Next message: Roger Rippy: "Re: lv-ab: Ground plane"
If you are ever going to have a short-wave radio on board -- receiver or
transmitter -- then it would be better, I think, to go with a pure sine
wave. The "sharp edges" of the "modified" sine wave create harmonics
(multiples of the fundamental power frequency) which may interfere with
short wave reception, occurring as they do every 50 Hz or 60 Hz
(depending on whether your inverter puts out 50 Hz or 60 Hz "modified
sine wave").
There are plenty of other sources of EMI on a boat already (fluorescent
lights, wind generators, etc.). Don't add yet another noise source to
interfere with your (or indeed, your neighbours') reception of shortwave
signals.
