Hi, I have been cw-ing since August 1. Mostly I have come up to speed (now copying about 12 wpm fairly comfortably, thanks to the many fine and patient cw ops out there) and encountered few things that I didn't understand. However, last night I was calling CQ on 10.112 (yes, I listened first for a while and called qrl?, too) and someone answered back, we exchanged rst, name, qth, etc then it was 73. I called CQ again and the same Op asked me to leave the frequency, which I did. Being a newbie I wondered if there was something I didn't know about (emergency channel? contest? etc) so I didn't ask questions. I wouldn't want to stay where I'm unwanted, anyway. Does anyone understand what situation I may have encountered here, for my future reference? Thank you. 73 Brady kd8zm PS: By the way, being new to this I have to say I am incredibly impressed with the encouragement and supportive nature of the more experienced CW ops out there. I don't think I have ever experienced a more passionate and encouraging group of people in my life, and that has been true on 30, 20, 40, and 17 meters (can't work the other bands very much right now due to conditions).
