The asterisk computer is powered by a local AC outlet and the DC supply shares the same AC circuit.  The AC and DC grounds are bonded.  The DC supply also floats about 650 amp hours of battery back up.  

Even with all the batteries, I never had any luck using a inverter or a UPS tied to the DC buss.  I thought it would be nice to power the windows based echo link computer from a computer grade UPS (or inverter) that uses the main DC supply with the batteries.  But it introduces to much noise into the system that seems to only shows up on the UHF machines.  So I have to have battery back up for the PC's separate of the system.  Has anyone ever tried a "Car Computer" case that is designed to run off of 12 volts DC?  

I should have some time Wednesday night to try all of the suggestions, Thanks again.  I will keep everyone posted.
