October 8, 2015: I am still working on this, but I have been pretty busy with a few other things. I got the new circuit boards, and I also tested the flexible antenna with one of the old boards. It worked, but the antenna needed to be bent a certain way. I'm hoping it's just because of the messy attach of the antenna to a board that wasn't designed to have an external antenna.

I laser cut solder stencils for the new boards out of Mylar with adhesive. I plan to solder them up in the next week or so, at which time I'll have a sense of whether this is going to work.
