10m - tropo?

In the last few hours, I have spotted PB0AIC several times with low(ish) Doppler at 288km.  This is far too short for Es (unless the skip is extremely short, suggesting a 2m Es opening?) so I wonder if this is pure tropo? The distance exceeds most GDX  (usually possible with aircraft reflections) out to around 200km.  I have spotted PA stations before on 10m now.
