[Elecraft] N6XI NAQP RTTY July, 2007 with K3

[Tom Hammond]

Hi Jeff:

IF you do, how will you then tell the radio specific serial cable pin 
to look at for CW keying/RTTY keying/PTT/etc?

If you place them, as Rick and others do, then you can create 
mode-specific interfaces for your software.

IF you put them inside the rig, then THAT particular pin will ALWAYS 
be dedicated to that specific task, even though the next software 
might want to use a different pin to do the same task.

I'd much prefer to have this sort of thing external to the rig and 
just use them to KEY the dedicated input on the rig.

73,
