[TenTec] Argo V amp keying

[Mike Bryce]

bob,

isn't that assuming that you're using an external keyer?

I designed a small circuit board that will go inside the argo v and will provide powermosfet output.

the input is optical coupled to the rig.

the pcb about the size of a quarter.

I'll look around the shack and see if I have a few left.

A man with one clock knows what time it is. A man with two clocks is never sure.

It works this way for situations where one does not have QSK keying ability when using the Centurion amp and some other radio that does not have QSK capability.  The key is connected to the amp {not the radio}  and the keying circuit in the amp then keys the radio upon key closure.  The AUX connector on the back of the ARGO V does have access to the PTT for that reason.
