fridge noise over radio.

Thanks Allan,
I'll go out and earth the fridge today and source a ferrite noise suppressor tomorrow.
I'll report back when dine.

Hi Allan,
I earthed the fridge and found a ferrite noise suppressor on an old lead and have fitted it.
I'll test it out in the next few days and see how it goes,
once again thank you.

sounds like electrical interference i have similar issues especially when using AM freqs in country even around metro. I get interference from transformers as I drive past. - same vehicle Prado 120 d4d however antenna usually mounted on passenger rear side window and a very directional one as well

Gets even worse when your out bush with hazard light on brakes etc with LED hi mount lights plus the ABC radio - section between meekatharra nd newman is dead spot with nothing period better off using the ipod

so should it be the antenna for the AM/FM radio that needs a suppressor or the powered auxiliaries (fridge hi mount lights etc) in the vehicle

Hi Batt's.
It's a old fridge which I have put back in the car.
I have had the fridge in the same location before with the same noise.
I have the fridge earthed to the body through a separate wire now and a ferrite filled as per Allan's advise.
It is powered by a lithium battery using a Redarc bcdc dual input charger.

If you have an inverter could you try running the fridge on 240v when driving to see if there is a difference ??

Hi mechpete.
The antennae is in the glass.
William

You can still fit another antenna

.
William, was the interference like a 'hum' or more like static as when the radio is tuned off-station?

Hi William,
Your expression "worse when the fridge cycled on" implies that there is some interference present even when the fridge is off. If so then you are receiving a weak signal from your antenna.
OEM antenna-on-glass are a compromise and deliver a signal that may be adequate in city zones but less so out in the country. Your fridge is generating some RF interference which competes with the signal from the antenna. If you are keen to get radio reception when away from home you may need to consider installing a superior whip-type antenna which will deliver a stronger signal to the radio.
OEM radios are not high performers either, but you would need to be really keen to upgrade that as even though they can resolve weak radio signals they will also amplify the interference entering the antenna.
Having the antenna on the rear window also requires a longer coax cable to the radio which will incorporate more signal loss. It is even possible that there may be some fault in this cable or its connectors.
Sorry that I cannot offer better news!
