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

Subject: [amsat-bb] G5500 change voltage supply

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 at amsat.org
