The radiated emissions from cheap flyback power supplies / chargers can be a real problem. There are loads of standards that need to be complied with. But as ever the happy shopper ebay from china ones may not be good enough. As long as you are aware that they can cause trouble with RF then you can take steps to mitigate the effects. So.. next time you have interference, go straight for the phone charger.
