Alright, I'm making the plunge onto CW. I just unwrapped a Vibroplex Code Warrior Junior, which I will plug into the front panel of my Yaesu FT-991A. Now what? There are a lot of menu items associated with CW, and other than accepting the defaults, I'm not sure what menus to adjust to what values, or why. I understand there might be some sort of practice mode, short of putting it at five watts and hanging a dummy load on the rig?? I don't mind reading a reference; which one? I don't mind getting vector from an Elmer; who has the same or similar gear? I don't wish to be carried, just pointed in the right direction. Please assist, please advise.
