[sbe-eas] EAN Test - a real disaster!

[Bob Reite]

The EAS protocol REQUIRES a time stamp, so one will be there.  If there 
are reception problems killing the time stamp, the header will be 
rejected by the decoder. That's why headers are sent three times and the 
decoder picks the two out of the three that match, if conditions do not 
allow perfect reception of all three headers.
