I said it a hundred times, get a garrison together — community rules … western military doctrine always maintains that only troops can hold ground…

This is idealistic and not my plan exactly but its an idea that can be applied elsewhere.

I would say the ideal in suburbia is the close off your street at both ends with a barricade ( we have this already ) .. get everyone in your street on board … link all the houses with radio or field telephones … establish a central meeting hall and guard house to coordinate everything, and provide a central kitchen, and central alarm should everyone need to wake up at once .

Dig the road up around the block to about 2 m deep and pile the rubble on the inside to form a parapet … use what you can to make a wall … cars … sand bags .. roof sheets with gravel whatever .. this is really just a trench to defend from. make a single entrance where the road is OK …

Home made Field telephones in a survival situation

Field telephones are one of the best and simplest systems of communication in a base of operations.
communication is Key to early warning and defense strategy.

Field Telephones are best used as a point to point communication solution or a simple “jack plug” switch board can be made with a little skill and then a person to man the switch board – if you require a system with more then 2 points..

They were extensivly used during both world wars and in Vietnam for secure communication.

I am not going to detail exactly how one would create the field telephone — but lets just say its not exactly difficult, the detail i will give is that on microphone and one speaker must obviously be at each end ( plans for making these yourself below although store bought is probably better if you build these before you need them )

I have included a basic circut diagram above I just drew up quickly, this will be what a single phone looks like – that plugs into a switch board, to have a simple phone that only have 2 ends then replace the jack plug with another bell, switch, mic and speaker.

__The Switch Board__
a simple switch board can be made by a few jack plug sockets, low voltage bulbs or leds, and jack plugs , the concept is for each “extention” you need a socket to plug the long line that goes to the phone into – another socket to plug another phone into wired in parallel and an led to indicate that its active, a third socket can be added in parallel to allow an operator to “listen in”, and a Lead with a plug on, this lead will plug into to other sockets to connect phones to others , each phone needs each of these i mentioned, it is best to make the sockets for each in a numbered column
so that you can keep track of the cables.
