@Shufei This reminds me of a fun story.
Once upon a time it was illegal for US amateur stations to make contact with their Cuban counterparts.
One day a US station hears a Cuban station down on HF (I forget what band). US station says to his buddy "It's a real shame we're not allowed to talk to Cuba because I'm hearing <callsign> 59 here."
Cuban station then says to nobody in particular "It's a shame we cannot talk to the US because I hear <callsign> 59 here."
No regs were broken that day.
@nivex Hahaha, that’s lovely, and about the way it goes. Along with things like, “It’s a shame people sometimes call without callsign on 6666khz using a short path beam directed 310°“, no doubt.
