The TRH at 30m is acting up. Here is the data when it goes bad:

Note that the delta-Ts when it is working correctly are around 0.82 secs and when it goes
nuts are around 0.55 sec. Steve thinks it may be a PIC processor issue.

March 12, 2010, 9:15 MST arrived at tower
Plan: correct problem of spotty CNR1 data, replace TRH fan at 2 meters
rserial on port 19 showed no CNR1 data. Power cycled CNR1 by
unplugging/replugging. No data.
Switched CNR1 cable to port 5 (2 meter TRH's port). CNR1 works on that port.
Changed config to use unused port 14 as the CNR1 port. CNR1 also works
on that port.
Power on port 19 looked OK, and TRH worked on that port.
9:27 MST: new fan in 2 meter TRH.
Ned determined that the 7 meter TRH fan was noisy, so we replaced
that too.
System voltage, as measured by the DVM in the serial test box, fluctuates
from 11.8 to 13.2 volts, with a period of something like 10 seconds.
I assume that is due to the trickle charger.
At one point I saw the CNR1 data pause for about 20 seconds, and then
several records came out at once. That was after it had been running
for a while - not at startup.
Off tower at 10:30. Left site after a tour up the walkup tower and
chem seatainer.
