Nope. The key inputs of both amps are buffered.  Partial schematic of Titan is here. http://k9yc.com/TitanKeyingLogic.pdf K4XU once told me that it was his initials on the published schematics, and I think he later worked for Alpha.  For operation with most rigs, the PTT position of the PTT/K

Not a great choice. SWR gets increasing nasty above 15M because the construction uses chassis as signal return rather than carrying it on the circuit board. It's a two-sided board, but the "ground" layer is broken under the traces that carry the RF, so return current can't flow on that layer. I
