[Yaesu] FT1000 MP Keyer Control

[Steve Meltz]

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
