HB9GVW / sorry wrong reference

Today I activated SM/OG-001. For some reason, I managed to spot myself on DM/BW-851 until another activator made me aware of this.
Sorry to all chasers! Please correct your answers.

To the activator that alerted me to my mistake: Sorry & many thanks for pointing it out. Unfortunately at this point in time, I got massive QRM from a frequency just above and I didn’t get your callsign.
