[VHFcontesting] inverters

[Zack Widup]

There was an article in one of the ham magazines within the last decade on 
how to build a 12 VDC generator using an automobile alternator and a small 
engine (such as a lawn mower engine).

It looked like something that can easily be built from "junk" parts and 
would power a small station pretty easily. Probably very clean DC output 
but maybe noisy sound-wise. I haven't built it yet but might give it a 
try. It would definitely handle my QRP-portable operations.
