Many ships , both naval and commercial, have covert activities by people who code and decode a continuous wave with an archane on-off device. To divert investigators they refer to the key to their my
Thank you for the information! I knew that the 500KHz. Watch was discontinued but there are many other maritime frequencies. A retired navy officer I used to work with told me about nine or so years
This reminds me of a post on a Masonic list. Some one took offense at the word "pilgrim" used in a context with Brother John Wayne. The reply started out with something like this: "John Wayne was an
Info might be found in old books. Books were a crude system of recording data without use of magnetism. Invented about 1400 but long since redundant. No satellite communications!!!! We would have to
I thought things were getting a bit esoteric for this reflector. Came into the discussion part way through after reading a huge backlog of email after a holiday .... and you know how things are :-) D
Hi Andy, I don't quite know where EMP crept into the discussion. Dick's original E-mail to this reflector was about a paper on Radiation Belt Remediation. http://www.physics.otago.ac.nz/research/spac
My understanding of EMP Nuclear bombs - gained from documentation from the 1960s/70s, was that these were exo-atmospheric bursts designed to generate huge impulses at the ground due to Compton scatte
That system (HF radio) became obsolete due to very high costs of training and employing the necessary human operators. Nowdays the frequencies formerly used by HF radio have been silently re-allocate
Mike. G3XDV == but meanwhile, a) we have all become addicted to "bandwidth", and b) many of us (particularly the Military) have learned the benefits of obfuscation and content-free explanations, and
No satellite communications!!!! We would have to find some kind of alternative way to transmit signals round the world. Now didn't there used to be something called HF? Where on earth can we get lots
Hello Dick, The same issue popped up on an other list last week. After a lot of turmoil it dawned upon some knowledgeable people that the scientists had mixed up transmitter power and radiated power

I seem to remember that ill-thoughtout "experiments" like this have been mooted before. Did not the Americans want a one stage to improve the ionosphere by tipping a lorry load of thin wire dipoles i
Hi Dick, 1. Was there not a similar scare a few years ago about ionospheric warming casued by HAARP experiments etc. ? 2. Pat g4gvw makes very valid objections in his E-mail, matters which seem to be
Hi Dick, scary stuff! Some more of Craig Rodger's work can be seen at http://webflash.ess.washington.edu/ which has a nice VLF active antenna design. Mike ZL4OL
