The ERO 'European table of frequency allocations and utilisations covering

the frequency range 9 kHz to 275 GHz', available from 
www.ero.dk/doc98/official/pdf/rep025.pdf says, apart from broadcasting,
that 
150 kHz might be used for 'Ultra Low Power Active Medical Implants'. 
Perhaps the spectrum is used in a similar way worldwide.

Probably wouldn't want to interfere with one of them!
