I got the configuration file of EI2MLD just now,


[snip]
UIDigiCall             =       WIDE1-1, WIDE7-7, WIDE6-6, WIDE5-5,  
WIDE4-1, WIDE5-2, WIDE6-3, WIDE7-4

//----------------------------------------------------------------------

//----------------------------------------------------------------------

// UI Flood Call (up to 6 characters)
// Default (WIDE)
// UIFlood [call]

UIFloodCall            =       SE

//----------------------------------------------------------------------

//----------------------------------------------------------------------

// UI Trace Call (up to 6 characters)
// Default (TRACE)
// UITrace [call]

UITraceCall            =       WIDE


// Duplicate Packet Suppression Interval second (default 28)
// range 0-180 seconds
// UICheck [n]

DuplicateSuppression   =       28
[snip]

So I'm not sure why it shouldn't have caught the dupe, unless of  
course as Scott pointed out, that the last character of the packet  
had changed (going through javAPRSSrvr) for some reason. Its not been  
rebooted or anything and it seems to be performing dupe suppression  
fine at the moment

Regards
John
