One of the most pleasant sounds to be heard is the fist of W6BNB when he is using his cootie. That beats any keyer or computer that I have heard. I personally use a cootie (light years away from BNB's class), a Brown Bros. BTL-A, and a computer keyerboard program that I have written to drive my Jupiter. The cootie is by far the most fun. 73, Bill W6EET
