[Premium-Rx] RFSpace SDR-14 digital receiver

[Jeff Anderson]

If you're interested in software-defined-radios, take a look at the HF SSB SDR
transceiver designed by Dick Benson, W1QG.  He describes it in the very last
article you'll find on his list of articles at:  http://home.comcast.net/~w1qg/
.

I've seen it in operation - very cool.   What's more interesting is that a
project that would typically have taken man-years to develop (if using
conventional software coding techniques), was done in a month (or so) using
Mathwork's Simulink.

The guts of the radio are the RF DAC & ADC, a (big) Xilinx FPGA, a TI DSP, and
an audio codec.  What could be simpler?
