it's unlikely that any Globalstar phone message could be monitored directly because the CDMA system for encoding the voice makes it very difficult Art... let me ask you a question.. If someone initiates a CDMA phone call on one end, to a land line on the other, what kind of digital to analog CoDec is involved? Where is that CoDec located? You're quite correct about the difficulty outside parties have in listening in on a CDMA call because of the security measures involved. However, if your the central switch that is setting up the other side of that CDMA "handshake" at Globalstar, you have all kinds of ability to tap into that line. And any scrambler would likely be keyed in a DES encryption.. And that has a backdoor designed right into it for access by Government agencies. And there are a few other things about cell phones that I won't discuss... but suffice it to say that you can be tracked from cell to cell fairly readily (Kevin Mitnick anyone?), and even pin-point your position in some cases if you stay on too long.
