Roger,

I have both 2800s Yasesu & Orion. Both are excellent rotators, but with large differences in capabilities and that shows in the price. However, if you ever need to dig into the yaesu controller, your curses towards the designers will be without limit. Truly mickey mouse, it seems three different engineers couldn't agree on how to interconnect three pcbs so there are random soldered wires, connectors, and jumpers between the boards. Then the factory schematic is scrambled eggs. There are redo's that have been drawn that make logical layout sense. I replaced the pointer drive belt, actually an o-ring, so if you need one, I have 90 left over after I gave away some for others to repair their rotted one. The pointer gear train is another "interesting" design choice.

I had wondered about the Yaesu rotator. I currently have a PST-61 to go back on the 45G and have a modified Ham IV for the LM470, but a nearby kam has the Orion in a 90' crank-up. If the Orion will fit the LM470, I may go that way. I'm working on the rerod cage for the base at present. I have to get help to lift any of the heavy stuff, or to hold things in place so it's kinda slow going.

OTOH, either with a Green Heron controller is fine, but I don't think you can buy the yaesu w/o the yaesu controller. A used yaesu rotator plus new Green Heron is another way to go. The clean/grease/replace balls for the yaesu is no big deal.

My Orion was a very tight fit in the HDX589, and the yaesu went easily into the other 589.
