Over the past month, the FOT has noticed delays in commanding during the precalibration phase with the DSN station. During realtime, there has been no impact to commanding or telemetry. Coordinated with JPL Comm and IP NOCC to test command system and determine the nature of the observed delays in sending TEST blocks and NO_OP commands. The results of the test were indeterminate. Possible cause may have to do with ISIS. IP NOCC is continuing investigation. ========================================================================== Michael J.
