  1. Can you comment on the advantages or disadvantages of a Book Cipher (using word position on pages… i.e. using some given title, 48-37-12 means on page 48, on the 37th line, the 12th word is “tomorrow”…
    It seems like this would be an almost unbreakable code, even with super computers.

    1. Finding the words that you need to build the message could take a very significant amount of time. The book that you chose may not even contain the words necessary to convey the particular information that you wish to convey. An obscure out of print dictionary might be the best option – if you can find two or more identical copies.

      For absolute security one time pads are your best bet.

    2. If, instead of the entire word that 48-37-12 equates to, you only used the first letter of that word, then encoding and decoding would go much quicker and you wouldn’t have to hunt for the right word, only the correct first letter of a word.

  2. If your people can make it to Nevada via the 15, it should be pretty clear sailing NB on 95. I would take 127 north from Baker to get to 95 to avoid what would be a mess in LV.

    They could take the old road (Lucky Boy) site south of Hawthorne into Bridgeport or go north at Fletcher and take 208 to Holbrook Junction the south on 395 into Walker/Coleville. They would have to pre stage a fuel re supply stop or carry enough with them. It would take some navigation but is very doable, although winter snow could be an issue.

    Prearranged check in times for HF NVIS using 40, 60, or 80 meters should keep you in touch as they travel. They can pull over, stretch a wire antenna 10-15 feet off the ground, check in, and be on their way.

    The southern route would be the easiest. I don’t think the MWTC would be closing 395 for a while. You would know more about that.

    OBTW, excellent article. It is a knowledge area that I don’t know much about. Good luck “neighbor”.

  3. Thanks, East Sierra MTN MAN!!! I try to produce information that may help those who lack formal training. If My Network were to remain in place, we would use the Book method, My method intends to use a BRIEF message, via an open source communication format for QUICK/Brief transmissions, while On the Move (OTM) or, “Oscar Mike”
