Global license-free bands in 25-60 MHz range

Global ITU license-free frequencies

Individual countries may choose the details for their lands, or may open up additional frequencies. Generally this is a place to start.

  • 26.957-27.283 MHz ISM band (ITU RR 5.150)
  • 40.66-40.7 MHz ISM band (ITU RR 5.150)

Country-specific license-free
