I love CW. I enjoy both International Morsecode and Japanese Morsecode. As a non-native English speaker, CW chat by English language is a big challenge for me. But QRQ chat by English sounds very cool!
I read an article written by JK1OPL on the latest Japanese CQ Hamradio magaizne (May 2009 issue). In the article, he introduces Q-code "QRJ". I've never heard such Q-Code "QRJ". In the article it is explained that QRJ means "Your signal is too weak to continue QSO." something like that.
I searched "QRJ" by internet and found the site where ITU regulations are listed: Here According to this site, QRJ stands for "How many radiotelephone calls have you to book?" in question style. "I have ... radiotelephone calls to book." as answer.
