[TenTec] Jupiter/Centurion hook up

[Paul DeWitte]

I am trying to hook up Peg's Jupiter to my Centurion amp.It is connected 
like the book shows.

I have the keying loop turned on. It will key the rig if the amp is turned 
off, but will not key the rig if the amp is turned on. It will not key the 
rig either in standby or operate when it is turned on. Turn the amp off and 
it will key the rig.

When the amp is turned on in operate, it will key the amp, but the amp does 
not key the rig. The key is plugged into the Jupiter.

Have I missed something? Maybe a bad patch cord? But if that is so then why 
does it work with the amp turned off?

Thanks for any replies.
