Hi Roger, WA1KAT

I have used the KR-400 as a single unit for the azimuth and a
KR-500 as a single unit for the elevation since OSCAR-7 and
provided a preventional maintenance they worked very well for
many years.

I have the manuals on paper and I have modified the control box
of both adding relays and the electronics necessary to command
it with PC for the automatic traking.

In a separate email I have sent to you the electrical schematic
diagrams for the above modifications.

Tanks for the internet address of the manual.
