What do you have set as the keying method in DM-780? I use it extensively

Scott,
The K3 KEYOUT can handle up to 200 volts as long as it is a positive

Sorry, I still don't think it will work reliably with the ICOM unpowered, if it

If the Icom used an amp key line from an NPN transistor with an open

This sounds like your K3 is configured for DTR keying. Go to the CONFIG menu

I'm not sure I'm understanding your problem. Are you talking about

Shortening of characters in QSK is a common issue in many transceivers
