[hpsdr] HPSDR - New Project - Cyclops - Spectrum Analyzer

[Richard Faust]

I like the concept and the product.  The block diagram suggests you would use Cyclops as a front end to the Mercury/Ozy combo, which would be very desirable.
 
I know enough programing to be dangerous but I am not a proficient programmer, so probably not the programer you would like for for support.  Probably want a game programer who knows how to go arround the M$ OS to get graphics speed improvements with out the spagetti code that M$ uses for the slow OS routings.
 
I would suggest, however, that you port the code [mentioned below] from the 'free' Visual Studio 2005 IDE[C#] to a neutral compiler that does not rely on M$ Net Framework of any variety and compile for Windows 9x[X86] on, Linux and MAC with binaries and source that would be understandable for all OS's.
 
Visual Studio # is far from 'free' as it mandates a 280MB overhead gorilla called Net Framework to run on X86 platforms and 610MB on X64.  My understanding is this software is primarily used for business networking applications [ie database] & I really doubt it contributes much to DSP except the welding of the software to the Windows OS.  Since you indicate below that you do not plan to modify PowerSDR, why not make this software compatable with more hardware?  Dumping Framework would free up the resources and speed up the machines for those who do not use [or want to use] Net Framework v1, v2, or v3, Flex hardware or PowerSDR.
