Hi Mike,

have you checked that the audio input device default sample rate is 48kHz ? Also using the same CODEC for JT65HF and WSJT-X at the same time may cause audio issues since they request different sample rates. Later versions of Windows manage this better than earlier ones, post Vista is best if this is done.

The frequency spreading on each symbol looks like digital distortion to me, either poor sample rate conversion or maybe DSP processing in the rig but the latter would not explain JT65HF decoding this data.
