Hi, I would be interested in participating in the design of the PCB you
mentioned. It would be more circuit level than tracing/layout level. I
have a master degree and am eyeballing this RF design area.
Also, if you guys know about cheap/wasy online pcb makers and software
solutions? I have never done layout work before. I heard about
pcb123.com which have their own free layout software. Also, linux has a
free pcb layout software called simply "pcb".
