Subject:
PVC/SKYRAD/M1 - Instrument noise
DataStreams:pvcskyrad20sM1.a0, pvcskyrad60sM1.b1
Description:
All instruments on Skyrad exhibit intermittant erratic behavior from 10/05 through 10/23. 
Appears to have been an grounding issue with the IRT installed on Skyrad and replaced 
10/17. After the last problem period on 10/23 the problem resolved itself without operator 
involvement.

All data on Skyrad during these erratic behaviour periods are not recoverable. Bad data 
can generally be identified by screening vBatt for values outside normal operation range of 
13.3-13.6V.
