Thanks Mike, The station is 1420 AM.
Nothing else was changed besides the duplexer. The AM station audio is audible during the entire time the repeater transmitter is transmitting, even during the hang time. It is a much lower level compared to the repeated audio and it is perfectly clear. I could hear everything Rush Limbaugh was saying. Thanks for your help.
