[VHFcontesting] Keying Amplifier before the Transverter

[wa4kxy at bellsouth.net]

I would suggest using a sequencer.  You key the sequencer and then the sequencer keys the amplifier, transverter and finally the TS-850S in that order.  What you are proposing will probably work (I have done things like that in the past) but the sequencer is guaranteed to work.  DEMI sells one in a kit for $60 or $95 if you want it assembled.
