[Elecraft] K3 -> Very Early Acom 2000A

[Chuck, AE4CW]

In addition to a coax connection, the simplest approach is to hook up a key line from the Key Out on the K3 to the Key In on the Acom 2000A.  Then, simply use a single "dit" (enable SSB+CW in the CW WGHT menu) to cause the amp to auto-tune on your current frequency.  You can also issue a short vocal sound, and the amp will auto-tune.  There are a few software packages that can listen to the K3 CAT frequency changes and send them to the amp, but I think they are more trouble than they are worth; it also requires a "special" serial cable.  You should also set your K3 tune power to 15 watts which is what the 2000A expect if you wish to set a customize tuning solution for a particular band segment. 

That's all you need to be up and running.

P.S. The new 2000A Remote Control Unit can connect directly to the K3 to listen for frequency changes and automatically retune the amp for the new band segment (no SW needed).
