stopping there, but it's fine for starting. I haven't moved forward since I'm barely using my tech license and have too many hobbies anyway. :)
I'm really pretty interested in learning CW, but haven't been able to dedicate time to it yet. I'm not even quite certain how to pick any up. Most of the time I go looking, I don't hear anything (I've only got 2m/6m/70cm equipment, though).
