Hello Jason, I agree with Dwayne, except that I see that you are running 100 watts on 2 meters and plan to run 30 watts on 70cm. That power level would probably burn up one of the ham quality diplexers in time. You are better off with a commercial unit, such as the TX/RX one Dwayne recommended. Also keep in mind that the dual band antenna that you use will have to hold up combined power.
