Re: Static on FM Radio

Not sure the details  of my charger but it's a West Marine charger and

off, and bingo! Noise begone!  But, obviously, I'm going to continue
charging my batteries.  So I can find out the details and change out to
a Linear Regulated Charger.  Another question raised by the first
person who responded to this post, is the noise via the wiring, or is
it RF output that the FM is picking up?

Most of the "Noisy" Marine Battery Chargers, use an SCR to
control the charging duty cycle.  These are notoriously noisy
as the SCR "Rings" when triggered, causing the noise. OEM's
like this system because it is CHEAP to build.  Any good
Linear Regulated Charger will be much quieter, if not silent.
If noise is your problem, spend you money on a good Linear
Regulated Charger.

I had a lot of interference with a Cristec battery charger on both FM radio
and VHF. Cured it by replacing it with a Sterling charger.

What make is yours?

I've got excessive static on my FM radio, and discovered it's my
battery charger.  Obviously,  I want to keep the charger going, but
wonder if anyone knows how to suppress that noise.

Also, my refrigerator works on my batteries, and my charger charges
them.  Is this going to decrease the battery life, to be continually
running the refrigeration on batteries, then charging the batteries to
keep up?  

thanks for any information,
