Hi Terry,

www.fpga4fun.com is a cool site.

It's time for me to get back into this.  I have an application that requires either a 200K sample rate, or undersampling for a
40K bandwidth.  Then I want to apply DSP.

Nobody makes anything to do that at any reasonable price, so it's time to make my own.  I remember that there was a generally
available 500K/S ADC a few years back.  I see ultra high speed ADC as the next step in SDR, and FPGA makes the logic hardware
much easier to do.

I had something cool going for synchronous AM, DSB and BPSK signal reception a few years back, but it was using a
block-converting FFT.  It was still pretty good.  Hal has suggested a streaming-serial oriented FFT.

And of course there is the never-ending parade of wierd logic analysis needs...

Also I have to remember to send in my dues again.
