The NWS Legacy EMWIN services will terminate effective 1700Z December 2, 2019.  The individual
services include:

-EMWIN Satellite Broadcast Service (1692.7 MHz, GOES-14/15)
-EMWIN File Transfer Protocol (FTP) archive file server
-EMWIN ByteBlaster and HostMaster public Internet dissemination services at NWS Headquarters

On August 29, 2019, the NWS follow-on enterprise EMWIN (eEMWIN) services were placed into operations

following the release of a public notification issued on August 29, 2019, via Service Change Notice:

The new eEMWIN services consist of:



-eEMWIN satellite broadcast service on the NESDIS GOES-East and GOES-West HRIT/EMWIN Broadcast
(1694.1 MHz, GOES-16/17)



-eEMWIN anonymous FTP archive file server

NWS will provide more than 90 days of parallel operations of the legacy EMWIN services and the
updated eEMWIN services before terminating the legacy EMWIN services on December 2, 2019. This
overlap should provide users the opportunity to acquire, install, operate and transition to the new
HRIT/EMWIN receiving system and software, with minimal impact to current operations.
