Say telephones and cellphones go out. Will HAM radios or CB's be the best form? Breaker 1 9
the privacy codes actually work the opposite way. it's just an ad on to the squelch system to keep you from having to listen to other users. when you have it turned on your radio will not come off squelch unless it gets the tone from somebody in your group (or somebody else using that same tone). but your commo is in the clear and anyone using the radios with the privacy codes turned off gets to hear everything. so far i think if you want some scrambled commo your going to have to go with some high dollar ham gear. but i think with the current level of electronics a small radio with secure could be built cheaply, but i bet the FCC specifically prohibits scrambled commo on the gmrs/frs frequencys. you read some more on the privacy code/ squelch system at http://en.wikipedia.org/wiki/CTCSSYou can have as many as you want (of identical units) programed with privacy codes so that only members of your group can hear the conversations, which is something that you can't do on a CB as far as I know.
