Right. Can a radio with DSP be called a SDR? I have a FT-897, it has an audio DSP with autonotch, noise reduction, different filters and could be called a SDR, but a very primitive one. Myself I would not call it a SDR. The fact I can control it by software to tune, change band, mode ... does not make it a SDR either. IC-746 and up, Ten-Tec radio are SDRs. For Ten-Tec you don't even have to send it back to upgrade the firmware. > > Verilog and VHDL are programming languages that can run on your PC or > define how a FPGA functions.

A rig with microprocessors to control the display, read the different buttons, read the VFO encoder is not a SDR, but there is software in there. The same for a FPGA, it all depends on what it does. For example if you implement a DDS in the FPGA it does not make the rig a SDR. You can even have a FPGA reconfigurable on the fly while using it but it won't necessary be a SDR. You should give an example of what you intend to implement with a FPGA. Jean-Claude PJ2BVU ------------------------ Yahoo! Groups Sponsor --------------------~--> Get to your groups with one click.
