My good friend Marshall designs vlf antennas for the military and has worked on NAA. In fact Marshall worked with Dr. Wundt, the fellow who built the Goliath vlf antenna in Germany in WWII and was later brought to the U.S. in Operation Paperclip. Wundt did the original design for NAA. Great stories! 73 Warren On Sat, May 14, 2016 at 12:16 PM, Chris Wilson wrote: > Hello Warren, > > Saturday, May 14, 2016 > > Fascinating stuff, thanks for posting that, shame there are no photos, > do you know where one might see some photographs of these giants? > > > Best regards, > Chris 2E0ILY mailto:chris@chriswilson.tv > > > >> Yes NAA uses a saturated core reactor: >> http://coldwar-c4i.net/VLF/design.html > > >> > > -- 73 Warren K2ORS WD2XGJ WD2XSH/23 WE2XEB/2 WE2XGR/1
