Hi Jed,

You might give a bit more detail about how your system is configured. 
Sound driver, and settings etc. Does CTCSS tones come into the picture?
More clues as to what HUM actually means. Saying they all produce a nice 
little hum??? ... is a bit vague.
Are you talking hum when Nodes receive signals via RF or VOIP? Do you 
hear the hum while your system is transmitting and you are monitoring 
with different of radios?

The more details you provide the better help you will receive.
