Check out FISTS, a group dedicated to code. They have several calling frequencies listed on their web site (www.fists.org
) and some clubs run slow-speed code nets just for the purpose of helping out new hams.
My club runs one on Wednesday nights, 7:00 Central time, at 7.138. The first Wednesday of the month there is no net due to our regular club meeting. More info on the web site:http://www.qsl.net/mac/
