REMINDER  ,
Due to the failure of STX-3 on NOAA-17 SOCC has had to make configuration changes to transmitters used for HRPT and playbacks. NOAA-18 and NOAA-17 are affected by these changes. These changes go into effect on 26 Feb 08 (JD057) on the revs (orbits) and UTC times noted in the table. This configuration will remain indefinitely. 
Constellation transmitter changes are provided below.
