[GreenKeys] Dovetron TU question - keying a transmitter

[ken Schwieker]

In the KOS-100 instructions last page it appears to describe what you 
are looking for. If that board
is not present, it seems like there should be a location in the 
Dovetron tx circuit to place an opto-coupler
to sense a key press. The opto-coupler would be connected to a user 
built adjustable hold timer
circuit to generate the tx closure. If that wasn't feasible then a 
circuit across the keyboard to sense
the open circuit voltage connected to the previously mentioned timer 
circuit should also work.

Good luck,
Ken S
