Re: G5500 change voltage supply
I just arrived in Europe with a G5500 and was successfully able to convert the controller to 220v simply by moving the wire connected to pin 2 on the KT-30 transformer to pin 3. That's all it takes. If EA4CYG's wire is on pin 3, I would guess that someone has already converted it to 220v operation (perhaps without changing the plug to a European connector?).
To be sure that you connect to the correct pin, measure the resistance with an ohm meter between pins 0 and 2 and then 0 and 3. The resistance between 0 and 3 should be significantly more (almost double) the resistance between 0 and 2.

PS - I am now QRV from OM land on HF but not yet on the sats, due to some antenna problems.

But obviously the KT-30 must be a different transformer.

Here is the mod to change Yaesu rotors to 220v: http://www.hamcity.com/store/pc/catalog/pdf/220vconversion.pdf
But perhaps yours has a different transformer if it
uses
pin 3 for 117v. In the mod, pins 0 and 3 are for 220v.

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
