Hi Trystan:

My problem was that at the last moment I change from my house to Al's for the presentation. My office is in the basement and the extender I'm using started causing the Internet connection to drop out. Since that would be a disaster during my talk, Al let me set things up at his house. Things got a little confusing, but we muddled through.

I really enjoyed Ashar's talk as we are also working on an SDT. A couple of years ago, Al and I did a DSP board that connected to the uBITX, but it never really caught on. I think we made it too complex to add it to the uBITX. The new SDT will have mutlple boards with lots of "board real estate" and test points for experimenting. We will also do a book where each chapter will discuss a section of the rig, from antenna to earphones. Another thing we learned from the JackAl experience was NOT to use a resistive touch screen. Most QRP rigs do not have enough mass to activate a button without using the other hand to stabilize the rig. Ashar's rig uses capacitive touch...smart move! Also, he is using a large display where us "fat-finger people" can actually poke an individual button! And the RP has a mega-munch of memory and is clocked at 750mHz (I think?). Anyway, it was interesting to see what he's done with the uBITX in the SDT sandbox. I also admired the "cleanliness" of his code...good stuff!
