Introduction -- What's It All About?
The HPSDR is an open source (GNU type) hardware and software project intended as a "next generation" Software Defined Radio (SDR) for use by Radio Amateurs ("hams") and Short Wave Listeners (SWLs). It is being designed and developed by a group of SDR enthusiasts with representation from interested experimenters worldwide

The rationale behind the project is to break the overall design up into a number of modules. Each module is designed by an individual or group and connects to other modules using a pre-defined and common bus -- rather like plugging boards into a PC motherboard.

The Images below show the Hermes Lite in assembly and complete and running. Images show the SDR running on open source software HPSDR fully configurable withe the HL and Spark software which offers a wide number of digital formats including a CW function both for automated sending and decoding with digital text display.
