I have been playing around with the digital coded squelch function on my DJ-580. When I go to try the DCS wild card function on page 37 of the manual my radio allows me to do steps 1-3 in the manual but it will not allow me to do steps 4-6 for some reason. I would like to know what I am doing wrong and how to get those steps to work for me. Thanks. 73's. Eddie KD4VYK
