I think I was in error when I identified the Annapolis site as an ELF
system. (it's been a long time). I believe it was a Very Low Frequency
(VLF) system, used for the same purpose but operated at slightly higher
frequencies. The antenna structure was very different than those described
at the Wisconsin and Michigan sites and basically transmitted a ground
wave.

VLF or ELF, it was still a damn high climb. ;-)
