OpenHPSDR
The HPSDR (High Performance Software Defined Radio)[1] project uses a 16-bit 135MSPS analog-to-digital converter that provides performance over the range 0 to 55 MHz 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. Interface to a PC is provided by a USB 2.0 interface. The project is modular and comprises a backplane onto which other boards plug in. This allows experimentation with new techniques and devices without the need to replace the entire set of boards. An exciter provides 1/2W of RF over the same range or into the VHF and UHF range using image or alias outputs. The HPSDR project is open-source for both hardware and software. A Wiki provides frequent updates as to project progress.
The HPSDR hardware uses a high speed analogue to digital converter for direct conversion of the received or transmitted signal.[2] The signal information (now in digital format) is processed by a computer to recover the desired information (voice, morse code, teletype, etc.).
