Good. I agree with Don -- RF feedback or excessive TXEQ are 
possibilities. How is your TXEQ set? Is anything boosted? Are the bottom 
three bands turned way down? What mic, how is it wired, how/where do you 
plug it in? Were you transmitting with the amp when you recorded the 
messages for the voice recorder?

I also agree that you should try to listen with the KX3 with its antenna 
disconnected.
