Yes...48kHz....have run it without JT65HF too. You know the one thing I didn't try was a reboot....and avoid JT65HF for starters
He's on Windows 7 64-bit with a Signalink.

JT65HF decoding like a champ...WSJT-X is, at best, sporadic but goes for many minutes without decoding anything.

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.
