Hi, anybody out there use CW? And especially a Iambic Keyer? I put this together to help me learn CW.
Wondering if you have any ideas on improvements (e.g. pause length or other).
I also don't know what I should have the stamp output if BOTH keys (the 'dit' key and the 'dah' key) are depressed. Any thoughts on that? Right now it simply outputs 'dit, dah, dit, dah, dit, dah...' I know that seems like a beginner, basic question, but that's where I'm at as a keyer lol! Very basic!!
