Simultaneous TACAMO VLF signals (17.8 and 27..2 kHz) were present a bit before 0300Z.?? The lower frequency signal displayed nicely on Laurence's grabber at http://kl7l.com/Alaska.html. The higher frequency signal would probably have displayed too but the grabber cut off above 25+ kHz. 73, Garry, K3SIW, EN52ta, Elgin, IL
