I am mostly local in my communications.. I'm a certified amateur radio person here in Canada.. with my basic with honours and advanced which pretty much gives me the most privileges a person can have on the amateur bands up here. I've been studying for nautical and aeronautical, and think I will keep doing that, not overly complex though. I'm able to build radio devices and have some spare parts to build both transmitters and receivers... mostly low wattage though.. I also have a pi which oddly can be used for long distance communications of low bitrate.. none the less I have some radio projects. I'm not overly concerned though as I'm mostly a solo prepper. My sat phone could also be used for some communications if the network was intact... I know all about the stuff.. but really am of a local nature except the repeaters... and of course I know how to take over the microwave, am/fm, and television systems in an emergency.. but really I do not expect nuclear war tomorrow and if it doesn't happen when missiles get sent into Syria.. it probably ain't going to happen any time soon.
None the less I could create communications or take over any local communications facility without much difficulty.. but as long as there are cops up here.. it is likely a stable situation which would not require that resort. If the police and military don't have an interest up here I'm pretty much on call up to help reduce risk to life and property up here.
None the less while I prep I do not expect.. and while it doesn't hurt there is a fine line between likelihood and that which is closer to fantasy.
