Topic:
Change in Transmission Frequencies for VHF Real-Time Antenna Transmitter (VTX) users

Date/Time(UTC) Message Issued:
18 June 2009, 2000 UTC

Satellite(s) Involved:
NOAA-18, NOAA-19

Instrument(s) Involved:
AVHRR

Product(s) Involved/Affected:
APT data

Date/Time(UTC) of Initial Implementation:
23 June 2009, Time 1824Z

Details/Specifics of Change

On 23 June 2009, NOAA will implement the following VTX configuration changes:

NOAA-19's operational VTX frequency will be switched to 137.1 MHz (from VTX2 to VTX1). The change will occur during rev 1936 between the first command time of 1824Z and the last command time of 1838Z.

NOAA-18's operational VTX frequency will be switched to 137.9125 MHz (from VTX1 to VTX2). The change will occur during rev 21088 between the first command time of 1852Z and the last command time of 1904Z.

This change will not impact APT data on any other NOAA satellite since both of the NOAA-18 and NOAA-19 VTX frequencies are different than the rest of the constellation.
