LOCATION CODES

[Straight Shooter]

Been wondering for a while now , when tshtf how could we contact fellow preppers ( from this site say ) if i needed help or i could give help how would we know where to go , inorder to make contact. Do we have a system in place ? i am from south wales BUT where ? if we had say a rough (close but not to close ref ) in my case my comms is a CB ....lets say barneyboy lives at A26s11 and i head to that location so we could meet up, lets say my callsign is SSA12s4 could that work? A=area s=sector......ss=straightshooter area12section4. any thoughts out there...think NR put something bout codes for radio callsigns could this be used alongside where you are located
