Might #MeshCore and #Meshtastic default presets be illegal (US)?

It sounds like the MINIMUM bandwidth may be 500khz. MeshCore uses 62.5 as default and Meshtastic uses 250 as its default.
If the bandwidth must be raised in order to comply with the law, then the mesh will not go as far, because wider bandwidth equals more noise from the universe, which means lower signal range.
