In amateur radio, especially CW/morse code, CQ means "looking for someone to talk to". It's an abbreviated homonym for "seek you".

If you hear "CQ CQ CQ de WB6NOA" being transmitted, it would mean the person who owns call sign WB6NOA is looking to talk to someone on this frequency.

i did know that (in the back of my brain, and watching Ellie in "Contact") but don't see how it applies here.
