"Unwashed" hams and "washed" hams

... Hello, Roy and all. While I aggree with the above I think one has to keep in mind that 50 years ago there weren't software MoM (e.g. NEC) and FDTD tools around to implement calculations that don't lend themselves to pencil-and-paper calculation. As a result back then there was considerable "art" (I would call it engineering) involved in antenna design. Hams, too, were coming up with many practical designs back then as well as now. Practical experience was important then and still is. ... John Wood (Code 5550) e-mail: Naval Research Laboratory 4555 Overlook Avenue, SW Washington, DC 20375-5337 Your points are well taken here. However, I do believe there is a lot of "art" involved. We don't even know what our signals are really composed of. We don't even really know how propagation and movement of our signals takes place though the medium which transports them; And, indeed, we don't even know the medium through which they travel ... if not for brilliant and "artful" men, this never would have occurred. If this all does not make men stand in awe and wonder of these artistic accomplishment and beauty of engineering achievements, I just don't know what would! Our imaginations have allowed us to reach out and use powers far beyond the horizons of our vision. Sometime in the future, we will even refine all of this ... as our vision(s) become clearer.
