[AMRadio] Modified sine wave to sine wave

[rbethman]

Yes sir! That is why it is near impossible to clean up the output.

Each of those steps creates spurs, aka noise/RF hash.

I never use one except for things such as fans.  I'd never use one to 
feed any radio.

I have a Coleman inverter, DC to AC.  Looks the same on the output.  I 
can even hear a whine when it runs.
