Emory, Check out: http://nk7z.net/adding-external-keypad-k3/ This is a short how to to add a 64 key keypad to the K3/P3, and fire off macros to it via that keypad. You preload the Pr with Macros, and then use the external keypad to fire them off to the radio/panadaptor. 73s and thanks, Dave NK7Z http://www.nk7z.net
