T&T: 60-cycle hum in VHF audio

[Truelove39 at aol.com]

Our Xantrex inverter/charger creates a 60-cycle hum in both VHF radios (not  
inverting). The amplitude of the hum varies with the voltage in "float"  mode. 
I can't find any commercial solutions online. The grounding/bonding  systems 
are in good order, and we have an isolation transformer.  
Suggestions/solutions appreciated!
