Hello, I found some very interesting stuff about the use of a 4 square k9ay by the SP3KEY club. Unfortunatly only partial information. Is there anyone who has the emailadress from either sp3key or the builder of the system sp3rbr? I am looking for the schematics, and dimensions (phasing cables etc) of this system. Thanks!
