I would like to wire up a remote keypad to access the built-in
keyer. I purchased a 12 button membrane switch which uses a 3 X 4
matrix. I wanted a switch with 12 seperate buttons, but have been
unable to find one. My question is; can I use the matrix switch by
hooking it up to a set of AND gates to do the switching, and if so, can
anyone supply me with a "cook book" procedure to do this (in other words
I can wire it up, but I need a FULL schematic).
Thanks in advance for any help 73 Steve N2QLQ
