Below is an article that I wrote for new CW ops who want to either operate QRS or want to improve their speed. Also check the W1AW schedule on the internet. They send practice CW at 5wpm and up and the signal is very strong. http://www.arrl.org/w1aw.html
You have just passed your code test and now what? You may try listening on the bands and find that the speeds are just to fast for you to even think about trying to copy. This can get very discouraging for a new ham. Many new hams want to operate CW but often find the speeds they hear on the air to be very intimidating. You can just listen to the ARRL CW practice on the air but that gets boring after awhile. There is another option. There is a Yahoo group devoted to QRS CW. This is a great opportunity for new hams to get together with other hams who operate at the same speed and for some of you experienced CW ops to share information with the group and QRS to make contacts with these new hams. I have found the best way to enjoy CW was to make contacts with other hams. After operating QRS for a while you will notice that your speed will start to increase. The website for the group is: http://groups.yahoo.com/group/QRS-CW/
Here is a list of the unofficial QRS CW operating frequencies. These frequencies are only a guideline as a place for the group to meet and are not part of any band plan. If you hear a slow speed CQ out there then answer the call and enjoy a relaxed QSO at a slower speed.
Most QRS activity seems to be on 7.050 & 14.050.
