It is probably possible to place a fraudulent radio telephone call from an amateur radio station, but it's easier (and just as illegal) to use a cellular telephone set. When a valid call-attempt is made, the cellular telephone set transmits its phone number and its serial number (an electronic PIN), as well as the number dialed by the user. The local cellular carrier is supposed to validate the combination. A cellular telephone user who fiddles with the proms or other administerable memory can probably impersonate a valid subscriber. It may be high tech, but it's functionally equivalent to stealing and using another telephone subscribers calling card number. -- Dave Levenson Westmark, Inc.
