[SOC] Strange phenomenon occurring ....

Wed May 6 12:12:56 EDT 2015

i also have W8JK's book but never read to it anymore. (reading the
universe in a mirror right now)

passive radar? it that like greaseless butter?

mike w7dra

i must be SOC because i get SOC emails

helix as a directive antenna?

we used element modulation (varied the length of the elements to slow the
wave down on long yagis (100 elements) and sometimes tried "twisting" the
yagi for the same effect

back then i was more interested in figuring out how to catch a student
nurse or an home econ major...........
