I believe a study of ionospheric non-linearity (Luxumberg Effect?)
was made 30+ years ago at Syracuse University.  They built
an array of several 3L Telrex beams at 13.9?? MHz to excite the
ionosphere.  

WA3HRV (now K3RV) was at Syracuse then and through him
I was able to purchase 5 of those antennas around 1971 or 72.

I never did learn the results of the study.
