66: Sonics, Site stn2, Fri 07-Dec-2001 17:52:04 MST, sonic interruptions
I put my mitten in the sonic path for 2 seconds to see if the serializer heater
flag would change (from 256).  It didn't.  Sorry for the data interruption.


28: Sonics, Site stn2, Sun 02-Dec-2001 17:39:17 MST, bare sonic moved down
About 1/2 hour ago, I moved the sonic down to just above the T/RH crossarm
level on the bare station.  (You should be able to tell when, because I had 
to disconnect the krypton.)  The height of this sensor will have to be 
remeasured.

I also noticed that the T/RH fan went fast/slow/off -- something may be weird
with power.

24: Sonics, Site tower, Sat 01-Dec-2001 17:47:23 MST, increased sampling rate on 20m sonic
data_stats showed that the 20 meter sonic was reporting at 20hz
instead of 60.

I changed it with rserial at 17:45 MST Dec 1,
using the campbell T and Ae commands:

  rserial marigold 201
  ... hex output
  enter "T" to put it in terminal mode
  ctrl-D to get out of rserial

Run rserial in ascii mode:

  rserial -A marigold 201
  ??  display status
  Ae  set it to 60hz
  D   back in data mode
  binary gibberish
  ctrl-D
