[sbe-eas] EAN

[Richard Rudman]

A prime concern about continued use of the LP model is the additional  
CAP "payload" that an LP would have to relay vs. "classic" EAS.

When (rather than if in my personal opinion) mandatory state/local is  
part of a revised Part 11, LP stations would have to endure  
broadcasting the extended "payload" of a CAP message.

This, according to vendors I have talked to could result in 30-45  
seconds of digital non-language transmission.

There might be a way around this by having what relay stations need to  
survive broadcast a decoded CAP message.

Obviously, that would defeat a goal of getting CAP messages to all  
stations as quickly as possible.

This and other issues need to be discussed throughly by concerned  
stakeholders in this and other forums.
