I am doing Well Depths on this build. You're seeing the unit face down in this photo, and each block is cut to well depth. So the face of the tiles should be at well depth within 1/16" (the blocks are accurate to 1/32", but the whole unit has a little flex to it).
I can't imagine how QRDude could be more useful at this point. It really does everything I need to conceptualize and calculate. I really think the only thing that could make it easier at this point, is if I could put in dimensions and have it figure out an optimized QRD for X by X dimensions with a couple minimum data points.
Oh, I do wonder if there is a calculation for the time delay introduced by the QRDs. I was thinking about something Ron Sauro and SAC said about working with time above the critical frequency, and I'm wondering how to figure out the time scattering effect of a particular QRD. I'll probably have to call those guys on that and see what they say.
All in all, QRDude is what got me to this point. Well, that and about $120 in MDF.
