Sept 24:
Five sites had bad/missinig/no-serial-cable sonics:
A6 - missing sonic: no change
A12 - bad sonic: replaced S/N 1123 with S/N 0855
A17 - bad sonic: seems to have fixed itself for the moment, no action taken
A19 - missing sonic: installed S/N 0178
M, serial port 12: missing cable: installed new cable
Kurt is taking 1123 back to Boulder for Chris to test and likely ship to Campbell
Thus we need only one good sonic to install at A6
