That’s true. The prime virtue of Morse Code is that it can cut through noise when nothing else can. So if you can learn it so much the better.
As i recall, at one time Uncle’s fall back comm system in extremis was CW radio using Morse Code. I don’t know what it is now. I think one watt will get you across the country.
I have a background in military communications...and while it's been awhile, only the technology has changed. Laws and capabilities remain nearly the same.
1. Ham Radio - Your location will be known within 15minutes of being identified as a broadcast they "want". To beat them, you must keep open a "listen/broadcast" channel. NEVER broadcast for more than 2-3minutes every 8 hours. NEVER.
The telephone network essentially belongs to Uncle Sam. The Defense Communications Agency will seize it as critical infrastructure at Declaration of Emergency. However, they'll probably just listen there. Telephones are critical for basic societal function. Just know they'll be listening to every call with machines looking for "key words". Learn a code of euphemisms to beat them...but if you ever do anything to get on their "list" full-time, euphemisms won't help. Then the humans will be listening.
As for the internet, ditto. It can be seized and it can be effectively monitored. Know with certainty there is AT LEAST a machine reading every post of Free Republic...and humans scanning the juicy "high interest" postings spit out by the machines.
Whenever you consider joining together with other like-minded people, know this. There are thousands of FBI/BATF etc. that have infiltrated most "militia" groups...and their definitions of whom might be a threat grow daily. ALWAYS and ONLY collaborate with family and friends you've known for a very long time. Keep that "cell" secret...don't talk, don't advertise. But DO meet and work out your contingency plans face-to-face, without electronic communications.
