Dear QRPopsters:
I'm introducing Ward Harriman, AE6TY, to the group.? If his name is familiar it
may be because you have read his three-part article in QRP Quarterly, "Making a
Software-Defined Radio for the QRP Enthusiast."? The final installment is in the
current issue.
Ward also enjoys tinkering with antennas and other QRP equipment.? He's only
been a ham for a few years but he is clearly making up for lost time.?

Ward,
Great articles on SDR. I would love to talk to you about your project. I have a Tony Parks SDR receiver that I have been experimenting with using a E-MU sound card and Rocky software. It would be interesting to see if a portable QRP rig could be built using a DSP chip and a small uP, a la NUE-PSK modem but with SSB and other modes.

I enjoyed the articles and of specific value to me was the write-up about the education process around PCB manufacturing.
I'm working on building and all-smt SDR rx design with the objective of size reduction. (Nothing new here, but an interesting challenge) The design/manufacturing process is interesting and your experiences/notes are very valuable.
I can't agree more on your closing perspective of "not to put off building new projects because of some "barrier to entry"
I've had more fun recently, building things, than in the 15 years of ham radio before. We're certainly fortunate to be living in exciting times for rf tech development - given that a $10 SDR homebrew construction can now achieve the same level of performance of professional grade equipment - costing $1000s.
Being new to PCB manufacturing, I find the process of parts-selection a little cumbersome.
Especially the minimum-buy constraints for most of the SMT parts.
What is the trick to not have to buy 500 lots and to have the PCB layout dictate the parts selection and not the other way around?
Wonder if you have some tips on parts-selection process when using digi-key (or another vendor)?
Have you worked with any of the FPGA dev boards?
The Xilinx board looks like a decent starting point?

For those interested in how SDR tech is revolutionizing the comms landscape, I found these write-ups really interesting read:

| Hi Ward,
I was thinking about lunch time and if I remember correctly, Dave and a couple of others mentioned a similar time.
