WSJT Merge Program Version 3.0, Written by Russ K2TXB
For those who are not familiar with this program, the file "call3.txt" is supplied with the WSJT program and is used for looking up the call that you enter in the WSJT screen. The purpose of WsjtMerge is to allow you to merge other copies of the call3.txt (from other users) with your existing file.  This way you will not lose your existing data in case it is not duplicated in the new file.  It can also convert some older format calls text files to the Calls3 format.

Download the zip file to get both the program and the documentation:

Please report any problems you may have with WsjtMerge to me at
