Off Topic: how would you get a signal into a radio IC without broadcasting?

I'm using my stm32f446 nucleo to build a weather band radio with SAME decoder.  If the weather is good, the only emergency alert broadcast is the required weekly test.  Debugging my code when I have only one opportunity to receive a message per week, is slow going.  I do have a .wav file of an emergency alert broadcast, and would like to somehow get it into the antenna pin of an si4707 chip, without actually broadcasting it.  Perhaps someone here knows how to go from a .wav file on a computer to the antenna pin of a radio IC.  The chip manufacturer's forum is rather inactive.  Any ideas?
