Hi Folks, Using the combination of WriteLog with ARRL Field Day and FT8 requires you to upgrade: 1. If you really must run wsjtx-2.0 then you need the most recent update to WriteLog's UDP listener. The direct link to the download kit is: http://writelog.com/Downloads/WriteLogUdpListenerV09.zip 2. We recommend DigiRite instead. A new version is posted that properly supports Field Day http://writelog.com/Downloads/DigiRiteInstall-1.1.08.msi If you have any questions, let us know! Thanks, Steve N9OH & Wayne W5XD
