1. A mobile tactical device for enabling radio communications between a plurality of users, the mobile tactical device comprising:
a radio connection interface configured to receive a first communication having a mobile frequency from a mobile radio;
a first power detector configured to detect power related to the first communication;
a first frequency converter configured to convert the mobile frequency to an intermediate frequency after detection by the first power detector;
a frequency filter configured to pass the intermediate frequency when the mobile frequency is an assigned mobile frequency corresponding to one of a plurality of predetermined frequencies for talk groups and reject the intermediate frequency when the mobile frequency is not the assigned mobile frequency corresponding to one of the plurality of predetermined frequencies for talk groups;
a second power detector configured to detect power related to the first communication after the first communication has passed the frequency filter; and
a second frequency converter configured to convert the intermediate frequency to an assigned transmission frequency for transmission of the first communication.
