This appears to be PSK63.   The trace has all the shape attributes of a PSK signal.   It’s apparently twice as wide as what I assume are PSK31 signals on the waterfall.

If the op was over-driving the signal or had something else going on that distorted his signal’s tones, your software may not have been able to decode it.
