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.
