[TenTec] Orion FSK/CW/PTT interfacing

[Richard Detweiler]

Connect the CW Key to the 1/4" keyer jack on the back,

Turn the internal keyer off on the radio

I think the Tip will work for a straight key

If your interface will close the PTT during transmit, then the PTT line will 
have to be disconnected when in CW.

Hopefully there will be a fix for this in the future.
