Ran every head through EC100 number 1817 using ECMon.  Found the following:

I have a call in to Campbell.  I'm hoping that going back a rev (from 100.07) on EC100 firmware will fix 1001–1010.  Heads 2050/2051 may have to be sent back (sad).

    While talking/testing to Larry Jacobson, everything was perfect!  remember back-door of "TERM", then "$" toggle to display raw stuff].  Moved back to staging area and everything was spiky.  By tying head/EC100/DSM all to earth (power plug ground), I can make spikes go away.  Thus, careful grounding is needed, though shouldn't be hard to achieve in the field.  We'll remember to bring grounding materials (straps/clamps/etc.)

    Also, later in the day, Larry sent code with the S/N 2051 calibrations that I <re>loaded into the head.   Now 2051 works just fine.
