Yaesu has revamped their rotator product line so that they all share a common computer interface that is now optional rather than built in to the standard control box. This interface (GS-232) is the same as that used on the G-800SDX and isn't compatible with the KCT board according to the local Yaesu service people.
I just got through modifying my G-800S to add a KCT interface like the old G-5400. However, it definitely voids the warranty.

Subject: [amsat-bb] Which Rotator??
After a very long process, I can see the end of my new (and first)
satellite station setup.
Here's my situation. I indend to have a mostly computer automated station,
with satellite tracking, doppler correction and automated message
processing. I also indend to work the analog birds when I am home.
I had originally planned on a Yeasu G-5400 rotator, connected to a Kansas
City Tracker/Tuner running some yet undertermined software, probably wisp
and nova for windows.
I now have a problem. Yaesu seems to have discontinued the 5400, and
replaced it with a 5500. Is this the same unit relabled? If not, will it
still function via computer control with the KCT/T? Is it as "good" as the
I ask now, becasue I'm heading to dayton, and I'm sure there will be stock
of both units. I plan on having a long lasting installation so I want the
most up to date model, but if there are disadvantages, I need to know about
them to make an informed decision..
thanks for your time
