Hello John,
FM transmitters like the ones near 150 MHz have been around for decades. They generally seem to be narrowband (read 'crap audio quality') and often confined to particular ethnic groups or audiences with specific interests. A very quick search on Google gave me this example http://www.radioena.com.au/
Some of these transmitters have been known to use strange methods to stop general listeners tuning in, extracting money from listeners for a suitable decoder box.
cheers,
Ian
