      The Ensemble RXTX was working fine and then quit.

      So far I have check the 12v bus -- okay
      5v bus 2.7 volts.

      Current draw in receive mode 128 ma.

      I removed the 5v regulator and checked the resistance
      of the 5v bus to ground, about 10 ohms! I suspect that
      one or more of the six chips died.

      Any suggestions on finding the problem?

      thanks,
