[CQ-Contest] Yaesu rotor conversion to 220 volts

[Pete Smith]

I agree with Dale about the Yaesu techs - one named Jerry, whose last 
name I've forgotten (Barber?), is particularly familiar with rotators.

That said, I have looked at the schematic diagram for the 800SA, and the 
power transformer doesn't have any switchable taps, nor are there any 
clever switching power supply devices to enable a wide range of input 
voltages.  The manual cautions you to be sure to use the AC voltage 
shown on the sticker on the back, and makes no reference to changing 
input voltages.
