In the previous post I mentioned that I’m seeing a 91% LoTW confirmation rate when using digital modes. It’s worth mentioning that while chasing DXCC Digital I only call DX stations known to be LoTW users. This is accomplished using the built-in WSJT feature to colorize received station call signs that appear in the global user activity file. The software can be configured to download this file (see the manual under installation) or it can be done manually from time to time:
Go to https://lotw.arrl.org/lotw-user-activity.csv in a web browser, download the file, then move it to the WSJT-X log files directory. This directory can be opened by selecting File-Open log directory from the main menu.
While it’s no guarantee of an LoTW confirmation, my rate of return has improved considerably since applying this technique and it has definitely saved me time in the process.
