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
