Interesting comments. I have a number of modified and one pure sine wave
inverter aboard. I'll run a number RF noise tests this weekend when we
get back aboard. May be the reason I still get a bit of noise at 14 MHz.
By the way the pure sine wave unit is the only way to power a computer
and speaker system if you plan on attaching a separate sound system to
it... It totally eliminates the hum that comes with using a modified
inverter.
