We all know that the internet is a mixed blessing. Lots of good stuff, but also
very bad if one seeks it out. I find it quite amazing, to watch a VOA or
similar class transmitters being brought up, and put online. I've lived no more
than an hour away from Bethany, Ohio which many know was a VOA site until 1994.
Near by WLW in Mason, Ohio is on the air today covering 37 states at night, and
9 in the daytime if I recall correctly, with 50kw on 700kc.
There is quite a history there, back when WLW ran 500kw! That figure is hard to
wrap my brain around, as we are talking brute power, before any sort of antenna
gain came into play. The sheer magnitude of such an operation, and the fact
that this amount of RF could be generated in one place back when they did it,
is quite a feat in my opinion.
Back in 1964, our senior EE class got to tour that site. We'd just
finished our course in transmission lines, so it was a wonderful lab!
I'd been a ham since '55, so I knew about Rhombics (of which there were
around two dozen) but the two Sterba Curtains were new to me.
