Subject: Radar Operations Center Testbed Configuration
Identifier Changes: Effective on or about September 29, 2025

On or around September 29, 2025, the Radar Operations Center
(ROC) will implement new configuration identifiers for the ROC
Testbed Radar, KCRI.  The changes in the configuration
identifiers will be reflected in the National Level II data
stream.

The current KCRI configuration identifiers are: NOP3, NOP4,
ROP3, ROP4, FOP1, DAN1, and DOP1

The new KCRI configuration identifiers are: NOK1, NOK2, NOK3,
NOK4, NOK5, ROK1, ROK2, ROK4, and ROK5

There will be a time period where the KCRI configurations will
alternate between the current and new identifiers based on the
type of test being conducted.  The new configuration identifiers
are expected to be fully implemented with RDA/RPG Build 25.0
deployment in early to mid calendar year 2027.
