Good suggestions guys, but I don't have any battery chargers, batterys or
converters on the boat.
Just plain old 120v wiring.
I have walked the marina and the noise on my portable radio gets loud
when I hold the radio close to each power pedastal.

I have a boat at a marina,I cannot receive any AM radio using Marina
power.
The audio is one continuous buzz across the dial.
A battery operated radio is ok
FM reception is ok.
I took a scope down and looked at the A.C. waveform, the signal has no
visable noise riding on it, however the wave peaks are flatened. It is not
hard
clipped, it just doesn't have a nice round peaks.
I'm looking for suggestions on how to filter the AC so my
radio will pick up AM.

Thanks
Mike
