LoRa: amateur bands vs SRD devices
LoRa is a modulation. LoRa APRS, Meshtastic and TinyGS are different applications. Amateur and SRD/ISM bands have different authorizations, power limits and duty cycles. Verify current national regulations and band plans before transmitting.
Meshtastic — official radio documentation ↗Digital frequencies — reference
Conventional VFO dial settings, not exclusive allocations. Check IARU band plans, national rules and current software settings before transmitting. Audio offset differs from VFO frequency.
