Because it doesn’t know the words! Or, it could be that you are suffering from one of several technical causes of hum in transmitter circuits…
According to the folks at North Country Radio, there are several causes to consider.
These causes include:
• Power supply hum due to poor DC supply filtering
• AC hum pickup in the transmitter audio due to poor shielding
• Ground loops
• RF induced hum modulation on the transmitted signal
What’s the cure? Here are several links to technical articles dealing with hum reduction in audio and RF circuits:
