In performing their required duties public safety personnel from differing departments often need to communicate with one another using their in-car radios. However, in many cases, especially involving small departments, this interoperability doesn't exist.

A prototype circuit design has been developed and tested within the laboratory using two common radio systems: EFJohnson and Motorola. The preliminary results have shown successful operation as a system gateway between the two radio systems with good performance regarding audio signal latency and minimizing the push-to-talk signal generation delay.
