今天收到封邮件，发自于一位年初rtty模式通到的puerto rico朋友carlos，这位老兄急切地需要任意波段的cw qso，有兴趣的朋友可以直接与carlos（wp4u）联系，e-mail：wp4u@mail.ayustar.net.
邮件原文如下：
hello lu; this is your friend carlos(wp4u) from puerto rico. i will like to know if you work cw mode. i need your country on cw. i never found or made any qso with china on cw. please let me know to make an squedule with you or with someone from your country. it is very difficult work china from puerto rico. a lot of usa and europe station call and make us very very difficult to work you. the operator from china have to say "only the caribbean area" so all the other station can stop calling and you can listen us(the caribbean). well lu thanks again and i will always remember our rtty qso. the only one i ever made with your country. congratulations!! 73' carlos(wp4u)puerto rico
