Well, I'm no techie when it comes to the workings of CDMA. I know only that a code is assigned to a particular transmission, and the code will vary over time. A pure CDMA transmission--from one CDMA user to another-- will be difficult to monitor, but not impossible. Initially it was thought that the CDMA code was virtually impossible to crack in a short time period, but further research has shown it can be done. Again, it's difficult, but I thank you for letting me know that even my CDMA conversations can be monitored. Now, where's the Tums? Art

To do over the air monitoring is very hard to do cuz you need to be equiped like a mini basestation. Since as the caller moving around the code channel, the scrambling code will always change. So unless you just outright recording all the noises in the air(while following the caller all over the place) and go back try to decode them, all you hear in the air are noises. Let alone if you also have encryption on top of your CDMA call. So the easiest way to monitor you is via sniffing on the landside with the help from the carriers.
