I AM considering my own radio design. I need to solve some basic housing
issues (not for the radio, for me) first, but I've started by reading a
few books on DSP for communications design, and even bought one of them
for about $100.00 to have it handier than the local university library.
I've also downloaded most of the TI DSP design library for study.
There is more than one radio structure that can be used and the SDR1K
and Orion represent opposites. I think there is a better scheme, but I
have yet to prove its practical with enough dynamic range for HF ham
band use. In a one man show, it takes time to produce proven good code
and new hardware. I lean towards using an AMD or Intel Pentium style
processor because I can buy boards with CPU, I/O, and RAM far cheaper
than I can buy DSP boards and the later Pentium families do have DSP
instructions. That and I already have and use a compiler for them that
comes with a very fine debugger that may not be part of the tool kit for
the DSP chips. I can be very much more productive with existing hardware
than having to do ALL the hardware and software.
