHF range using either mixer image or alias responses.
