[Elecraft] Help: K3 - 2 Mic (VFOA and VFOB) 2 Computers N1MM

[Don Wilhelm]

  Jim,

Because an RS-232 serial connection is point to point, you cannot 
connect 2 computers to the K3.  Yes, SteppIR and a few other devices can 
use a "Y" cable on an RS-232 because they only "listen in" on the serial 
data, they never transmit data.

So that is the first obstacle that you will have to overcome.  Once you 
have accomplished that feat, the other parts should come easier.

73,
