Don't have one, but know two who do. Scramble, as I understand the meaning of the word, they don't. Last I knew, "Secure Clear" is simple frequency inversion, and can be defeated by: a $15 kit added to a scanner, or; tuning the freq on a single sideband receiver. I've even heard of individuals who had trained themselves, or been trained, to understand the freq inverted signal. Check out Cincinnati Microwave's spread spectrum frequency phones. I don't know if they use frequency hopping or direct sequence, but they may be secure against all but military and LEA types... and the really determined and accomplished hardware hacker.
