[Dxbase] LoTW Question

[TNeill1648 at aol.com]

I upgraded from DXB 2004 to DXB 2005 in March and have not submitted any LoTW 
updates until today.

For some reason, when I run the TQSL to convert the DXBase 200d adif file, I 
get an error message on all of my USB contacts.  Unable to identify mode.

When I attempt to upload the file to LoTW the error message I get is...."No 
recognized signing specification in tContact Record".

Any suggestions would be appreciated.  I uploaded over 25,000 contacts in DXB 
2004 without problems.  

Thanks. Tom K4XG
