WSJT-X 1.3 r3673
Windows 7 Pro SP1 64-bit
I've been unhappy with the various flavors of JT65-HF, so I downloaded and fired up WSJT-X 1.3 last night.
It's working really well, but I tried to send a "Free msg" acknowledging my first SV on 12 meters, and got gibberish.
I wanted to say "TNX SV/12M 73" but instead it said "BX3RQN 12M 73"
