this may or may not affect you.

If you need to import the WSJT log to N1MM (or something else...)
be aware there is a bug in WSJT 2.2 when the program CREATES a new ADIF file.

The error is in the 1st line of the file, and is very easy to fix in notepad (or other basic text editor.. -  not wordpad... or office or word processor type program...)

the end of the header line will be <eh> if the bug has affected you.  It must be <eoh> (note the simple addition of lower case o to fix...)
add this 'o' if it is missing and save the file.
then the file is fixed, until WSJT creates a new file.
(once the file has the correct header, WSJT does NOT break it again. the issue is ONLY at file creation.)
