Was operating smoothly when suddenly the auto-sequencer started sending "KD9EFO K5JAZ R EM32" in lieu of the signal report. I deleted then reinstalled v1.8.0 but R EM32 remained in Tx 3. I started v1.7.1-1870 and problem remained. The problem must lie in a configuration file in the Appdata/Local/WSJT-X/ directory, but I have been unsuccessful in locating it. Any help greatly appreciated.
