Hi Ian, K8MM

In a separate email I have sent to you my schematic diagrams and my modifications to add relays into the G-400 and G-500 rotators as well how to pick up the ground for the position pots.

It works very well for me.

Have fun

Hello everyone

Is anyone using a LVB tracker interface with a Yaesu G-450A Az and G-500A elev rotators? I know I have to pick up 12V somewhere in one of the control boxes to run the LVB interface. I know that I have to install some relays between the LVB interface and the control boxes that will do the heavy current switching for the motors. My question is how did you pick up the ground for the position pots when there are two different control boxes. I wondering if there could be a problem tying the position pot reference grounds in both boxes together?

I haven't really been on the birds much after I went to FP back in 2005 and activated GN17. I had to disassemble the station to take it there and then we moved 5 months later, since then my satellite station has been mothballed.
