[Elecraft] Adding an SPE amplifier

[Igor Sokolov]

I have exactly the same setup with Expert 1K-FA, K3 and P3 and have been 
using it for the last 5 years. I actually have a pair of K3s connected to 
1K-FA simultaneously. It is pretty easy to connect SPE amp to your system. 
You need to make Y splitter for RS 232 port of K3. One leg of Y goes to P3, 
another goes to one of the DB15 connectors of the amp. The details are in 
the SPE manual that you can download prior to your purchase. This amp 
actually got 3 x RS232  ports. 2 ports are on DB15 connectors (these are 
used for CAT connection of 2 transceivers, PTT, ALC etc) and one port on DB9 
connector used for remoting the amplifier where you can duplicate all the 
buttons and meters on the computer screen with the help of a software SPE 
supplies with the amp.

The SPE Expert Amp needs a separate connector to the port. It does not do 
CAT control, but rather connects to a separate program to duplicate the 
control functions on the front of the amp. For CAT control it connects to 
the DB-15 Acc connector.

I have a K3 and a P3 which are 'daisy-chained' to the computer in the
normal manner. I am thinking of getting an SPE amplifier and am
wondering how to connect its RS-232 port into the mix. Is there some
kind of splitter or router that will add it in? Or some other method?

Thanks in advance.
