from what ive heard
its not encrypted, its 2 radios in one. reciveng channel to speaker, mic to sending channel

I doubt that they have gone to digital without encryption - thats the whole idea of digital. I'm no expert but I also doubt they send on one channel and receive on another.

What you are refering to Spike is called duplexing the radio transmits on one frequency and recieves on another.
The channel that ihe radio sends on is recieved by a central radio with an antennea that is exteemly high so that is has a greater range than the moblie unit does and then retransmits the signal on the other recieve channel , thus giving a much wider range than it would if just one unit to another.
