If you didn't bother to order the first edition then you are missing out on some damn good information .
Mr. Sparks starts out with some old time methods of communication by field phones, wired together like in WWII and even a way to eavesdrop on phone lines using barbed wire!!
I seem to recall someone who might be interested in that little bit of trivia.
There is also mention of ways to communicate when the grid goes down, phone systems that require no power to operate that can still be obtained and recommendations for the equipment to purchase.
I will be the first to admit that quite a bit of this went right past me as I have never been a comms kind of guy and lists of frequencies make my eyes glaze over.
That being said, there is a great deal of very useful information crammed into the 43 pages of this pamphlet sized publication!
It can and should be saved and used because it has some good reference materials in it and once you do get some kind of radio equipment there are those lists of frequencies I mentioned that will be very handy to have in a format small enough to throw in any bag or pack without having to worry about space or weight.
Some of the older phone info I am familiar with as I have in the past run into some phone system information from a pal that retired from the phone company and have played around with older phones and the networks they connect to.
Land line phone systems were actually quite simple affairs for those who remember them.
Land line phones as they are called now, are getting increasingly scarce due to the explosion of cell phone technology but the infrastructure is still there, just waiting to be put to good use.
My hat is off to Mr. Sparks for putting together a very useful collection of options to look into with this publication. His review of the Termin-8r hand held radio is also helpful to anyone looking into a modern set for group communications.
I see a yearly subscription is 27 dollars, a pretty good deal for the priceless information this could prove to be in the future.
I urge you to swing by and check out his place and if you are the least bit interested in OPSEC communications then I can't recommend this guy enough.
He also has classes you can attend to get serious information and hands on training in electronic comms and field craft.
