[Elecraft] K3 Macro to control KEY OUT

[Don Wilhelm]

  Vic,

I am going to lobby for an "Amp Inhibit" input in every amplifier that 
will accept exactly what your external relay driven by DIGOUT1 signal is 
doing. :-)

IT does not have to place the amp in standby, it just opens the Key In 
line, and would be easily be done inside the amplifier.  When the signal 
is present, the amp ignores the Key In line.
