AM/FM Radio interference

I have the same problem with an Engel fridge in my Prado 120, but it only affects AM and not all the time. Might try the suppressor suggestion.

HI
Any devise with a basic electronic inverter can cause problems ,fridge 12 fluoros etc
The problem will be worse on AM & in weak signal areas for the particular station you are tuned to
some of the interference
is via the wiring
This can often be reduced by using an auto supression capacitor as close as posible to the fridge[connected between positive & negative Plus some ferrite 'Jaycar part#LF1924over the pos & neg cables again as close as possible to the fridge

If the interference is via the aerial the problem is more difficult
try getting the fridge as far from the radio aerial as possible
keep any cables close the the metal frame of the vehicle
If the fridge has a metal case try earthing that with a short heavy lead to the vehicle body

Thanks for the suggestions. Mine seems to be aerial interference, so I will try earthing the fridge case when I go off on a trip tomorrow.

Oldtrack, I have a similar problem.
Thanks for your suggestions - I'll try them all.
But earthing the metal case - can I just do that inside the fridge by connecting a strap from the case to the negative terminal of the power input on the CB? The neg in the auxilliary socket to which the fridge is connected then goes to the body.

Hi Frank
I did reply earlier just @ the time ofthe short site shut down
It must be still out there
I would rather a seperate short[as possible ] connection direct from the case to the vehicle body
Your option may be ok & I understand you probably just want to be unplug one cable
The problem is that any Rf is going to run side by side with the pos lead.
The idea is to get iit away by the shortest possible route & as far as possible from the pos lead.
If you wish you could use some type of plug & socket, no amperage involved so it does not have to be very big

Thanks Peter. You picked my preference in one! I'll try my way first (more convenient) and if it doesn't work, your way.

If that doesn't work, no AM radio in preference to cold beer!!!

(It's only the AM radio that's affected. FM and my UHF CB are OK.)

Cheers

I am just back from my trip, and earthing teh fridge case worked really well. Thanks so much for the good advice!!
