E25 over Polish Radio

E25 appeared over Polish Radio with a massive S9+10 while PR alone was only S5-S7. Here's a clip of the transmission, recorded at 1347z using the Icom using USB mode to avoid QRM. Note the slight echo. The message was:

g14
4121 4041 9811 5592 8876 1949 8148 7233 0693 0321
1043 9173 6024 9811

They QRT at 1354z.

I wonder: Should I QSL Polish Radio asking about the "strange man" disturbing their English Program? Or more precisely their Listener's Letters program? Yes they do have one, every Sunday!
