[AMSAT-BB] Satellite on 427.025 sending callsign OM9XPA

I was tuning around on 70cm this morning looking for satellites and found a signal on 437.025MHz sending callsign OM9XPA plus a short burst of digital signal. Time was around 2021-06-1230utc.

I thought it might be GRBAlpha but that one was not in range at the time.

Can't put my finger on which one it might be.

Ideas?
