"collabo" isn't in the standard Spanish dictionary. But, my dictionary is only two and a half inches thick and doesn't have much slang. So what does "collabo" mean?

It can't come from "collaborator" as that word is "colaborador."

Collaboratore. Che è italiano, non spagnolo.

Ah, Italian.
How could I guess from your call sign?

It’s French slang for, “collaborator.”
