I hook my caravan battery up to a smart charger while it's sitting at home. It's a new three stage state of the art charger not a cheapie but it causes interference on all the radios in the house, is there a filter or something I can use to remedy this ?

If it does that, then it doesn't comply with Australian Standards. Talk to your supplier, you may have a faulty unit.

- agreed, some interference is normal on a radio beside the charger. Interference radiating a long way is a fault or a cheap and nasty and non-compliant design.

My smart charger in the van does not cause any interferance to any radios, as said I think you have a faulty unit. Having said that the charger I use in the shed for cordless drills plays havoc with my shed radio if tuned to an AM station, doesn't bother radio on FM.

What brand charger? And does it show the compulsory c-tick logo?
If it's c-ticked, it may be faulty, if not, the seller broke the law by selling it to you.
Sellers are required to produce EMC approval documentation (held by the manufacturer or importer) on request.
Go and get this off him.
If he can't give this to you, you are in a good position to demand another unit from him.

There are two types of switchmode and a lot of makers go for the cheaper switchmode.
The better switchmode has PFC (Power Factor Correction) and this type should pass Cispa 11 or 21 the toughest requirement here for EMC compliance.
