[ForSale-Swap] pin-out needed

[William J. Wickstrom]

Does anyone have the pin-out and/or schematics for the Icom UT-34 and UT-40
CTCSS modules? I am trying to substitute the UT-40 for the UT-34 in an
IC-970H, and I’ve been told (here) that the two modules use the same
components and differ only in connections. Why do I want to do this? I CAN
get the UT-40s, but NO ONE seems to have any UT-34s (two required for my
use). As I’ve indicated before, I want to retain the functionality of the
factory (Icom) modules i.e., tone programmability via the radio’s menu
system (no dip switches), so no “use a comm.-spec board” advice, please.
Any help?
