[hpsdr] DFC

[Henry Vredegoor]

Hi All,

What I understand from the Teamspeak discussions is that one of the big 
advantages also is that the development of software is "easier" for PC 
related software than  for FPGA software. (long compile times and 
critical timing issues etc. for FPGA)  and that a many more people know 
how to develop software for a PC than for FPGA's and so many more people 
could contibute.

@Helmut:  I thought 10 GBit was mentioned as a possibility?

73,

Henry - PA0HJA
