All,

I have an old Yaesu G-500A elevation rotator mated to a Yaesu G-800SDX and would like to use computer controll for both. They each have their own controller, but they do not have buit-in computer controll boards.

Idiom ( http://www.idiompress.com/rotorcard.html ) makes a board for the G-800SDX, but I can't find anything for the G-500A.

What would be the best inteface / boads to use with this set-up? The Yaesu GS-232 interface is a bit pricy and was wondering about an alternative. I use NOVA software for tracking.

Thanks,

Tony -K2MO

Hi Tony K2MO

The G-500A like the KR-500 elevation rotators have only UP and DOWN manual switches and do not have relays into the controlbox to use it through computer control.

I did the modification inside a KR-500 controller using basically the same circuit of the G-5400

In a separate email I have sent to you the schematic diagram of it.

Be cautious with Idiom Press. I ordered one of their controllers advertised as "assembled and tested" a couple of months agoo. What I received was assembled MINUS the controller chip. Not sure how it was tested, if at all. I have made many requests for the missing part but nothing has been delivered in the 2+ months of waiting. Check out the complaints at eHam...
