The frequency is generally no more and often a lot less important than the
voltage. Power companies maintain a highly accurate frequency for
timekeeping and even raise or lower it slightly to keep the clocks on time.
The generator frequency will not be accurate enough for time keeping unless
it has a very sophisticated governor. For emergency use it is general
practice to set the no-load voltage and frequency on the high side and let
the governor and voltage regulator do their best at maintaing a satisfactory
output as the load varies.

I've finished building my ChangFa generator project and had it producing
power today.

I borrowed a friends "Kill-A-Watt" meter to monitor the output voltage and
freq of my genset. I adjusted the engine speed to indicate 60hz and the
voltage was at 127V. I used the meter to measure the house voltage and it
measured 120V, with power provided by the power company.

The ST-10 style genhead can have the output voltage adjusted by
installing a 5 ohm, 200W rheostat. Where does one find such a beast?
Or is 127V an acceptable voltage?

Thanks
