CBP has a VHF repeater system throughout Florida. ICE also has a VHF repeater system throughout Florida. These are separate systems that are not connected with one another. The Florida CBP system is designed in such a way that allows the end user to select either encrypted or clear transmissions. The Florida ICE system is designed with 100% strapped encryption in all of their repeater channels and most of their simplex channels as well. ICE users do indeed have access to the CBP system and while on that system, can select clear or encryption. So if you have heard ICE in the clear, it could only have been on the CBP system, but not on the ICE system.
