[amsat-bb] programming the TH-D72a

I am trying to program the TH-D72a for satellite operation using the Kenwood MCP-4 software.   I need some direction to enable me to transmit on one vfo and receive on the other.   I'm finding nothing on YouTube .   I know it can be done but unclear on the steps to get there.   Thanks for your help . 73 Jim K8ZZU EN82/EL96 (in the winter)
