Default Re: 87.9 MHz FM Car Radio receives phone calls. Explanation?

I think it was down to an EU directive to introduce common standards. They were already legal in some EU countries.

The legal restrictions are still pretty tight, but given the relationship between 'CE' and 'China Export' the market soon became a free for all. The strictly legal transmitters are very low powered indeed.
