I have purchased a G5500. The control box have a 117Vac label in the real panel. I opened it and a wire is connected through the fuse to the terminal number 3 of the KT-30 transformer and the other wire through the main switch to the terminal number 1 of the KT-30 transformer.
I am wondering how I should connect it to work with 220Vac in Europe.
Thanks in advance. ea4cyq@amsat.org

Hi Juan Antonio, EA4CYQ
Happy to hear from you again ! How many wires comes out from the primary winding of the KT-30 transformer ?
If the primay winding of KT-30 transformer has only two wires the number 3 and the number 1 then it has been winded to work only with 117 Vac and in this case you need an external autotransformer 220/117 to supply the control box.
On the reversed side if the primary winding of the KT-30 transformer has four wires it means that the primary has been made with two separate windings of 117 Vac each so that is you connect two windings in parallel you can supply it with 117 Vac and if you connect two windings in series with the correct phase relationship you can supply it with 220 Vac

I have both rotor manuals for G5500 -& G5400/5600 Yaesu units. The schematics for both DO NOT show any wiring changes for the transformers to work on 117VAC or 220VAC. The manuals do say that there are "Different" transformers for 117 and 220 VAC use. It even states that they should be returned to have the proper transformer installed if incorrect- This means that there may not be a universal transformer installed and only wiring changes to correct the AC input. Check with Yaesu for the correct transformer part number required. Good Luck, Dee, NB2F
