Seems OK to me. The files are Gerber's and other schematic info, so that you can get your own boards made and build them as required.

However, as I've said before, there isn't much additional effort required to build an LZ1AQ type circuit, but the improvement in performance is substantial.?

Apart from the novelty of building something, the PA0FRI, and the G8CQX it is based upon isn't that good, and personally I wouldn't bother.
