Yes, and currently being called "x2" (until it becomes "Phase II" standard.)Also remember that this version of Motorola's TDMA support is actually at this moment a proprietary implementation of the Phase II "standard" - which hasn't been officially ratified yet.
DUH!!!Yes, scanners can be manufactured that would pickup TDMA signals. The problem would be if the 'channel' was encrypted or scrambled. The Feds take a dim view of anyone listening to an encrypted signal without the proper authorization. But, in general, if a modulation scheme can be received by the intended recipient then it can also be monitored by unintended recipients.
