If a radio system is all digital then it is possible to use the same system
for MDT's, otherwise the MDT's will be on another frequency. Many of the new
MDT's are using different protocols then the earlier ones and no software is
available to decode them. It is also illegal to intercept MDT's because
of federal wiretap laws. So if you do it you are taking a risk and better burn
anything you receive.
