Mobile tactical radio device, system and method

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;
• a first power detector configured to detect power related to the first communication;
• a frequency filter configured to pass or reject the first communication after the first communication has been detected by the first power detector based on a frequency of the first communication being an assigned mobile frequency predetermined for a talk group;
• a second power detector configured to detect power related to the first communication after the first communication has passed the frequency filter;
• and
• a controller configured to cause the first communication to be converted to an assigned transmission frequency corresponding to the assigned mobile frequency upon determining that the first communication has been detected by both the first power detector and the second power detector.

A method of enabling radio communications between a plurality of users, the method comprising:

• receiving a momentary transmission from a mobile radio, the momentary transmission having an assigned mobile frequency corresponding to a talk group;
• detecting power related to the momentary transmission having the assigned mobile frequency;
• converting the assigned mobile frequency to an intermediate frequency using at least one frequency converter;
• detecting power related to the momentary transmission after conversion to the intermediate frequency;
• converting the intermediate frequency to an assigned transmission frequency using the at least one frequency converter;
• and
• setting the at least one frequency converter such that a communication received using the assigned transmission frequency is converted to the assigned mobile frequency for transmission to the mobile radio.
