Not seeing noise here either (or data from the mote, for that matter).
-----------------------
Interlude: look at snapshots of data from other projects:
TREX: Don't see 2Hz noise for a case when V~0.6V at night (though white digitizing noise is obvious). Noise level is much lower than seen in CWEX (so CWEX noise would show up).
dpar(start="2006 mar 30 04:00",lenmin=30)
iod = prep("kh2oV.30m#3")
PCAPS: Also no 2Hz noise for a case with V~0.6V at night. Similar comments as above.
