I know that! I'm trying to get a copy of the "board" lay out,
schematic and hook up. As I said, this board has "A" transistor
difference than the TS 32


The site I gave did have a board layout and hookup. Just how different
from that board layout is your slightly older unit? One or two IC's should
not make much difference from the overall layout already cited. This is a
simple CTCSS encoder. It only has three connections to it. There are only
three pins on that board, one for Ground, one for A+, and the output
pin. There will probably be a diode right off the A+ pin, the ground pin
should be obvious if you look at the underlying traces, and the output pin
will be off notabily separate from the A+ and ground pins and should be
capacitively fed.
