[Elecraft] K3: External Macro Launcher

[David Cole]

Hi Joe,

Thank you for taking the time to explain so thoroughly!  I now
understand the connections involved, and the options.  

I think I need the RS-232 version, and the passive splitter you
mentioned.  I have a P3, and a Computer connected, so I have no serial
ports remaining.  I could split at the back of the P3, and put the
keypad on there...

Thanks and 73's,
