[Elecraft] Best way to connect K3, P3, Steppir, Acom 600s and PC

[Don Wilhelm]

Alan,

Another answer along with a bit more data and a caution - IF the amp is 
capable of listening on the RS-232 connection for band information, add 
another "Y" cable between your current "Y" cable and the PC and the amp 
should be able to use that data.

Caution, if the amp uses full RS-232 communication (both send and 
listen), that will interfere with your current setup.  BUT if the amp 
only 'listens' to the information on the RS-232 interface, all will work 
well.

In other words, an RS-232 connection can have only one set of drivers. 
Multiple devices can 'listen in' to the traffic on the receive line with 
no problem.
