[Elecraft] Feed PTT thrue coax for DB6NT Transceiver

[Don Wilhelm]

Martin,

I would strongly suggest using the 8R signal instead - when inverted it 
is the same as the signal from the KPA100 ext amp keying interface or 
the Amp Keying interface for the base K2 that is offered by Tom N0SS.

8R can be set to a delay in the K2 menu and is present about 15ms prior 
to the onset of RF, 8T cannot be manipulated by the menu parameters.

The amp keying interface grounds when active, but you could drive a 
small (fast) relay that will in turn provide your required voltage.

73,
Don W3FPR
